General Mach Discussion / DRO error in mm

« on: May 24, 2009, 04:40:36 PM »

I have been working in inches for some time and the DRO's always read exactly what I commend.  ie: X1.2345 reads X1.2345 after the move.  I just switched to a project in mm by starting my code with 21.  I set X=0 and then moved X=10.  The DRO reads X 10.0013.  It happens in the Y axis also - and the incremental change is not always the same amount.  ie: X54.0635 becomes X54.0639 but
Y29.93565 becomes Y29.9371.   Can anyone tell me what the problem might be.

Thanks

General Mach Discussion / Mach 3 Subroutine Codes

« on: November 06, 2008, 09:47:45 AM »

I'm new with a Taig CNC, Mach 3 and BobCadCm to learn.  I notice that the last line of any code does not show in the Mach 3 Program Run window.  In fact, when I write a subroutine starting with M98 and ending with M99, the subroutine runs, but the program stops at the last line in the subroutine - and doesn't return to the program.  I found that if I added another M99 (one after the other), the code now shows in the window and the program runs correctly.  Any help would be appreciated.
