Bought a DM2800, original control. It initializes, takes program via keypad input, runs great. No intentions of replacing the control (yet).
Next step: download program from PC, then "drip feed" lengthy CAD/CAM generated code. I've read all related posts, but haven't seen this one resolved. Trying to avoid pricey DNC software but will consider recommendations. When it's working I will follow up with specifications including any custom code, and some CNC programs (I have an NAS-979 circle-diamond-square program ready for prove-out).
TIA, Steve
