Brian:
Just downloaded and ran 3.042.015 and have the same issue previously reported regarding 3.042.004 (see below).  The part was cut correctly, but looking at the weird numbers in the Tool: Table Display screen was really disconcerting.  Have gone back (again) to 3.041.
Previous post follows:
Downloaded and ran 3.042.004 version and had nothing but problems.  Code that ran perfectly in version 3.041 would not run without problems in arcs, etc.  One thing I noticed on the Diagnostics screen is the abs max x, y, z were all out of proportion to the drawing in the code in mill mode.   The figure in the code is 11.5 by 5.5 inches - the Diagnostics screen showed the max to be like 116 (somethings).  Yes, I copied my old xml file into Mach before running the code.  Yes, my native limits were in inches.   I had the same problem with another code.
