To continue this spindle saga.
What I have done in the last 30 hours. Removed mach3 and all associated programs, Plugins, Brains. Did a clean up and compression of my drive. Loaded Mach3 R 3.043.066 version up, ESS plug in v 10hd2, MPG Brain. Reconfigured Mach. The saved xml didn't load my previous settings up, so I started from scratch. For the spindle, tried step/dir instead of PWM both on the ports/pins spindle set up page and the ESS's page. By the way, I wired the VFD and The C41 the way Arturo insisted I should connect them. The spindle excepts speed commands, and stops on M5, the Relay doesn't click. However, when I exit from Mach it starts up and keeps cycling, the Relay is clicking on/off. When I open Mach the spindle stops. I went back to setting the everything back to PWM, but the same exact thing happens. I'm attaching my wiring diagram, in the hope, that someone takes a careful look at it and tell me if it is wrong. I had Arturo and Hood look at it and they both say it should work. Go figure. I did find a guy on the forum that had similar problems, but I can't find him any more. The most frustrating thing in all this is, that I can't find anybody to send me back my own drawing with the wiring corrected. Is that such a big deal, I ask? Here is hoping someone’ll get me out of this hole. Please, no fancy technical words, just a simple diagram, or explanation.
