I have a 3 axis router (dual X) running ballscrews.
It has work fine for a few years now, but started to cut off-size, and in consistant
Doing a steps/mm check over 1m, and accuracy is better than 0.5mm - This is repeatable
However, when I try to cut simple squares 25mm, they measure 25.6
If I do parrallel cuts at 25mm spacing, some are 24 some are 26 (almost like every second cut is offset by 1mm)
Re-test the 1m and still accurate.
This is new, and Im totally confused !
Can anyone help please
Thanks
Drew
