General Mach Discussion / Re: motor tuning
« on: November 06, 2006, 06:53:02 PM »
thx for the fast reply guys.....
My unit is a ballscrew driven cnc router, I am using a xylotex board and Mach3 software.
As for setting the values I did that manually...basically I kept on adjusting the value untill the circle's ID matched (using calipers) what I drew in the software, i.e. ID 4.015". At that point I assumed that I was done calibrating/tuning the motor... the number came out to be ~6400 for both the x and y axis
I haven't used the auto steps per unit botton, I will try that tonight and see if my number and the number mach3 spits out are the same...i'll also try to put the unit in sherline mode and see what happens.....
As for backlash I'm not sure how I check the value of this.......I do notice some backlash thought I assume its about 4-7mils, 0.004-0.007", but I'm not sure....any good websites on how a non-pro can learn how to accurately figure out the backlash of an axis??
thxs a bunch guys, I'll work on it tonight and report my findings...
