Im trying to test a post processor for my DMG DMU103V with 840D control. I can run a few lines then any axis movement causes a 10720 error. This a software limit error somehow related to the zero offsets. The part WCS is in the middle of the table so theres no way its close to any hardware or software limit. Any suggestions on how to clear this type of error? Is it somehow related to some global Machine coordinate?
Heres a pic of my workpiece limits. Seems kind of large. I didnt set these except maybe by accident. Seems like plenty of room.

Same error when trying to run in MDI. Heres the program. This post is supposed to be for a DMG DMC63V with 840D. Also error is in every axis ie: if I remove Z moves, error is in next axis, either Y or X, whatever is first.

Rube siemens mistake, I used base zero to set my WCS at some point in my first attempt at setting up tools and work offsets. I didnt realize that base zero is siemens speak for machine coordinate system. I see that every 840d seems to have a different way to reset this usually involving setting parameters, but on the DMG its just a matter to selecting "base" in the scratch window and setting all the axis to zero. I had the z axis off by about 18" so it gave Z errors when trying to run a program. I reset and now I can run programs fine.
