i'm in a spot of bother with the mach3 spindle control. i have wire the BOBto VFD as follows,i have set up the various ports, pins ,outputs as follows, when i turn on m/c the spindle starts up and i can't turn it off until i do a reset from mach3. i can then go to the output signals tab and turn on active low for output 16 and the spindle will turn on. i can toggle it on and off from this tab. i have tried to set the various related ports and pins, on/off, but i still get no joy. any help would, at this stage be appreciated

well , i have at least got the spindle running and stopping (the correct way)) from the reset button in mach 3. i emailed Gary @ ZAPP and apparently i need to wire in 10 v from the VFD to the BOB. i'll give it a go.

No using Reset is not the correct way to start/Stop spindle.

I also think Gary as got this wrong. The 0-10V signal is generated by the BOB you don't need the 10V from VFD.

I'm a little busy at minute but I will look at this for you later.

Ok well looking at the manual again then Gary is correct and you do need to supply the Bob with 10V for speed control, which is poor IMO but not a problem.

Regards the Relays I think you may need to change SW1 to Off and work in Enable Mode not Charge pump mode for the Relays to work correctly.
The manual isn't very clear on this but that's what I think it's trying to say.? . . . . Give it a try and see what happens.

The way the Spindle should Start & Stop is with issuing M3 for CW, M4 for CCW and M5 to stop from G-code or MDI. Or with on screen button or F5.

I think the service is slipping Dean,

It's not my fault Pizza man is slow driver.!!!!

Do the relays have NO & NC contacts and you have wired to the NC contact.? This cause spindle to start when Mach is reset because the Enable will activate the outputs and because you have wired to NC the circuit is made straight away.!

i changed that and now it works correctly but the moment i take mach out of reset the spindle starts and i cannot turn it off . the spindle CW F5 button has no effect and i can only turn it off by putting mach into reset. i cannot adjust the speed also ii appears to run at top speed.
