Ports and pins current state in Mach 3
« on: April 22, 2008, 10:44:07 PM »
? Can anyone tell me what I'm looking at in the diagnostics screen in Mach 3- ports and pins current state
I see 2 rows of 12 LED lights.
Obviously they represent the pins out of the printer cable.
But when I match it up to lets say a BOB how do you know which is which.
Is LED on the top left = to Pin #1 on my breakout board?

Please let me know,
Brian
thanks

Brian - I dont know - but yes - I was looking at the same display yesterday, thinking the same thing.

If you have a set of manual switches that you can access - e.g. your limits and your homing - then I would set them up as 10,11,12 and 13. If you then press them manually, in order,  you should see them light, which will give you an idea where they are. All the diagrams of the LPT1 inputs/outputs I have show 13 pins top row, and 12 pins bottom row and pin 1 is top right, pin 14 is bottom right - if that is any help.

I cant do that myself, unfortunately, all my inputs are electronic and relying on the table moving too and fro.
Not me driving the engine - I'm better looking.
