I am not sure how to set up a system I am working on.
Essentiall I am revamping a large old stepper motor 3 axis mill used for sheets of plywood.
I am using a DMC-1886 and some Parker BE34 Servomotors. I have 2 of them on one axis that runs a gantry over the table and are connected directly to gears and racks on each side.
Should I be using electronic gearing to control one and then the other as a slave?
Yes, you use two separate axes on the Galil, then gear the axes through electronic gearing. You want to gear off of commanded position instead of actual position. See the GA command in the command reference for details.

Ah, perfect I thought it would be something like that.
Now how do I go about tuning, one then the other? Because when there running together each will be sharing the load, so it seems like I would have to tune them at the same time?
Get them tuned individually, but then back off the parameters by ~20%. The load should be stable at this point and you can then tune when the axes are running together.

I have another issue. I can servo my motors currently and it seems i can successfully change the PID values also. However when I attempt to tune using the WSDK I get no movement.
When I attached it to my gantry setup, the system vibrates extremely violently at a nearly deafening tone.
