Got it! turns out the roadrunner gcode is made really small.  My files are attempting to cut the correct size now. Machine is stopping on some gcode, not sure why.  Time for another thread!  Thanks for the help

Also tried a file which I had made in Vectric Aspire that is done in MM, still same result.

Using MM, its a CNC 3040.  I had been using it for about 8 months with TinyG and Chilipeppr.  TinyG just died yesterday, they had a bad batch of them released with incorrect lock bits, so will be sending back to have reflashed.  I bought an all in one breakout board and driver system a while back, and figured this was the perfect opportunity to covert over to Mach3.  The system is this one http://www.ebay.com/itm/Professional-4-Axis-CNC-Stepping-Driver-TB6600HG-Box-Set-LCD-Display-Keypad-5A-/401278390859?hash=item5d6e0e524b
All axis jog properly and have been through the calibration, its just when trying to cut anything is (really) small, maybe 10mm for the roadrunner gcode.  Could it be something with steps?  I have it set to 1/8 steps although it could do 1/16.

I have setup Mach3 and completed the autocalibraton in the settings screen.  I have it dialed in and is pretty much accurate at 408 steps per unit.  When I try to cut a test such as the roadrunner file, it is only about the size a dime smaller.  Anyone got suggestions?
