General Mach Discussion / Re: New to CNC cant get motors running

I have set the motors to 262.5 mm/min and 0.5 seconds.
I have not changed the psu settings but the stepper drivers are getting 24.2volts.

I have 2 x 280oz in and 1 x 425oz in motors with a 24volt 8.3 amp psu.
 My tests were with only motor however I have just remembered I have loaded new software and I havent set the motors up.

Steve
I have got hold of an oscilloscope (im not a good driver) however I get square waves out of pins 2,3,4,5,6 and 7.
Where to next?

Thanks Hood, noted.

I have swapped computers with new software and I now get 8 leds lit in port1 pin state.

I will see if I can find a resistor and led.

Hi Steve
Just about ready to start trying things.
I will need to go and buy a relay to test with or could I use an led?
I am going to try another computer first I never really trust laptops plus they cost more to fix.
I'll let you know.
Apart from one motor to test with, I finished assembling my mill this morning, only one mod to make, but its useable.
So its not all gloom and doom.

I dont seem to be able to send it as an attachment. Is there another way?

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.

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

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.

General Mach Discussion / New to CNC cant get motors running

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
