#########################
G91 ; use relative positioning
;******* Change F250 in the following line to F2500 when you are finished commissioning
;******* Change 320 in the following to a higher value if your Kossel has taller towers
G1 H1 X320 Y320 Z320 F2500 ; move all carriages up 320mm, stopping at the endstops
G1 X-3 Y-3 Z-3 F2500 H2 ; move all carriages down 3mm
G1 H1 X6 Y6 Z6 F250 ; move carriages slowly up 6mm, stopping at the endstops
G1 Z-5 F2000 ; down a few mm so that we can centre the head
G90 ; back to absolute positioning
G1 X0 Y0 F2000 ; centre the head and set a reasonable feed rate
