Fair enough. I was assuming it was pretty close and you were just getting the last bits of skew out.
Depending on how your gantry is attatched to your bearing blocks you could, once you new the error, just lossend the bolts and advance one side or the other using the steppers/ servo independently then snug up the bolts again and recheck. Probably easier with a dial indicator though.

Now I must hurry up and get mine finished! |
