Quick update.
I did try turning the balance on my west amp drive per C. Radek's
suggestion, but I will admit I'm chicken to turn it too far!! ughh... I
turned about 1/2 turn in both fwd and rev directions and didn't see any
change. Considering its a 20 turn pot, I suppose I should at least give

eem right?
Lastly, to beat a dead horse, I thought the higher resolution linear scales
would be easier to mount because of the existing bracketry. To add the
rotary encoders, I need to add mounts to the end of the ball screws or
backs of the motors. Maybe I'm being dumb here...

Seb,
I had that graphic taped up on the wall at my last job:-) Never did use
it, but thought it was cool.
Anyway, after looking at it again, none of the standard I/O outside of

Alex,
Yes, the application is industrial grade, but it is quite simple (2 axes of
motion). I only need 1 modbus network to two temp controllers. Since
there are 2, that rules out '1' RS-232 network, but I can use '1' RS-485
network. Or Seb's USB setup would work.
I did see on the mesa site the

I'm looking at controlling a X-Z gantry system w/ LinuxCNC (well really HAL

How do I set up my servo enable and spindle enable (?) so that I can run
the mill manually, but still control the VFD via LinuxCNC? I'm not that
familiar w/ the actual AXIS interface and unsure of all the features it
has. I know I can add in features either through python widgets or
