I am having a similar problem to someone who posted a couple of years ago but no one responded. 
After Referencing XY andZ axis to their home positions, I create a G 52 work offset on my material. All works well as far as G 52 work offsets, and the referenced tool going to the G52 zero position when I select "Go to Zero".  But as soon as I load g code from BobCad and or some of the Mach 3 Wizards, some how the tool offset gets dropped and if I don't stop the Z axis it will go all the way through the machining wax I am playing with. I have already ruined a diamond tipped engraving tool as a result of this.  I have checked and rechecked the g code and BobCad says the G code is fine and that it has to be a Mach 3 setting some where.  I cannot figure out where. 

I would really like to get this cleared up so if someone could please call me or give me a number to contact you I would appreciate it a lot.

I understand there will be a $45/ hr charge.

Further to my request for phone support, please find a G-Code file generated by Bob CAD/CAM for a simple 4 letter engraving.  This program is the latest one that I have tried and which will bury the tool into the material and which turns off tool offset.  I figured that you would want to see and example of a program that didn't work at some point.
