Hi,
Sounds like your steppers are missing steps. Try tuning them to half their current speed and acceleration and try again.
Disable and/or set the backlash settings to zero and leave them there. They are just confusing you. You need to be able to
MDI 10 inches the the left and then 10 inches to the right and come back to the same location within the bcaklash of the machine,
which should be minimal.
If the backlash of your machine is 1/16 to 1/8 inch then fix your machine. Expecting software to overcome that sort of lash is a fools dream.

It will be off about 1/16 - 1/8 of an inch. I continue to do the same and always enter 10" and it continues to get off more each time.
