Hello everyone!
Sry if this was maybe asked before, i couldn't find it...

1.) On my cnc lathe i would like on M6T# my spindle continue to spin and not stop when tool change
2.) I would like to slave Y axis to Z axis with using custom macro

I appreciate your knowledge in this

ok slaving Y to Z axis would be unnecessary, ill use post process for this.
But spining spindle on M6 Tool change is still reasonable for cnc lathes

Check the M6Start.m1s module in the macro folder, that is where the spindle will be stopped, remove the command and save the macro.
