General Mach Discussion / HELP.........Motor Tuning problem
« on: February 11, 2007, 10:43:11 PM »
Hello,
I'm using Mach 3, and I've got a problem in which I have no
idea what to do......
My X-axis has been a little off ever since I built my small
router, I just never fixed it because it wasn't enough
to worry about (like 1/16" on a 29"span)
So finally I decided to fix it because I need to
machine some close tolerance aluminum parts. So I got
it accurate within a few Thousandths over a 29" span.
I figured the closer I had it over the longest span,
the smaller the margin for error on a shorter
distance. Right?
That's not proving to be the case though. Its actually
MORE off on a 17" span now (like maybe a 32nd) than on 29" (few thou). How can that be? Any idea?? In reality I need it closest on the
smaller parts. Thanks in advance for any help! I'm using a Ballscrew with Zero backlash by the way.
Best Regards,
