I'm just getting to resetting my Partner 1 mill back up right after the control lost it's battery. SportyBob reconfigured it with the latest version that my machine will accept. He did a great job, BTW! Anyhow, I like to use a tool setter and have written a couple of programs to use M codes to set my tool length and part height. On the old version of the control this worked great but I ran into a couple of issues with how the control handles codes. I worked that out ok but now I have found that my machine Z0 isn't at the home position! It's at -9.1688". Home is positive by that much and anything below is negative. This wasn't a huge issue until I tried using a long drill that was above this zero location.
Why isn't the home position 0 like before and X and Y are? How do I get it so that it is? I've gone thru all the settings and parameters a couple of times and can't find how to fix this.

Thanks for any help!

Mike
