Part 2...

You don't say if you have also changed the computer, say to a Win 10 machine, or if you reinstalled Mach3. After proving that the UC100s worked, I then moved to the Win10 machine. Though the machine was bought used, it had a clean Win10 install so I could start from square 1. I installed Mach3 from NFS; then went through the procedure for transferring the machine setup files from the XP install. The setup is saved, I think every time M3 runs, in a folder called XML backups. These include for example all the ports and pins assignments. So you take the most recent known good xml backup and (IIRC) you just put it in the Mach3 folder to replace the one already there. When I did that an re-connected to the lathe and mill, again everything (mostly) just worked. All the pin configs were just applied to the new M3 install.

The one tricky problem I did have was getting my XBox controller working, which I find invaluable for placing the tool for probing etc. This turned out to be because the XBox plugin used some Microsoft components that were in XP as standard but not in later versions. They can however be installed from the Microsoft site without affecting other Win10 functions, as detailed here:
