Re: A20M : what stepper driver it uses?

If your board is the GT2560 rev3 it should work. I'm using TMC2209 on it (with Marlin 2.0). You'll have to build your own firmware to make sure drivers configuration is set. Very silent on XYZ. Hi ThaDogg, please can you share what brand and version of the TMC2209 you are using on your Gt2560 and h...

Re: extruder clicking, filament not feeding properly

Check you have the right settings for your slic3r. I upgraded my Silc3r from the default version that came with Repetier-Host and it didn't keep the original config, so I had to download them from the link in this thread https://www.geeetech.com/forum/viewtopic.php?t=18536 and reimport them in my Sl...

Re: Extruder Calibration Issue - SOLVED

I fixed my issues by completing the extruder speed calibration with the following command. G1 E100 F28 (If my maths is correct F28 equates to about 50% of the recommended nozzle flow rate of 35mm/s). Once I set my E-value based on the measurements from this calibration test I have much better result...

Re: Extruder Calibration Issue

Ok, I think I might have answered my own question here. I did some maths to convert the input rate to nozzle flow rate based on the standard 1.75mm and the Geeetech 0.3 nozzle. It turns out that an input flow of 100mm/min (i.e F100) is around 55mm/s at the nozzle, way over the 35 mm/s in the default...

Re: extruder clicking, filament not feeding properly

My printer clicks when its going too quickly, 40mm/s seems to be my "max" speed to deliver a great print and produce no "clicking noises". Hi, where did you change the max speed value? I’m using RepetierHost with Slic3r and I’ve still not got my head around where the settings are pulled from and wh...

Extruder Calibration Issue

Hi, I'm having some trouble calibrating my mk8 extruder using the guide here ... https://mattshub.com/2017/04/19/extruder-calibration/ I'm using PLA with a nozzle temp of 210 but the amount actually extruded seems to change slightly every time I ask the extruder to push through 100mm. I eventually s...
