  • CNC Retrofit

    I am a CAD teacher at Traverse City Central High School.
    I just picked up a CNC Hartford mill, with no power supply and no controller and missing one stepper NEMA 42 drive motor. I had looked at a controller card from Machine Master for $1995 but that was only the PC card. It seems like such a shame to go back to turning cranks when I have access to Master Cam and all it's capabilities.

    I just found some info from Flashcut CNC, they have size NEMA 42 stepper for $595 and their 12amp 3 axis stepper drive box goes for $4295. I don't think I am ready to spend that kind of money to go to CNC. I would very much be interested in any suggestions anyone might have?
    Thanks for any help.

    Dear Sir:
    Depending on how you feel about do-it-yourself projects, there is a lot you can do.
    You would need:
    1) DC Power supply, parts cost maybe $300
    2) Stepper motor, cost around $300
    3) CNC controller, cost from $50 to $1000
    4) PC, used, cost $100
    5) Cabling, cost $100
    So maybe $1000 would get you a CNC!I would be pleased to discuss thie further if you wish!

    PS: Do you have the stepper drivers, (3)?
