Hey there, fellow ProForgers! how is your first print looking? This is mine so far
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
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 printed part that’s not for calibration.
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!
There‘s a lot left to be tuned but klipper‘s keeping up ;)
