That's awesome. I am trying to get a PMDX-126 and UC400ETH up and running. I use Clearpath Brushless Servos with integrated drivers, which are amazing compared to steppers. Mach3 CV is a joke. How is UCCNC CV and Trajectory?

You are running clearpath servos and you are asking what motors and drivers you need?? lol you have no concerns there as long as they have a step/direction interface put it that way.

uccnc cv and trajectory is excellent. You need a faster pc than you would usually need with mach 3 but the reason for that shows.

Any breakout boards which are printer port compatible, has printer port pinout should work.
What input signals does that Clearpath servo supports? If it supports step and directions then it should work with the UCCNC.

They use step and direction. They are designed to be a drop in replacement for steppers. I like the integrated drivers and the easy tuning program they have. They also have hard stop homing limits which is a good feature. I've been running them for a couple years problem free on 2 of my machines.

Id be tempted to sell the pdmx on personally. its ok but lacks descent isolation and dont really gain much from it using uc400 and not an ess.

I use a cheap and cheerful HGO8. Not a widely known board but they have excellent isolation infact probably the best ive seen on bob and ive tested them plenty having 3 of them, the boards are pretty much populated just with large 10mb/sec opto isolators which when using a uc400 is all you really need from the bob besides the breaking out obviously . Ive fried channels on them, just swap channels and carry on . slightly lack in inputs and relays but they are that robust if i needed more id just run two which you can do with the uc400.
