General Mach Discussion / All screwed up?

« on: December 02, 2007, 06:11:19 PM »

Mach3 is all screwed up.  I'm running a Sherline 5400 CNC mill, and a XP Pro computer. When I move 2" according to the marks on the X axis, the DRO in Mach 3 reads 31.8700. Mach3 is set to Inch. I tried to cut a circle but it ended up being about 1/4" dia. instead of 2". Any idea's as to what setting may be screwed up?

General Mach Discussion / Z axis going the oposite way it should.

« on: October 23, 2007, 08:09:34 PM »

My Z axis goes the opposite way it should, I always have to switch the values around to make the code work. Can this be fixed in Mach3 or is there something I'm doing wrong when I set up my CAM program to make the G-code?

General Mach Discussion / Mach 3?

« on: October 16, 2007, 09:28:20 PM »

Just got my new Sherline 5400 CNC mill today, tried to run it with a demo version of "Table top Machine shop's" Mach 3 demo program. I can't figure out how to use it for the life of me.

How exactly do I use it, I can upload the g-code but can't figure out how to make the machine move. Is there some kind of thing with the demo that wont let you cut? Or some kind of initial setup I neglected to do?

HELP!
