Hi Ian

Thanks for the quick response.

Correct, the machine is SLOW and will remain so. The aim is to replace the current faulty tracing system on it.
The current motors on it is a small 19v DC pittman motor with a huge reduction ratio. Most likely more than 200:1. Replacing the faulty motor is around $700 before shipping, taxes and freight. For that price I can go a long way towards CNC.
The machine will not be doing anything else but what it has been doing. Cutting very slowly through thick metal.
