Useful profile / starting GCode to prime extruder

Hello all, wanted to share a tweaked startup gcode profile that I use with the A30 in case it's useful. This makes a priming wipe on the front left of the plate to get the extruder started. I've found it helps with starting up.

Code: Select all

G1 E1.5 F250; (Small retract to help with blobbing on next line)
G28; (home all axes, forces a bounce in the center on the A30)
G1 Z5 F5000 ; (lift nozzle)

; Adapted from MP Select Mini V2 profile in Cura
G92 E0;(Reset the extruder to 0, no movement on this)
G0 Z1 E5 F500;(Move up and prime the nozzle)
G0 X8 Y12 Z0.3;(Move outside the printable area)

; Movement and priming wipes to ensure a clean start
G1 Y80 E16 F500;(Draw forward - a priming/wiping line to the rear)
G1 X9.5 Y14 E32 F500;(Draw backward - more priming/wiping with extra volume)
;G1 E-.5 F250;(Small retract if needed)

G92 E0;(Zero the extruder)
