@monkey68 just tried home all and the y axis drove away from the switch and homing failed so i made the following changes
G91 ; relative positioning
G1 H2 Z5 F6000 ; lift Z relative to current position
G1 H1 X-282 Y-265 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 H2 X5 Y5 F6000 ; go back a few mm
G1 H1 X-282 Y-265 F360 ; move slowly to X and Y axis endstops once more (second pass)
G90
G1 X125 Y105 F6000 ; go to probe point
G91
G1 H1 Z305 F1800 ; move Z up stopping at the endstop
G1 Z-5 F6000 ; back off
G1 H1 Z10 F360 ; home z again
G90 ; absolute positioning
G30 ; home Z by probing the bed
that seam to work
