Need help with PETG on MP Ultimate Maker 2
Hi everyone,
Im new to 3D Print and I have a lot of trouble with my PETG settings in Cura 4.8.0. Im printing on a MP Ultimate Maker 2 (firmware 2.2.8) with a Black Geeetech PETG filament.
I tried a lot of settings in the past days and the prints are getting better and better. Today I decided to get rid of the stringing problem with this "string test". Thingiverse - Digital Designs for Physical Objects - Thingiverse
I also was printing a heat tower today and it looks like 235 - 240 is the best temperature. But if I try to reduce the stringing the rest of the print gets messy.. the two towers are super instable etc.
These are my GCODE Scripts:
;(**** start.gcode for Ultimate2 (150S)****)M140 S{material_bed_temperature_layer_0}; Set bed tempM104 S{ material_print_temperature_layer_0 }; set extruder tempG28 ; Home extruderG92 X200 Y150 Z170G29G1 Z15 F100M109 S{material_print_temperature_layer_0}; wait for extruder tempM190 S{material_bed_temperature_layer_0}; Wait for bed tempM107 ; Turn off fanG90 ; Absolute positioningM82 ; Extruder in absolute modeG92 E0 ; Reset extruder positionG1 X140 Y7 Z0.27 F4000G1 X40 Y7 Z0.27 E23 F1000G92 E0;
(**** end.gcode for Ultimate2****)G1 X170 Y130 F3000G92 E0G1 E-10 F1680 ; Reduce filament pressureG1 Z150 ; Get extruder out of way. Uncomment to use!M107 ; Turn off fanM104 T0 S0G90 ; Absolute positioningG92 E0 ; Reset extruder positionM140 S0 ; Disable heated bedM84 ; Turn steppers off
I hope you can help me a bit with that. :)
