The plasma cutter I am building has two servos for the x axis. The problem is that they are not spinning at the same speed. I can't seam to find the problem.

This is what I have tried so far--

- the settings in the VSD-e servo drivers are set the same
-I have Mach 3 set to slave X axis and A axis together
-I have the motor tuning portion for mach 3 the same for both x and a axis

Both servos are spinning the correct direction.


Any ideas if this is a servo driver setting problem, a Mach 3 motor tuning problem, or something else?


Thanks for the help
