![]() ![]() Measure where the mark on the filament is in relation to where you measured from. In MatterControl, extrude 100mm of filament. Using some stationary point on your extruder, measure 110mm on your filament and mark it with a felt tip pen. If not, you can repeat the same process, paying special attention to getting as accurate a measurement as possible.įor Direct extruders, the process is a little different since you must extrude the filament through the hot end.īring your hot end up to temperature for the filament you will be using.įeed filament into your extruder/hot end. ![]() Measure, and you should be right at 100mm. Set the filament back flush with the Bowden tube and extrude 100mm. The last step is simply confirming our new value. In MatterControl go to Advanced Controls > Configuration > EEProm Settings ConfigureĮnter the new value in the proper box, click Save in the bottom left corner. Now we just need to enter our new value into our EEProm settings and we’re done. I measured 101.3mm on this Rostock max.New Steps/mm = (Old/Current steps/mm) x.We need to do some basic math to calculate the proper steps/mm for your machine It can be shortened to “Extr0” or “Extr1”, but it should be easy enough to locate.įor this example, I’m using a Rostock Max by SeeMeCNC and the field is “Extr1 Steps/MM”. The current value is 93 steps/mm. We are looking for the “Extruder Steps/MM” box. Advanced Controls > Configuration > EEProm Settings ConfigureĮvery printer/firmware combination will look a little different in this window. If you have a dual extrusion machine, this can be named Extruder 0, Extruder 1, or Extruder 2, depending on your printer. Now we need to locate the current value your printer is using to calculate extrusion distance – Extruder Steps per MM. If the measured amount is LESS than 100mm, then you are underextruding. If the measured amount is MORE than 100mm, then you are overextruding. For best results, repeat this process 3-4 times – align filament with edge of Bowden tube, extrude 100mm, measure – and take the average. When the filament is done extruding, measure from the end of the filament to the end of the Bowden tube. If the filament does not feed when clicking the Extrude button, heat the nozzle to at least 200C and try again. * Please note that some firmware will not extrude if the nozzle temperature is too cold. Select “100mm” under the Extrude/Retract buttons, and Extrude 100mm. In MatterControl, go to Advanced Controls and click on the Controls tab. Make sure filament is flush with the opening of Bowden tube. You want a nice, flat cut so that it’s more easily measurable in the next steps. Using a razor blade or sharp scissors, cut the filament flush/square with the Bowden tube. ![]() Leave it attached on extruder side.įeed filament (any filament except flexible filaments like Ninjaflex) through your extruder until it just starts to come out of the Bowden tube. Remove Bowden tube from the hot end side. Ensure hot end and heated bed (if applicable) are turned off and cool to the touch. Direct and Bowden extruders are very different, but calibration is similar for both.Ĭonnect your printer to MatterControl. ![]()
