Mach3 - auto tool zero not working with a certain router bit
« on: March 26, 2020, 08:50:34 AM »
Hey guys, I've been fiddling around with a CNC router for about 3 months now and just stumbled upon a problem.

So every time I try to do auto tool zero with tool number 3 (3mm end mill), it works like a charm. When I try to do it with tool number 4 (6mm ball nose) the machine stops 7-10mm above the plate.

Would love to try your solutions. Cheers.

It could be the G31 command in the macro, it needs more Z movement.

Yep, Z movement was set to 200, thanks.
