Hi! I've got EMC2 and Ubuntu loaded on a 1GHz PC with 256Mb RAM. The parallel port is wired up to a 4-axis driver from Nudrive. For some reason, I can jog the first axis and the third axis correctly but when I try to jog the second axis, no matter which direction I use (+ or -) the axis moves in the same direction. Any ideas on how this can happen? Is it some sort of weird wiring mistake or is it more likely an incorrect setup with EMC2? I've set the parallel port pinouts for the second axis to dir 9 and step 8 since my second driver is not working for some other reason. I'm kinda stumped. Thanks!
