I recently re-engineered my entire machine adding another rack the to the opposite side of the table and mounted a 4th axis to slave with Y. Using mach 3 I was able to slave the 2 axis together but now when the machine jogs on the Y axis Y2 Servo makes a decently loud buzzing noise while trying to hold position with Y1 (this action causes the table to shake until it reaches square.) This problem is causing circles and most other shapes I would cut to have a wavy rough cut and the only way I have been able to avoid that is to slow the machine wayyyyyy down and do multiple passes and still getting some interference and makes even my fast travel have to be very slow to get a semi accurate shape.

Sounds like either a servo tuning issue, or the gantry is so far out of square that the servo is struggling to keep it square?

gantry is pretty square. I'll try and tune the servo some more and see if I get any better results.
