Issue with step servo setup - x-axis cutting skewd

Please see attached.

No, the other axis backlash setting isn't working either.

John,
I think the guys were getting confused. I went and tested as you indicated with setting the jog to 0.001, when i changed directions it would swing negative ~0.004 the other way. They had to turned up the backlash way too high. So by zero'ing it out and watching the needle, with backlash = 0, it took basically two jogs to make the axis move 0.001 in the opposite direction of motion. With the correct setting now it seems to be compensating correctly although it still not 100% perfect. I think they were trying to dial it in with too large of a step size or something not sure. I was going to test cut but unfortunately it looks like nitrogen likes to bleed out of bottles, both of our tanks are empty now. Much appreciated though.

For what it is worth I use a 5i20 and the backlash comp does work.
To check I use MDI moves.
With the backlash comp off...
First a large negative moves at a slow speed say g1 x-1
Then a positive move g1 x1
I then set my dial indicator at 0
Then a positive move say g1x1.025
Then check that the machine moves .025 to check the scale
If that is OK then g1 x1
Read the dial indicator and any difference from 0 is the backlash for that spot on your machine, it could be different in different locations in which case you may want to look at a compensation table.
Put the backlash comp back on with this number and try again, should be OK now.
