General Mach Discussion / testing outputs on breakout card

« on: July 22, 2011, 06:48:46 AM »

Under section 5.3.8 of the mach3 manual it covers testing.
It tells you to go to the diagnostic screen
it is then possible to test each input by shorting to ground each input pin
on the breakout card and an "led" on the screen lights up.
That great for the inputs.
Is it possible to test each of the outputs one by one by tweaking something on the screen.
I have an led and resistor on each of the outputs on the breakout card.

General Mach Discussion / stepper signals from breakout board

« on: July 07, 2010, 03:39:10 AM »

I have downloaded the demo version of Mach3. I have set up the address etc. I have leds on the outputs of the breakout board.
I can toggle these individually by playing with the active logic level and they work ok.
when I go into the diagnostic mode and use the jog command the dro changes as one would expect but the
signals to the stepper motors never change.
What going wrong?
thanks
