Use the A axis. Set up both the X and A the same, and slave the A to X.

The only annoying problem is the wabble I get on my 36” long Y axis. As I said when the gantry is in the middle of the Y axis I get this annoying sound like “running gears with no oil”. The lines the machine draws at this point are straight, so it does not affect the performance – just sounds like a coffee grinder.
Does anyone have an easy fix for this?
The Y axis has a single Delrin nut (see attached pic)

Sorry Gerry dont know what you mean by "drives"
Motors are Keling stepper motors with 8 wires and wired as unipolar
The 3 drives for the 3 motors are Probotix http://www.probotix.com/stepper_motor_drivers/ProboStep/
I have set the steps on the drives to half step and in mach (steps per) to 4000
Hope that is what you want
