There‘s a lot left to be tuned but klipper‘s keeping up ;)

Pretty decent for the second print! Used the Ender3 profile in Cura and changed my Stepper Current for the Extruder from 340mA (way to low) to 500mA

Gcode: M906 T0 E500

save to eeprom with M500

check value with M503

used a height of 0.2 and a 0.5mm nozzle

Thanks for the hint!

Just checked datasheet on the extruder, depending on the reference 2 different limits can be set:

"0.5A Peak or 0.35A RMS (LDO-36STH17-1004AHG and LDO-36STH20-0504AHG)
1A Peak or 0.7A RMS (LDO-36STH20-1004AHG)

NOTE: Please pay attention which current type your firmware is configuring and set accordingly:

Marlin and Klipper firmware RMS currents are configured"

In my case I have the LDO-36STH20-1004AHG so I can change to 700. I now understand better why I have under-extrusion issues!

First printed part that’s not for calibration.

Had a lot of issues with retraction but finally could make a benchy! I will try to increase the extruder current, quite sure it will solve the print fails anytime i activate retraction. Now if i put anything more than 0.1mm the extruder struggles every-time after a retraction.

First Benchy done with Klipper, input shaping und pressure advance. Did this in pretty much exactly 30 min and it came out perfectly, except for a little bit stringing, but I guess that is normal for that PETG.

don’t mind the material at the bottom, that’s just brim
