I have been trying to dril holes into a spoiler board.
I have mounted two one on top of the other.
I set the work zero correctly at 0,0 and using a piece of paper drop the millend until it just grabs the paper.
I then set this to be the work coordinate 0,0,0 and start the spindle.
Subsequently the Gcode fails as soon as z goes negative (first plunge) with a GI/G0 alert saying I am outside limits.
When I start the spindle and ask to drill below the 0 height using the console buttons (-05mm) it fails again.
What am I missing?
Thanks
