The Y axis on my Aciera F1 binds a little at the ends of its travel causing the dial to slip. I oiled everything, pulled the Y axis bronze leadscrew nut, and slid the head by hand to confirm free travel through the entire range. Feels pretty good overall.
I inspected the bronze nut thread, and reversed it (it has seen better days). With the nut reversed the Y axis travels its entire range better, but the dial still binds and slips occasionally (thereby losing its position and zero reference).
I took the dial apart, cleaned, put it back together, and adjusted the bearing plate to take up excessive slack. The dial still slips even though the grub screw is tight. Any suggestions what else I ought to look at?
A DRO would solve the problem, but I want the dial and leadscrew to work as intended.
