Can anyone help me with a small problem with MachTurn ?
Whenever I try to enter a zero in the Z axis dro, it won't do it, it just moves on to the "code" screen and it becomes highlighted ! In other words I manually move the tool to the end of my stock, sometimes the "Zero" button is there, sometimes it's not, I then click inside the dro box to highlight it, enter 0, and it just moves down to the g code window.
I don't use mach turn a whole lot so can't figure out when exactly this started. I don't want to do a re-install as I have a load of stuff set up for my mill that I don't want to lose.

I think you need to zero the DRO on the manual tab. Make sure pgm coordinates are selected.

Thanks buddy, I'll give that a try.
