Hello,
I've posted in the past about my sherline 4-axis set up, but I'm having some new difficulties at the moment.
Just to recap:
I have a PMDX-126 plugged in to LPT1 on this computer. It is controlling things like INPUTS to active OEMs, as well as starting/stopping a laser that is wired to it.
On LPT2 I have my sherline 4-axis control board hooked up. There is where I run into issues.
I can't get any response from the motors when they are plugged into to LPT2. I've attached the first tab of the ports and pins config page, as well as the setup for my motors page. I'm not sure if the dir port has to be the same as the step port. Even if it does, I still get no response when both step port and dir port are set at port 2.
I would just run the motors on LPT1, but mach3 won't let me change the PMDX's location to LPT2. Everytime I try, I get a "need external estop" issue.
I would be very grateful for any suggestions on how to proceed.
