    when I looked into it the cost was usually around $18-20 per scale to upgrade to a 1um scale. Can't see too much point on a mill, but a good option...

    can you program a VFD for the equivalent of rapid feed? ie. a momentary button that bumps the frequency up to 90 or 120Hz for short periods? That...

    that's a cracking offer. If Radkins doesn't take you up on it I have a MC2100 I'd be happy to swap if you could use it.

    the bearing shields are what keep the oil in and (most) of the junk out, sounds like your rear bearing may be missing one (the inside pulley one?) or...

    You need a PWM signal generator that puts out 0-5V at ~20Hz (50ms signal, that's 20Hz I think) to one of those plugs on the board. You need 3 wires...

    that's definitely a PWM controlled board. Given that you already have it and you know that it's sized right for your motor, I'd suggest finding a PWM...

    or get an MC-40 or MC-60 controller. Both work well, though the MC-60 can be made to start at the same speed after being turned off - the MC-40 has...
