Prusa Mini Printersettings
Hey,
I'm using the original Bondtech Mini extruder with the Bondtech Heatbreak, but I just can't get the prints to come out the way they should. I think that the settings are not set correctly and I am getting confused.
Can anyone give me some good advice on printing PETG ?
With kind regards

RE: Prusa Mini Printersettings
First if you are using the bondtech upgrade make sure you have set the esteps correctly in the startup gcode (insert M92 E415 as the default value at the beginning of the startup gcode )as the mini doesn't remember this. Also that retraction length is huge, for PETG I have it set to 2mm.
RE: Prusa Mini Printersettings
I've already done that, but it doesn't really help.
G90 ; use absolute coordinates
M83 ; extruder relative mode
M92 E317 ; set steps/unit for extruder
M104 S170 ; set extruder temp for bed leveling
M140 S[first_layer_bed_temperature] ; set bed temp
M109 R170 ; wait for bed leveling temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
G28 ; home all without mesh bed level
G29 ; mesh bed leveling
M92 E415; if you have the extruder upgrade
M301 P13.85 I0.78 D61.77; if you have the heat-break
M104 S[first_layer_temperature] ; set extruder temp
G92 E0.0
G1 Y-2.0 X179 F2400
G1 Z3 F720
M109 S[first_layer_temperature] ; wait for extruder temp
; intro line
G1 X170 F1000
G1 Z0.2 F720
G1 X110.0 E8.0 F900
G1 X40.0 E10.0 F700
G92 E0.0
M221 S95 ; set flow

Maybe not related to your issue, but Bondtech recommends different PID values.

Okay will test it with the original values and Retract 2. I report after the print. 😉
