running mach 3 with a usb to parallel adapter

Kendrick, I do not think your spindle is DC, changing the frequency on your vfd will change the spindle speed, so it must be a 3 phase spindle motor. Remember what I told you last night, spindle speed is pairs of poles x frequency,
ie vfd frequency say 400hz (cycles per second) x 60 (seconds to minutes) = 24k RPM. This is a little higher than the actual speed due to slip, but is near enough for what you need. Ihope that makes sense. G.

Easy to check Kendrick just take the connector off the spindle and if it as 2 wires it's DC, 3 wires it will be VFD/3phase like Geoffrey says. Looking at your other post I agree with Geoffrey it looks like VFD control panel.

Fr the power problems with the usb what about a powered hub then the usb power is not coming from the laptop.
The spindle has 4 pins coming off it more than I would expect from DC maybe brushless with a backemf sensor wire.

Kendrick, you DO NOT have a DC spindle. G.

I have a UC300 which I've used with Mach3 and was better than just the parallel port on the PC. I now use it with UCCNC and it's another big step up from using it with Mach3. UCCNC and UC300 are designed for each other, with Mach3 you're relying on a third party plugin sitting between Mach3 and the hardware. UC300 is a good option if like me you want to add more sensors like probes and FR override control. The other advantage is you can move beyond WinXP/7 on your controller PC which when you also use it for running Vectric software is a huge advantage. Running mine on a Win10 machine and it's as happy as Larry.

Can you run a UC100 with t2 laser/CNC Software? I can't get it to comunicate wih the USB on my notebook pc! Please Help.
Thanks in advance!

It will only work with Mach3/4 or Uccnc.

Thanks, I tried hard to get it to work! Would you buy Mach3 Mach4, or UCCNC Software? I would like to run it unders windows 10 ona newer P.C!
Thanks again for your help!
