Hi, Im trying to get my shapeoko 2 CNC milling machine setup with Mach 3. I'm using a Gecko G540 and a UC-100 USB parallel port to USB adapter. When I run a test program of a 25mm square, the square comes out to 20mm. I tried using the G540 XML loader but the axis steps were way off. My current step per setting for XY is 40. I have to use the UC-100 because my PC is windows 7 64 bit which will not work directly off the parallel port. My question: is the UC-100 compatible with Mach 3 G540 configuration?
