I built a gantry-style plasma table. X, Y1, Y2 and Z axes, Y1 and Y2 linked together. Before I read that Stepconf doesn't work well with gantry systems, I actually got it to work.
I needed to change a parallel port setting for coolant flood (torch on/off) and now the motors turn very very slowly, maybe even just bounce a little. The example config 'stepper-gantry' fails on EMC2 load. The config 'stepper-inch' loads but obviously will not help me with my particular setup. I have a PMDX-132, 4 Gecko 201 drivers, and four motors. Nothing wiring related has changed; it is obviously software-related. I compared the .hal files for my config and the stepper-inch .hal files and they seem to match up, with the exception of the coupled Y motors. My port pinout is simple: 1 - spindle on 2 - X dir 3 - X step 4 - Y1 dir 5 - Y1 step 6 - Y2 dir 7 - Y2 step 8 - Z dir 9 - Z step 10 - N/A 11 - X home 12 - Y home 13 - Z max limit inverted 14 - coolant flood 15 - N/A 16 - N/A 17 - charge pump I remember seeing Amplifier Enable somewhere but have no idea what it was for or if it was even used at all. If I use my old configuration, EMC will load fine with no problems, but when I try to operate the motors, they whine like they are moving but barely even make one or two steps. I also have had problems with the charge pump circuitry making my controller board pulse the outputs on and off, and it never did this either. I'm all ears for help. I feel like I have tried everything, but I'm sure I haven't considering my table worked flawlessly at one time, and now it doesn't. Thanks in advance for any help. -- Graham W.
