Hi

My problem is - from recently, when i use "goto zero" command switch, my z-axe no more raise up to safe distance (+20mm) and then go to x0 y0 position, and then z0!
Instead of that z axe stay in curent (low) position and x and y go to 0.
- if z is in (minus) position, then movement crack my bit

How can I set this so before x and y go homing to 0, first raise z axe to safe heigh say (+20mm)?

thanks for help
