New to CNC cant get motors running
« on: December 13, 2007, 03:40:30 PM »
Hi
This is my first CNC project and I want to use mach 3 to run my x 2 mill, I have built my own controller box keling stepper motors and drivers.
My problem is I cant get the motors to run.
I switch on, the motors energise as I cant turn them.
I have set up the motors correctly as per the video tutorial for setup and trouble shooting.
I had a charge safety pump (cnc4pc) but I have disconnected it.
I have no e stop/limit  signals on the diagnostics page.
I have checked my wiring about ten times.
My thoughts are that either the breakout board is not working  (cnc4pc - C10) or my laptop controlling it is  not working properly.
Another thought is the breakout board is too close to the psu.

Can anyone help please.

Clive

Is your port enabled under ports and pins? Is the port address correct?
To test the port go to config - ports & pins - Input signals - automated setup of inputs and trigger the inputs

Port is enabled and the port address is correct.
I understand the automated port setup but how do you mean trigger the inputs,
I really am a complete novice.
Thanks so far.

All you have to do is select the input you would like to set up from the drop down box eg: x limit switch ++ click on autoset and then press the limit.

I have done that the limits work, but the motors dont.

Do you have power on the step and direction terminals and is the polarity correct?
If so check the pulse train from Mach with an oscilloscope

I have 5v power on step and direction and the polarity is correct.
Am I meant to see anything in the "Output signals current state" in the diagnostics window because I dont.
Also I only see 2 green leds (5 7)in the port current state.
