1. Some general background on the machine how were they and can you still get parts and pieces for them? - Parts and Smarts, Ebay, Me - I have a used Dynapath 20 control in a box, servo motors, monitor, etc.
2. Does anyone have pull studs out there or know a part number where I could order them for the cat 40 tooling ? - Ebay, you need the ones for Fadal / Mazak (short ones)
3. Are there manuals both for the control and the machine available out there? I have manuals and documentation for the Mill and Dynapath 40 control.
4. was the machine worth the investment if it is operational? I LOVE my J425 and the Dynapath control!!! At first I was unfamiliar with the conversational programming, but it is quick to learn and after I got used to it I much prefer it for most basic programs. You can still run regular G-code programs.
