Title: Go to Zero not working Mach 3
Post by: mpoling on November 13, 2018, 11:03:11 AM
Hi all,
Having a problem with the Go To Zero button in Mach3.
It worked up until about 2 weeks ago.
Now when I hit it, the Z-axis lifts until it hits the limit switch, then triggers and stops.  It never homes X or Y.
I have changed nothing and no updates have been done.
Any ideas?
Thanks
Mike

Check your Safe Z settings in Config > Safe Z.

Was set to Machine Coordinates instead of Work Coordinates!  Good call!  Changed it to Work Coordinates and its all good.

Thanks!
Mike

It's better to be in Machine Coordinates, provided you have a Z axis home switch, and use it.
