I’m trying to get my startup routine optimized in Slic3r (among other things), and I’m having some trouble. Here’s what I’ve got:
G21 ;metric values G90 ;absolute positioning M82 ;set extruder to absolute mode M107 ;start with the fan off G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G1 Z15.0 ;move the platform down 15mm G92 E0 ; zero the extruded length G1 F200 E0 ; extrude 3mm of feed stock G92 E0 ; zero the extruded length again M117 Printing... ; send message to LCD
From what I understand, this should go X-Y home, Z-home, Z+15mm, extrude 3mm, then head to the rest of the gcode to start printing.
However, instead it seems to be moving from Z=0 to the gcode start position. While it isn’t dragging on the bed, because there’s enough clearance, this doesn’t seem like the best procedure. Any thoughts on what I’m doing wrong, or does anybody have a great TAZ 5 slic3r start/end gcode or filament profile?
