Hey guys, Mach 3 runs great for me with 1 exception. It does this every time. I always need to zero the Z axis a 2nd time. For example, when I touch off the top of my work piece, zero out Z on the DRO, then start the run cycle, Z will go from about 100.000 or so instead of from its relative location from where I touched it off. I repeat the whole process again, touch off, zero out DRO....etc.. and it's fine. Always takes that 2nd time.
Any ideas on why?

Tool offset being called? Work offset being called?

Hello Hood,
Thanks for your quickness. I will check those tonight after work. If any value is in there, I'm assuming I want it zero. I don't want offsets. I place a thin piece of paper under the tooling, lower Z until I can't move the paper and zero it out. Just tedious when I have to do it twice.
Will post back later.

It could be for example you have a tool offset in the tool table and your code is calling the tool with the offset. For example you may have an offset for tool 1 in the table and your code is calling G43H1.
Likewise it could be a work offset, Mach usually defaults to G54 when you start but your code may be calling a G55 offset.

Well Hood, that's exactly what it was. A tool offset. It was at exactly 100.000. I must have done this awhile back by accident. I have no idea why it would be there otherwise. All is good!
Thanks for the help.
