I recently finished converting my mill to cnc. I am having a issue with dro not reading correct. When I jog the table 1" by measuring with ruler, the dro reads 4.043. The only way I can the dro to read correct was to set the steps per to 8088 and it close, not perfect.

Setup:
520 oz on x and y
1605 ball screws on x and y
Kl8056d driver

906 oz on z
2505 ball screws on z
Kl8070d driver
