After three weeks of frustrations and lost production, and a burned out controller board, after doing more research on controller hardware and software, plus a suggestion from Louie Atienza, am focusing on this:
CNC Control Software | Flashcut CNC
Have spoken to Ron and Anne at FlashCut and have downloaded the demo version of the software and am going through setting it up on my work station.
I like the integrated hardware/software. The manual is well written and has a user's point of view.
Yes, it does cost more than a MACH and Rockcliff or MACH and Gecko set up, but how much does lost production cost, being from a CNC not setup or functioning, and not being able to work on g-code to cut dovetails and box joints, which was one of the main focuses of this build.
Senior management has raised the usual issues, but in the end, especially if there is a dollar sign associated with an activity, I suffer no matter what I do, so might as well have fun!
