YAHOO I got it working!!!!! No more crashes!
I figured out what you meant about re-zeroing the work co-ordinance after a run and yes I was having the same problem. But now it is solved along with my original problem. This controller does NOT like going from work

co-ordinance

to Machine

co-ordinance and back again!!! To solve the problem I add G90 after every G53 (G28) and to solve your problem at the end of acycle, you need to add one at the end of the code after the final G53.
Here is the test code that came from fusion i'll highlight the lines that I hand edited.

Hi Glen,
cool that you figured it out !!!! You might want to report that back to the developer ... I can confirm on the weekend with my linuxcnc machine that this is not normal behavior.
