hey.. waiting for my machine to get fixed buy i noticed something odd happening when i import g-code into the Mach3 on this machine... everything is almost double scale... not the normal 10x scale from mm to inches, but its like a prop scale of 2x..
If i take the same mach3 gcode file and load it into another machine here, the scale is perfect, so the problem seems to be just the way this machine is configured ( from the factory )
any ideas?
I am far from a Mach3 expert. But did you download the manual for Mach3 ? It is a bible for those of us that aren't super fluent with it.
Also you can PM GER21 on here, he is very fluent with Mach3.
mm to inches is a factor of 25.4Quote:

it could be the steps are set wrong, or just a simple unit conversion, or maybe mach's scaling is on, though you would see that in the mach screen next to the axis positions.
I'm having the same problem. It's not mm/inch issue. Motor tuning is set up correctly. I have a varience of .017 inches when running the following drill file below. Thanks for any input.
