Here is a thread that goes over the broad details:
All of the original hardware could be used, but I opted for more powerful drivers while I was upgrading. I also wanted a contactor to make the machine a little safer. If my budget and cabinet were bigger, I would have put in more safety measures. The biggest lessons learned were:
- Don’t bother with the existing tool setter and probe. They do not play nice with a properly grounded machine - you WILL fry them eventually.
- The servo driver will need to be adjusted to be accurately drive the servo motor. If you need the settings, I can probably dig them up.
- The Langmuir cabinet is too small. Save yourself some trouble and just buy a new cabinet. I spent more time trying to get everything to fit than was necessary.
- The limit switch cable needs to be rewired to work with auto squaring. The existing takes too many inputs to work properly.
- Purchase the CHIPS probing add-in. The probing routines and work flow are a huge help.
