UPDATE:
I set origin position to G10 L2 P1 X-430 Y-400 and now it homes to bottom left correctly. However when clicking on laser position somewhere in the laser bed to move laser there, I get the following command:
ALARM:2
G-code motion target exceeds machine travel. Machine position safely retained. Alarm may be unlocked. (Right-click the ‘Devices’ button to reset the connection)
Op of nabij lijn 2:
Stream voltooid in 0:00
[MSG:Reset to continue]
Is there still a setting somewhere that needs attention?
This one solved as wel: cleared offset using G10 L2 P1 X0 Y0.
