Use this to reset, center, and auto-extrudea small bit before printing.


G90                         ; Explicitly force absolute positioning in case it was not reset previously.
G28                         ; Home all axes.
G29                         ; Auto-level the bed.
G0 X0 Y0 Z0.15 F9000        ; Move to the front-left part of the bed.
M109 S{print_temperature}   ; Set and wait for extruder temperature.
G92 E0                      ; Zero the extruder.
