so new problem today. started machining a part yesterday. noticed that table was off a couple of degrees cutting a taper over the 12" length i was cutting, around .06" difference from front to back. switched pallets and dialed in other side and it was fine. took off pallet that was 'out', cleaned bottom, put back in and dialed it up and all seemed good. go to run program this morning and table 'out' again. did a pallet change and measured and all good. ran program, cut b0 side fine, rotate to b270 and again i'm getting a taper, dial table and it's way out. do a few rotations in mdi and constantly out of zero. turn off/on, home everything, do pallet change and table is fine. made a mark on the bottom of pallet where it rotates and marked zero. rotate 90 degree and table out again, brought back to zero, mark lined up but dialing in table its way out again! checked in x and z direction and both ways the table is not square. any thoughts???
