General Mach Discussion / Coming out of jog error

« on: August 08, 2011, 12:30:22 AM »

I jog back a little and then forward to take out any backlash. I set the dial indicator to zero and push the DRO button to zero it. I type the command x1 and than x0. The indicator reads about 70 for a backlash of somewhere around 0.03. I didn't touch anything, just typed again x1 and than x0 and the dial stayed at the same place, about 70. I did this a few times, the typing of the command, and the dial stayed at the same place.

I repeated the whole above procedure with the same results. Next I typed x -0.1 and than x0. Made sure DRO and indicator where on zero and typed x1 and than x0 and the dial stayed on zero, no backlash.

My question is: why coming out of a jog it gives me a backlash and when typing the commands I have no backlash, nil.

General Mach Discussion / Axis stay short of where they should go

I'm sure that the problem was answered before but I didn't know what catch-wore to use to find it.

If I give an input, lets say x2, it will only go to 1.989 on the DRO. If I than give the input of x0 it will go to perfect 0.000. This error accumulates and make the circles be not round. I can't compensate with backlash since it's not the machine that is the problem, it's Mach3. The same problem is on the y axis too. Did I forget to make a setting somewhere?
