Parallel Port breakout boards, motherboards, and dedicated accessories / Re: Max output current

Sorry I didn't mention I was using a PMDX-126. I also didn't realize the 126 was buffering the output. So 16 mA it is. Thanks for the reply.

I was thinking since I'm using a smoothstepper the max current for the output would be determined by the smoothstepper (32 mA). Would this be
the case?

I would like to drive a LED with output 4. My LED has a max 20 mA rating. If I configure the resistor to allow close to this will the output be OK with this current.

I am using port 2 input 11 on my PMDX-126 for my auto zeroing and edge finding probe.
Is there a simple way to add a LED at the probe so I don't have to go into the diagnostics
screen mach3 and check the input for continuity before running the script.
