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.

You could just use a LED in series with a 220 ohm resistor for 5V

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.

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

Clive

The forum will only accept an attachment once so if a file by that name has already been posted it wont let you attach it again. The way round this is to rename your xml before you attach it.

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.

Thats great ! your break out board is working.
Now check your power supply - maybe the stepper drives are pulling more current than it can supply.
Connect only one motor with no load.

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.

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 cnc4pc c10 breakout board and I have 5v on the enable line does anyone know if I need to set up anything in mach3? There does not appear to be a pin number to set it to?
