Thanks guys
I think this is a backslash issue :-(
Did some tests with a dial indicator - have observed funny thing.... suppose I jog the x axis to the left - zero mach x axis and zero the dial - when jogging to the right - the dial initially shows movement to the LEFT and then it starts to move to the right- backlash is about 0.45 mm
I have Kerk motion leadscrews with anti backlash nut ?? have no idea how this is happening - when power is OFF - I can see no slack movement between the motor shaft-coupler and leadscrew.
Tried to fiddle with the backlash config - shows better results though
Any ideas how to get rid on minimize the backlash?
Cheers
Isaac
