Knowing the prices AXYZ charge then you'll probably find it's cheaper to convert to Win PC based Ethernet controller like UCCNC and Motion Drives controller like the UC300ETH or AXBB-E Depending on the I/O requirements of the machine. Which pacer model is it.?

It's usually not a massive job to convert for a machine with standard I/O setup ie: E-stop, limit SW, Home SW, etc, and depending on control box layout, wire lengths, etc can be done in few hours.
If the machine is fitted ATC fitted or Vac bed etc then it gets slightly more involved and requires Macro's etc but can be done in the Day.

UCCNC software is very easy and nice to use with plenty of features to make life easy and can be made to control just about any machine. The hardware side is good quality and the Ethernet controller is Rock solid.

If you want to Upgrade the controller then drop me a PM as I can supply you with both models of the controllers mentioned above and the software license.
I'm also more than happy to offer any advice on installation and setup.
