General Mach Discussion / Re: spindle problem mach3 mill and cnc4pc c6 board

I thought i would post the final resolution here so everyone can see.  ultimately i found this problem after putting a scope on the input.  the signal wire from the parallel port was picking up noise and triggering the VFD at around 12 hz and this wasn't allowing the spindle to shut down.  i ended up putting a capacitor across the input to the board to ground to filter it.

the C6 board from cnc4pc tells you to use the Step/Dir motor option not the PWM motor option.  i will go through it again today and see if i can find a problem with the VFD settings.

Hood,

thanks for the post, but yes i have checked the vfd parameters and they are correct.

i finally got my spindle wired with a vfd and 3hp motor.  i went to try it out and after some fiddling got it working.  i can vary the speed and i can go forward and reverse however the spindle doesn't shut off when i program an M5, M2, or M0 command.  it will slow down but the vfd still runs at 12hz.  i don't understand why this isn't shutting down.  i have spindle setup on port 16 for step and port 17 for direction.  i'm not using output 1 and 2 i'm using the spindle setup under the motor connections.  any help is much appreciated.

thanks

jerry

Hood,

how many outputs did your PLC have and how did you time the circuit?  did you add positional switches to let it know its selected the right tool?  can you recommend a PLC or let us know which on you used?

thanks

i agree a roughing profile is really missing.  this should be part of the actual MACH3 install package and not an LCAM based setup.  ideally you want a single line G code that can rough a non standard profile, not a 1000 lines of code spit out of LCAM.
