Custom start Gcode by monopriceman

Last crawled date: 3 years, 4 months ago

Custom priming/ start gcode for mpsm printers, prevents dirtying of nozzles when the old code sends the nozzle into the prime tower. Here is the code:
G21;(metric values)
G90;(absolute positioning)
M82;(set extruder to absolute mode)
M107;(start with the fan off)
G28;(Home the printer)
G92 E0;(Reset the extruder to 0)
G0 Z3 X128;(move extruder far right)
G0 E20;(prime nozzle)
G4 P1000; (wait 1 sec)
G0 X60 Z0;(move left and zero bed)
G92 E0;(Reset the extruder to 0)
G0 X-1 Z0;(Move outside the printable area)
G92 E0;(Reset the extruder to 0)
G1 Y60 E8 F500;(Draw a priming/wiping line to the rear)
G1 X-1;(Move a little closer to the print area)
G1 Y10 E16 F500;(draw more priming/wiping)
G1 E15 F250;(Small retract)
G92 E0;(Zero the extruder)
Copy/ paste instead of old gcode, enjoy and toggle as needed.
here is another one that waits 2 seconds instead of 1 to home itself after the priming blob(sometimes makes it work better)
G21;(metric values)
G90;(absolute positioning)
M82;(set extruder to absolute mode)
M107;(start with the fan off)
G28;(Home the printer)
G92 E0;(Reset the extruder to 0)
G0 Z3 X128;(move extruder far right)
G0 E20;(prime nozzle)
G4 P2000;(wait 2 sec)
G0 X60 Z0;(move left and zero bed)
G0 X-1 Z0;(Move outside the printable area)
G92 E0;(Reset the extruder to 0)
G1 Y60 E8 F500;(Draw a priming/wiping line to the rear)
G1 X-1;(Move a little closer to the print area)
G1 Y10 E16 F500;(draw more priming/wiping)
G1 E15 F250;(Small retract)
G92 E0;(Zero the extruder)
Enjoy cleaner nozzles! Video demonstrating the code in action here:https://www.youtube.com/watch?v=m78eN-DsSxY
Modified gcode that homes and does a prime strip without the blob that dirties nozzles.
G21;(metric values)
G90;(absolute positioning)
M82;(set extruder to absolute mode)
M107;(start with the fan off)
G28;(Home the printer)
G92 E0;(Reset the extruder to 0)
G0 X-1 Z0;(Move outside the printable area)
G92 E0;(Reset the extruder to 0)
G1 Y60 E8 F500;(Draw a priming/wiping line to the rear)
G1 X-1;(Move a little closer to the print area)
G1 Y10 E16 F500;(draw more priming/wiping)
G1 E15 F250;(Small retract)
G92 E0;(Zero the extruder)
And here is one that does the strip only one way( never goes back through the strip)
G21;(metric values)
G90;(absolute positioning)
M82;(set extruder to absolute mode)
M107;(start with the fan off)
G28;(Home the printer)

G0 X-1 Z0;(Move outside the printable area)
G1 Y60 E8 F500;(Draw a priming/wiping line to the rear)
G0 Z3
G0 Y0
G0 Z0
G1 X-1;(Move a little closer to the print area)
G1 E15 F250;(Small retract)
