  1. Re: Looking for parts to replace Baldor Smartstep 3 Controller board.

    Glad to hear you got the motion working. Having programmatic control over the spindle speed motor isn't really necessary for such a small mill...(I generally just run it at full speed and adjust the...
  2. Re: Looking for parts to replace Baldor Smartstep 3 Controller board.

  4. Re: Balfor NextMoveST PWM spindle speed control?

    Update, I figured it out. It requires a bit of circuit bending (remove surface mount resistor R29 to disconnect Pin3 of the optoisolator from the normal drive circuit, solder a 200-220 ohm resistor...

    Sticky: Re: Welcome thread-tell us about you.

    Hello, I just purchased a ScanTech 2000 Mill & Lathe (Basically a Denford MicoMill / MicroLathe). They didn't come with any software, so I'll probably have to wire up an interface directly to the...
