Have a question about this project?

His logic is flawed. If you must use calipers, a quality brand is preferable.Enter the filament diameter value into your slicing software and make sure that your extrusion multiplier is set to 1. D9 is for the part-cooling-fan which will get controlled by your g-code. How can I ban you from doing that?

Mur, Rainuré bouveté / I have no part cooling fan on my Prusa and my extruder fan is connected to D9 and automatically comes on after 50ºC and turns off bellow that! Thank you for all the info and help. It works with M106 S255 command, so I know it is properly connected and the MOSFET works, but it will not come on automatically when the hot-end passes 50ºC !!

Measure the distance between the point that you marked before we started, and where the plastic enters the extruder (the same point from which you measured the initial 120mm). Locate it and record it.

His logic is flawed. :). didn't have the previous files where in a laptop with a crashed HD. Have a fabulous day! If you're finding that your prints look like they're over extruding or under extruding, double check your filament diameter and make sure it's the exact same as what you have in your slicer. Correction multiplier × original extruder steps/mm = calibrated extruder steps/mm:

You are a shame for the 3D-Printing-Community.

In order to calculate what our new steps/mm value will be, we need to know the existing steps/mm value, and the under/over extrusion rate. I tried it and it works.

The head will move in a coordinated fashion such that both axes complete the travel simultaneously. @thinkyhead Never mind mate, keep up your good work. There are two parts to calibrating your extruder - tuning your extruder steps/mm value, and tuning your extrusion multiplier. Your Extruder Fan (the fan which cools the Extruder, NOT the part-cooling-fan) isn't (or shouldn't be) connected to D9. I think you are missunderstanding something there.

GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. To make sure that this has all worked out as intended, turn your printer off and on or reset it and then send the command. I think it's 1.1.0?

Adjust your extrusion multiplier to: (current extrusion multiplier × extrusion width) / measured wall thickness.For example, since my walls first came out as 0.5 mm even though my extrusion width is set to 0.45 mm, my extrusion multiplier would need to be changed to (1 × 0.45) / 0.5 = 0.9.Enter this into your slicer and print the model again and re test.

There is part of the code which is the control logic, and another part is the configuration.

I don't know what you expect to achieve by insulting the project curators.

This issue has been automatically locked since there has not been any recent activity after it was closed. en savoir plus The reason for extruding so slowly in this step is to ensure that the resistance of the plastic further down in the hotend does not affect how much is fed in by the stepper motor.

Any help would be appreciated. Press the space key then arrow keys to make a selection. To do a final test to make sure it's correctly calibrated, measure out another 120 mm of filament, mark it, and then extrude 100 mm. For more information, see our Privacy Statement.

:). It may also vary between different brands of the same material type too, so keep this in mind. @PicoPi, If you do not respect the other programmers there is no place for you here. @PicoPi — We get some amazingly odd and immature characters around here sometimes. Stop doing that.

I have done this a few times and checked my math.

Isolation des toitures par l'extérieur (thermique, ...) / I need help. Why is the version number not in Marlin.ino?

If this is exactly 20mm, congratulations!

By clicking “Sign up for GitHub”, you agree to our terms of service and So I’m not sure where to go from here. You wont be disappointed!

What you do or don't do with it, is not my concern. We can do this by printing a single perimeter cube and adjusting the extrusion multiplier so that the width of the walls is the same as the extrusion width set in the slicer.

no need for the devs to get active on anything here. Moins de 50 / I wish github gave a jac**ss of the day trophy.

going through them step by step if you don't have them anymore, anyways, "error" solved, error was caused by just not paying attention. Extrude 100mm of plastic with the command G1 E100. Then we'll measure how much plastic it extruded and see if it actually was 100mm - pretty simple! Actually, most printers have extruder fans that are always on, connected straight to a 12V plug with no digital control. DEPRON / Whomever made this change, should stop working on the code immediately.

Sol sous-chape / Some one has changed this from the default it used to be!

Who puts a parts fan and not an extruder fan?

We're only interested in the E value, highlighted in the picture below. That's why you can activate it via g-code command. If I use the servo port pin 11 for E0_AUTO_FAN_PIN, it will turn on a fan that is connected to an external MOSFET like TinyFan board when the temp reaches 50ºC !!! Leave the extruder steps/mm as stock, and go straight to the extrusion multiplier calibration step. The reason I ask is because some of the filaments I use are severely underextruding, but some print perfectly.

EVERY printer needs an extruder fan, but not every material used for printing needs cooling i.e. Try testing with another filament from a brand you can trust, preferably with a good diameter tolerance.If you're located in Australia and you're after a filament you can rely on, give Matt's Hub a try! By the way.

Pretty harsh words for just missing to compare the new configurations to your old ones or going through them step by step if you don't have them anymore.

Codes for print head movements follow the NIST RS274NGC G-code standard, so RepRap firmwares are quite usable for CNC milling and similar applications as well.See also on Wikipedia's G-code article.

I don't know if it is possible to ban people here, but this person would be a perfect candidate imho to refuse him total access to the bug-section of your git.

Whomever made this change, should stop working on the code immediately.

After you have completed all these steps, it’s a good idea to tune or re-tune your first layer height, which may need adjustment.

Once the machine has finished extruding the 100mm, switch off the hotend heater. Carton de 10 plaques /

Aren't you using any part-cooling fan or why do you want to pick D9 for your extruder? Des remises régulières, la reprise de marchandises pendant 12 mois et bien d’autres garanties !

I think you guys are doing a really good job with this firmware, keep it up!

For now it can be found in Version.h. Learn more. I was doing some research for the autofan options and I came across this issue gem lmao. Give it a try, maybe it works, maybe not. Isolation des murs par l'extérieur (thermique, ...) / For example, to use the default pin for E0_AUTO_FAN_PIN: Or, redefine to the pin you want to use, and it will override the default: Since the common FAN_PIN (part cooling fan) has a setting for all boards and is always defined, if you need to use that pin, you would have to comment it out in the relevant pins_MYBOARD.h file. So, to calculate the new, correct extruder steps/mm value, we perform the following calculations. Enjoy printing knowing that you have it dialed in perfectly.If you're still experiencing issues with your extruder intermittently under or over extruding, the issue may be your filament. they're used to log you in.

First measure out 120mm of filament from where it enters your extruder and mark it with a pen or marker.

You can always update your selection by clicking Cookie Preferences at the bottom of the page. This will be the reference point. Adam, the extruder steps calibration can be done once for your printer, but it is a good idea to do the extrusion multiplier calibration for each different filament that you use. Your extruder steps/mm are perfectly calibrated. Connect your computer to your printer and open up a program that allows you to send individual gcode commands to it (like Pronterface, Simplify 3D, Repetier Host, or Octoprint web interface).

Our filament diameter is strictly regulated at 1.75mm ±0.02mm, and it's made using high quality virgin resin from NatureWorks USA for great consistency in flow and mechanical properties.

We'll have to add that. Print it out and measure the thickness of each of the walls and calculate the average.Your aim is to get this to be the same as your extrusion width set in your slicer.
