Hi,
Just started milling on my newly cnc'd X2, I have a small piece that I created in GCAM (using EMC to drive the steppers).
What I'm seeing is on the y dimension the part is .020" to small and the X is .010" to large.
I have what I believe is very good repeatability, the cuts are all nice and lined up and I can run the program again with very similar results.
I'm using the stock screws at this point and have taken account of the backlash in EMC, could my dimensional discrepancy be from a incorrect backlash setting?
on the Y I'm trying to take .0105" off each side of an .375" wide piece of stock, it looks like the front cut is deeper than the back cut.
and on the X its the opposite, left (start) is shallower, right is deeper
any ideas? :drowning:
