Actually it doesn't really matter what the temperature exactly is, you just need to find the sweet spot for your filaments on your machine. This can be done from the printer's interface or in a terminal, by entering the following (this example is 100% fan speed): It is not essential, but you may prefer to start this process with the hot end at room temperature. This is to remove portions with elephant's foot and/or other abnormalities. This means requesting 100mm of filament adds 100mm to the current position, instead of moving to the specific position of 100mm. @AnHardt Ill take a look if that behavior changed when I make it around here on my list. If steps are being skipped/missed. As the linear advance K factor is filament dependent, this may not be the best solution if you print with varied filaments, and instead you may prefer to save using your slicer profile. Examples include finding a safe feedrate for a difficult to extrude flexible filament, determing the maximum reliable feedrate when trying to print faster, and tuning outer wall speed to reduce 'noise' on external surfaces. The speed at which our 3D printer (or any CNC machine) moves is better described as 'feedrate'. If the wheels are too tight: The assembly will be too tense, which will wear the V-rollers prematurely. To save for a printer with jerk (with a determined best compromise of 8 for this example), we would enter: To save for a printer with junction deviation (with a determined best compromise of 0.05 for this example), we would enter: Either way, we save to EEPROM afterwards with: Each of these parameters can also be entered and stored from the configuration menu of the Marlin LCD. Is understanding classical composition guidelines beneficial to a jazz composer? You can also use the LCD to set the new values and then store to EEPROM to save, although you will be limited to only one decimal place. This is achieved by moving the corners of the bed up and down relative to each other. You then need to resend these to your printer as a M301 command, and this will reset the PID to the new parameters. Higher current maybe required for the E driver, which will make it run hotter. Without the temperature where the difference is 20C, 20c is meaningless. #2 Functionally, for this machine, no. Features such as internal infill are sped up because they will never be seen. A 5-10 C error has little effect if you use the suggested temperatures and has zero effect if you pick the best temperature with temperature towers (and strength testing, if you have the equipment). User had reportedly set it to 315c. RepRapFirmware uses M205 to set Max Instantaneous Speed Change instead of jerk or junction deviation, but the idea behind it is the same. This used to be a laborious process and beyond the skills of many users. It may be necessary to lower this value if you want a particularly slow feedrate for segments of the tuning tower. the definition of beta and compare to Steinhardt-Hart coefficients. Set multimeter to DC voltage, max 2V range. Some slicers support using the calculated volumetric flow rate above as a hard limit. This is harder on the printer, and may result in reduced lifespan of components and the need for more regular maintenance. On a manually levelled bed, the four corner knobs would need to be turned in unison to raise or lower the bed in accounting for thickness of the new build surface. These commands are prefixed with the letter M followed by a number. To work around this, you must compile with DISTINCT_E_FACTORS uncommented/enabled in configuration.h: You will then be able to enter a unique M92 value for each extruder. BLtouch/EZABL/Pinda probe - The nozzle is in mid air when these probes are triggered, which will require a negative Z offset. Most of the time, we want to print as fast as possible, at least up to the point where print quality deteriorates beyond our personal threshold. The settings you establish should translate to your slicer quite well but there may be idiosyncrasies. It has received a major update to bring it up to V2 which is explained in this video: 3D printer calibration site V2 - Still free and better than ever! Perhaps the flow rate should be used to only make very small adjustments. Complementary to acceleration we have jerk, replaced by junction deviation in newer versions of Marlin. If your distance is anything other than this, complete the form below to calculate the correct E-steps: Measurement between extruder entry and mark on filament (mm): There was mm of filament remaining, which means you extruded mm of filament. Some users are naive. Sometimes the ability of the heater is not the limiting factor, and instead the amount of grip and push from the extruder drive. A good starting point for a direct drive extruder is 0.2. Your maximum reliable extrusion rate is 7.22 mm per second. Therefore we want to measure the movement of each axis when not printing, comparing target vs actual movement. Print settings > Advanced > Extrusion width > Default extrusion width: Print settings > Width and flow > Extrusion width > default: 5. This can be set in the firmware, via a terminal or by using the printer's LCD. To determine the correct amount of steps Marlin firmware needs to send to the extruder stepper motor for accurate movement. Number of parallelograms in a hexagon of equilateral triangles. Marlin has excellent linear advance documentation and a test gcode generator already made, so there is no point recreating a competitor here. We can store the new value(s) to EEPROM by sending: You would then repeat the test with all of the acceleration values locked at your preferred value for each segment, but this time varying jerk/junction deviation. They are the same thing. Most new users will trip up on this. (I guess they spent money and get experience for that - not a bad deal - even if the part is completely unusable - or - especially then - compared to the tires it's a cheep experience.) TonyKYOctober 15, 2020, 9:13pm #3 Let's say your old flow rate was 100% and you have tested and corrected this to 96%. Sliced for Marlin firmware, although in most cases will still be compatible with other firmwares. It is worth heating up the nozzle and pushing some filament through to see if it is exiting the nozzle properly. This was a one off, the cartridge type they sell works the same way. The gcode generators on this site work by using javascript to modify source gcode originally created by Simplify3D. Excellent video, showing how to make a temperature table with a external reference thermometer. Here thermistor types vary much more. You can enter M503 into a terminal and these values will be reported. You can use these to turn the levelling knobs in each corner until they are consistent, or ensure your ABL system is working if you have one in place. Mini). This is what I said because it sounded more like an issue with the thermistor or his board. This is simplified test that will not be as accurate as using the gcode generator on the Speed/Max flow tab. For this guide, I designed and printed my own dial gauge mount to suit a 12mm round rod base, and a printhead mount to suit the printermods.com xchange system: Dial gauge mount on Thingiverse. You signed in with another tab or window. It has a significant impact of retraction (reducing the need), so after configuring linear advance you may need to revisit retraction. We do initialize the min/max-ADC values from the opposite side. If there is no UI button available to turn on the part cooling fan, you can do it manually via gcode with M106 S255. When the algorithm would't find a value, the MIN/MAX-TEMP_ERRORS would appear as soon as active. Watch the videos and then work through each tab. Is it common practice to accept an applied mathematics manuscript based on only one positive report? A build volume of 120 x 120 x 250 mm (This site can accommodate anything as small as this and anything larger), Absolute extrusion values (M82 as opposed to relative/M83), 0.4mm nozzle and 0.2mm layer height, although now additional configurations are now possible, Line width on auto, typically 120% of nozzle diameter, Defaut feedrate of 60mm/sec. Retraction acceleration: This will affect whether the retraction speed can actually be reached. rev2023.6.12.43489. Most slicer programs for you 3D models have a terminal command section. For arguments sake, let's presume you have set a temperature of 210C for the extruder. What's the process for recalibrating the hotend temperature readings? Printing the gcode generated by the pattern generator with yield a result like this: Some of the horizontal lines should have obvious thick and thin portions, and some may even have large gaps. In order to test PLA, we normally use 205 degrees or . Navigate to the Temperature menu. It works with some thermocoupl systems but would be disastrous when shorting a reference thermistor. - Ex2: A video showing this issue: https://youtu.be/brl1weuD8bs. An example of this situation is shown in the video above. A different value is required for each filament to get the best results. Most difficult part of this is placing the the two sensors so, that they get the same temperature. Marlin documentation should have a well documented troubleshooting process for when this issue arises. Brought to you with lack of and lots of . Does a drakewardens companion keep attacking the same creature or must it be told to do so every round? There are mainly two kinds of stepper driver boards with this driver. Otherwise, I agree with the above. If you can't replicate the results, please work through the following: To set the ideal printing temperature for the hot end for a given filament. The results from this should still be reliable. Instead here we are tuning the temperature at which the filament is extruded. - Ex2: A video showing this issue: https://youtu.be/brl1weuD8bs. Forget it. Which formula you use is based off of this resistor. This site is not a web based slicer, therefore it is limited in some ways. Temperature from thermosensors gets collected as a resistance value that changes with temperature. For X, Y and Z, the stepper motor may be undersized for the mass it is pushing. Like the TMC drivers covered in the gcode section, the current for the TMC2208 (legacy mode) is set not as a peak, but instead as RMS. 3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts. S3D offers multiple processes to assist with splitting the towers into segments where the print settings can vary. If there is a significant defect, the culprit will likely be found by working through the frame tab. NTC Thermistors are only supposed to be off 2.0 C. Many people are familiar with E-steps, which is the value in the firmware that dictates how many steps the extruder stepper motor needs to rotate to push through 1 unit of material (typically millimetres). All our reviews are based on our personal experience and deep research. With these characteristics, the transfer of filament between extruder and hot end is more direct with less time delay. This means we can increase the print feedrate without worrying about the travel feedrate being proportionally increased to a dangerous value. For example, if you set the M204 print acceleration to 1000 but the M201 Y acceleration limit is only 800, then the M204 P value will be capped at 800 for Y while printing. You may need to home the machine first, as some firmware configurations will not allow manual movements until this takes place. In this case, all movement for that layer is slowed, including those related to retraction, to increase the layer time to meet the target. Before general calibration or before a significant modification is to be fitted. There has been no update since the conversation. As with everything, Marlin isnt perfect and issues crop up from time to time with many of its settings. It appears like cobwebs: Temperature tuning and retraction tuning are related to each other. Required. In the example below (Ender 3 direct drive, PLA, linear advance enabled), acceleration varied from 300 to 800 in 100 mm/sec/sec increments. Ensure wall thickness is a known value. Linear advance is incompatible with certain stepper motor drivers. Bed and nozzle temperatures should now be the same. The T value represents travel acceleration, when no filament is being extruded. Part surface may be duller. It also introduces more surface defects such as ringing/ghosting. A value of 5 mm/sec will allow the toolhead to slow to and maintain a 5 mm/sec speed for a 90 degree corner. Strip out all comments apart from new processes and layers. However, it is up to each individual to decide the tolerances they expect their machine to operate within and whether a course of action is required to improve this. However, its not important whether you know them all, just the ones you need! Because of the above reasons, vase mode makes it ideal to use the. This G-code is used to calibrate the temperature drift of the PINDA (inductive Sensor). If you print another job afterwards these higher values will still be in place. Travel acceleration: This test does not manipulate travel acceleration but increasing its value may help reduce stringing. It is important to remember just how small this distance is. Setting stepper driver current accurately relies on knowing two values: the peak current that the stepper motor is rated for and the sense resistor value on the stepper motor driver. Designate special limit grade wire using a double ANSI/ASTM symbol (e.g., KK, JJ). How do I calibrate the extruder of my printer? Initial setup of the printer, regular maintainence, if first layer quality diminishes, any time the frame or mechanical components have been disassembled or replaced, any change of bed surface or nozzle, a change in filament that has significantly difference bed/hot end temperatures. The cycles refer to the number of times the temperature runs around its target of 200 C and sends results back to determine the correct target: in this case 8. Article Contents show Calibration checklist Extruder screw is too tight / too much pressure on the filament A common issue I noticed on the Sidewinder X1 is the amount of pressure the idler lever puts on the filament. This step is not necessary for many people, but is still worth doing if you are going over the machine in detail. To see it in action, see the videos below: To tune the timing of the extrusion with the aim of reducing swollen corners and thinner walls. An example of setting the X axis current to 680 would be: Don't forget to save the value to EEPROM afterwards with: Finally, the LCD Configuration menu can be used to set the RMS current. In the case of using ABL, to check if compensation is working and the Z offset is correctly set. In this case, you need to insert M301 (hot end) or M304 (bed) into your slicer start gcode so the correct settings are loaded before each print. To establish a baseline for comparison with later tests or before modifications. The linear motion of the dial gauge must be parallel to the motion of the axis being measured, or perpendicular to the object it is pushing on. This is easier on the printer, with potentially increased component lifespan and less need for regular maintenance. Your slicer profile settings will also be different in other ways, which further complicates matters. Therefore, it follows that you can change the PID setting to whatever you need it to be. I say this as well because I don't happen to see a well documented way of making sure that the thermistors that we get are accurate. In many cases this would be irrelevant to the printed object. If you are not interested in printing as fast as possible, skip to the next section. You can change travel acceleration with. Our E-steps are now correct in the firmware, so we will move on to calibrating the slicer. Especially when combining random with random. This is an optional step, and only applies to specific scenarios. The parameter we tune for linear advance is called the K factor. Marlin 2.0 should be able to tell you when a thermistor value may be wrong or show an error. I was actually thinking of building a rig to test thermistors using a lab calibrated heating source. It's also worth noting that the M201 value acts as a per axis limit for acceleration. The PINDAv2 sensor has a built-in thermistor which has the advantage that the calibration can be done once for all materials. While Marlin offers a PID tuning setting that can be enabled for use within the LCD. While this is a valid measurement for determining how accurate the output of the printer is, it is NOT the correct measurement for calibrating X, Y and Z steps. Before you start, youll need to download a G-Code terminal such as Pronterface, which is compatible with most 3D printers, or if youre familiar with Octoprint you can use that as well. For leadscrew driven motion, an anti-backlash nut can be fitted as a potential remedy. It should be sliced with a normal base, but hollow, no top layers and only 2 perimeters. One strategy is to calculate the fastest your 3D printer can move while extruding cleanly, set this feedrate in the slicer, and then tune acceleration to meet this speed. Newer versions of Marlin also have a Z offset wizard that can be included when you compile. Unfortunately, there is no official reference for this provided by S3D. Where can one find the aluminum anode rod that replaces a magnesium anode rod? Some printers may have a combination of hardware and software that produces noise or surface artefacts with feedate as a factor. This procedure is covered in this video: Two easy fixes for 3D printer temperature swings. Then check a second time with the new table. Below, you can find a step-by-step guide that will allow you to PID tune your Ender 3 in a straightforward way: Navigate to the Configuration menu on your Ender 3 LCD controller. The following form will create a retraction tower to conveniently test back to back parameters in the same print. Yes, we do care about the accuracy of the final part, but we need a better way to measure X, Y and Z movement. The gcode on this site originally had a flow rate of 90% when sliced, so applying your 96% to that gives a final result of 86.4%, not 96%. Ender Extender kit), adding something heavier to the bed (e.g. You can also issue two 10mm movements and see if any error is consistent. After you find the limiting speed, back off and repeat the test at a lower feedrate several times in a row until you are confident of reliable and repeatable extrusion. While interesting, it's not needed. Traditionally the movement of the extruder is matched to XY movements of the printer, so this means the start of a line will be under-extruded and the end of the line will be over-extruded. For older drivers, methods for determining this are seen in the following snippet. The only extension to this area im looking to make is clamping MIN_TEMP and MAX_TEMP to the thermistor table limits to prevent dangerous scenarios when out of the table. To determine RMS, divide the peak current by 1.41. Enter your reliable feedrate and filament diameter below: Enter the following settings from your slicer: On the Marlin LCD menu, go to Configuration > Advanced Configuration > Steps per mm. Initial calibration, any time the hot end is changed, when trying a new type/brand of filament. There are a few indicators. NVLAP Accredited Calibrations. Higher temperatures obviously need more power and will take time for PID to kick in as it comes close to the target. An example of this could be that the target temperature for your heated bed could be set to 110 C which you might straight away say is fairly high. Sometimes a machine can be upgraded to make it more accurate. Complete beginner's guide to 3D printing - Assembly, tour, slicing, levelling and first prints, Two easy fixes for 3D printer temperature swings, XYZ 20mm calibration cube by iDig3Dprinting, Calibrating your XYZ steps using a dial gauge for maximum accuracy. I want to get my Ender 5 plus to print at 300 C. Then test a third time with swapped thermistors and tables to exclude different reference (pullup) resistors. He was probably talking about something along the lines of Arctic Alumina or Artic Silver thermal pastes. Use the buttons in your chosen software to move one axis a designated distance. 4. The ideal segment will have the best compromise between low acceleration corner bulging and high acceleration ringing. A 0.1mm feeler gauge can be used, but make sure it doesn't have any oil on it that will contaminate the bed surface. Entering M503 via terminal will give a list of printer variables: The image below shows an example of each of these scenarios: Use the following form to customise the gcode to your liking: Klipper uses both ACCEL and ACCEL_TO_DECEL. Once you have an acceleration value you are happy with, you can edit config.g with: where 400 is the value of the acceleration with the best compromise based on the tower test print. You may disable this in the slicer, but if your part cooling system is insufficient, the walls may become very hot and deform. It has a higher degree of difficulty due to needing more parameters but is ultimately more powerful. In a manual system, this is achieved by turning the levelling knobs in unison to lift or lower each corner the same amount. All methods are covered below. Already on GitHub? If you find it helps you and you would like to say thank you, here is a donation link: PayPal.me. This file has been updated to V2, which changes the external shape from circular to pentagonal. The controls follow a derivation of G-Code commands and as such are fairly straightforward with common sense settings. Slicer settings such as coast and wipe: Coast stops extrusion slightly early to assist retraction. You would then repeat the test with all of the acceleration values locked at your preferred value for each segment, but this time varying max instananeous speed change. Your 3D printer firmware will have a minimum hot end temperature extrusion is allowed and a maximum hot end temperature for safety. In my slicer, I can slice and print at 300 C, however, I cannot manually adjust the temperature on the LCD screen past the stock setting of 260 C. Keep this in mind and focus on the aim of each test, rather than the general print quality. Some people prefer to have multiple walls and measure them together. This is where the auto-tune aspect of the command comes into play as the cycling of the temperature setting is designed to maintain a constant heat and auto-adjust or tune as necessary. If it can wiggle or the mount can flex, the reading will be inaccurate. - Temperature. In extreme cases, there will be no way for the filament to exit the nozzle, at best causing extruder stepper motor skipping, and even potentially even jamming the extruder/hot end. Like the TMC drivers covered in the gcode section, the current for the TMC2100 is set not as a peak, but instead as RMS. For the the same (correct) target temperature (and the same environment conditions and same 'system') it produces fairly repeatable results when done with a high amount of cycles. Once you have determined the correct value, it must be saved to the firmware to take effect on subsequent prints. Other times pre-sliced gcode was used from the internet, but it is impossible to have gcode available for every printer configuration. When editing config.g, do not omit the arguments for Z and E. Only X and Y potentially need modifiying for this test so leave the values for Z and E untouched. To convert the peak current from stepper motor specs to RMS, divide it by 1.41. The Heated Bed is the surface onto which your filament is extruded to print your chosen 3D model. 0:00 / 10:55 Intro Marlin Thermistor Calibration (not PID tune) Da Hai Zhu 5.73K subscribers Subscribe 37K views 4 years ago Is your hot-end thermistor lying to you? Don't expect differences much less than 1% of resistance. Wire conforming to special initial calibration tolerances, wire for use at sub-zero temperatures, and wire with certified traceable calibration is available on request. to your account, Feature Request: Temperature Sensor Calibration Tool and Troubleshooting Documentation. Change the number in the command to reflect the temperature at which you normally extrude. 19. d) Filament with known melting temperature is melting far above/below measured temperature. In theory the will have all the same resistance and ADC-reading at this temperature. As expected, surfaces becomes more glossy as the temperature increases. I saw an MFG set min_temp below the table and max_temp above. That could be difficult for some of the 'handmade' tables having extra high/low values at the start and end of the tables. Are you looking for hardware support? Marlin limits the maximum feedrate with the M203 gcode. Linear advance requires aggressive acceleration for the extruder and will work the motor harder. When the printer is next restarted the value stored in the EEPROM will be restored. If using PETG, set a temperature of 225C. Many of these procedures are covered in this video: Complete beginner's guide to 3D printing - Assembly, tour, slicing, levelling and first prints. Use M503 to see the current M201 values, and if necessary, use M201 to set higher X and Y acceleration limit values to suit. Have a question about this project? Why did banks give out subprime mortgages leading up to the 2007 financial crisis to begin with? The reason for min_temp to be set low was removed with the change to only monitor when a heater is active, so now its unlikely they would have been open on both ends like that though. The acceleration/jerk and printing speeds are too aggressive for the stepper motors. When new print starts the value given it its start gcode will overwrite the previously set value. To find the maximum feedrate suitable for the outer walls, in terms of surface artefacts, flow rate and reliable extrusion. This is why I personally prefer a single wall cube, but each to their own. Changing more than one parameter makes is hard to tell what made the difference. Thermally conductive is what he should have been going for. See Probe Temperature Compensation for a more detailed explanation of the process. R25 = 100 kOhm, where R25 means the resistance at 25C. It makes sense to do it as a first step. Factor in the tiny movement that comes via your hands in supporting the dial gauge and you have another contributor. No/wrong specification -> random result. Would easy tissue grafts and organ cloning cure aging? The PID auto-tune function is not alone in this respect and there are a few commonly encountered issues that you may come across as you use it. If the wheels are too loose: Wobble will be present in the assembly, which will show in the print as surface artefacts. For marlin the settings are in Configuration.h under 'Thermal Settings'. This is because the filament can flex sideways in the tube in between the extruder and hot end, adding to the extrusion time delay. There is no universal temperature for a given filament. Certainly, if you own or have used a Fused Deposition Modelling (FDM) 3D printer yourself, you will be aware of Marlin. This includes but is not limited to: mainboard cooling fan, heat sink fan, part cooling fan, PSU fan. Once done, remember to save again with M500. Even if you have PTFE hotend setting 250 C and getting 255-260 C won't destroy it. For older stepper motor drivers: a multimeter, small screwdriver and a spare wire with alligator clips (optional but recommended). The timeout is currently set to 15min to allow the parts to fully heat up and cool down. I would then repeat the test, setting the same retraction distance for each segment and instead altering the retraction speed to dial that in. It now uses a variable power approach which allows for fine adjustments and smarter, more accurate output. Once again save to EEPROM afterwards with: It may be preferable to have the printer as close to printing conditions as possible during these tuning procedures. This is where the Z offset comes in, which is simply the vertical distance between where the probe triggers vs the nozzle tip. It reduces surface artefacts such as ringing/ghosting, unless it is far too conservative, in which case it may introduce bulging in corners. Any of these could cause your print to fail, or at least be of poor quality. You will also find the XYZ 20mm calibration cube by iDig3Dprinting referred to on this page, but printing it is not a mandatory part of the calibration process. The process for setting the PID auto-tune for the bed is pretty much the same as for the hotend except that the designator for the bed is different. The process is then mostly the same as for A4988s as shown in the video above, but with the correct formula for your driver board. There is alot of info about thermistors online. Preview the gcode in your slicer or Zupfe GCode Viewer and print at your own risk. These include the type of stepper motor, the type of belt/lead screw, the amount of micro stepping and so on. If you are experiencing significant over or under extrusion that prevents you from using the tests properly, by using the custom start gcode function on this site you can optionally issue an M221 to override the values in the generatored gcode. The print is quick, so repeat the test varying other parameters until you are happy with them all. After PID auto tuning, the final values for P, I and D will be listed in the terminal. "working correctly" means working as specified. If you wish to raise these limits, re-enter 203 and use the X and Y arguments to set the max feedrate, typically in mm/sec. The filament will then very slowly go through the extruder (and hot end). I use Marlin 1.9 for firmware and ideally would calibrate it there--I'd prefer the readouts to be accurate rather than relying on offsets to compensate. Look the current M201 values, and if necessary, use M201 to set higher X and Y acceleration limit values to suit. This may prevent the need for disassembly of the extruder to clear the blockage. Delta Auto Calibration | Marlin Firmware G0-G1: Linear Move G2-G3: Arc or Circle Move G4: Dwell G5: Bzier cubic spline G6: Direct Stepper Move G10: Retract G11: Recover G12: Clean the Nozzle G17-G19: CNC Workspace Planes G20: Inch Units G21: Millimeter Units G26: Mesh Validation Pattern G27: Park toolhead G28: Auto Home G29: Bed Leveling Like manual levelling, we still need to set the distance between the nozzle and bed to get a good first layer. For example, if you set the M204 print acceleration to 1000 but the X and Y M201 acceleration limits are only 800, then the M204 P value will be capped at 800. @AnHardt My first thought was a check with a static assert in each table with preprocessors to just kill it there at compile time. How to keep your new tool from gathering dust, Chatting with Apple at WWDC: Macros in Swift and the new visionOS, We are graduating the updated button styling for vote arrows, Statement from SO: June 5, 2023 Moderator Action, Printer changing temperature after selecting file, Increasing hotend temperature to compensate for increased filament throughput. Marlin 2.0 should be able to create its own thermistor table and save it to SD or output it as text. This can occur when increasing the size of the printer (e.g. If the stepper motors are too hot to touch. Don't forget to save to EEPROM afterwards. To run PID autotune for your hot end in Marlin, you would enter a line of code like this: In this command M303 is the PID autotune tag, E0 is the number of the hotend (P), S200 is the target temperature (I) and C8 is the number of cycles (D). The image below shows examples interfaces for this in several slicers: Sometimes a person will claim they can print at a certain feedrate. The cube should look similar to those at the top of this page. Move around the machine and check all fasteners. Temperature test: 'Process-1' from 0mm 'Process-2' from 9mm 'Process-3' from 17mm . - Ex1: There is an Ender-3 user saying that his temps are off by 20c when tested using a K type vs the stock when measured from within the hot end area. If you are interested in learning more about what is PID, you can check this Wikipedia article where a PID controller is described Find specific lines relating to retraction and zhop, replacing them with comments this site expects to find and modify further. Non uniform scaling of the source STL needs to occur to suit certain nozzle/layer combinations. 3D printer calibration revolutionised - Step by step to better print quality. Marlin 2.0 should be able to create its own thermistor table and save it to SD or output it as text. Marlin needs a feature where you can take a known calibrated temperature sensor/thermocouple and use it to calibrate a thermistor to get the correct temps. Features such as perimeters, external perimeters and solid infill are reduced in speed to aid visual print quality. In minor cases, the extruded line will be wider than necessary and produce elephant's foot. Sub-zero and calibration requirements should be spelled out on the Purchase Order. You may wish to cut/tear off the lower and upper layers of the cube. In the table you can put the float values of the ADC-reading.) A good answer!
