FAQs / Can't get any response from parallel port

« on: February 12, 2009, 03:42:29 PM »

I can't seem to get Mach3 to interact with the parallel port on my computer. I checked in the device manager, and I have the address correct (378).  I couldn't seem to get my motors to respond, so I tried setting up an input switch as shown here http://solsylva.com/cnc/xylotex.shtml . However, triggering the switch shows no activity on the diagnostics, and using the auto-detect for setting up an input switch doesn't detect the switch when pressed. I just switched over from EMC, and the setup worked previously, so I'm not sure what the problem might be. Any ideas what I can do to troubleshoot this?
