I got another (hopefully easy) question.
I'm using a PMDX-126 so I can have external cycle start, feed hold, and rewind functions. Those are working fine, the OEMs thread was very clear on how to accomplish this.
Now I am trying to control both the PMDX and the sherline board with the computer. I have two parallel ports on this PC, so I thought this would be simple. I plugged the PMDX into port 2 and the sherline board into port 1. This was because I had originally set up my motors on port 1. I moved all of the OEM triggers to port 2, but Mach keeps asking for an external E-stop. I tried setting the port for the E-stop to port 2, since the PMDX has a dedicated spot for E-stops, but after pressing apply, and exiting out of the ports and pins tab, the program returns this, "Your reset command is failing due to an external influence...etc"
When i return to ports and pins the E-stop was reset to be at port 1. Is this just where the program wants the E-stop to be connected? That is fine, but in that case, how do I reconfigure my motor outputs so that mach knows to communicate with port 2?
