Thanks for the great info Tweakie. I would be using Powermill or MasterCAM. Would that satisfy the computation of the kinematic motion requirement before processing the G code? Checked out the work, looks very promising. Hope he keeps it up. Hopefully a version for Mach 4 will pop up soon. I'm interested in the Industrial version but if I could get away with Mach 3 / CAM combo that would be great. This will be a project but hope to usher the machine into the modern age soon using this software (it was built in the early 90's). Is there anything that I could buy ahead of time to prepare the machine for a smooth transition to the software? Comms, USB conversion, hardware. etc?
Thanks so much.
