Ah. I think you mean the blue plugs? I haven't actually swapped those out between drives, but I have mounted each of the drives where the Z is on the far right and they all function well in that position. All three motors work great and as they should when plugged into anu drive in the Z location as well. This is telling me that it has got to be noise of some kind.
I have been focusing on the rear of the cabinet. I have 62 volts coming into the front of the cabinet and all of that up to the fuses are raw. That is to say unshielded. These terminals are also right in front of one of the two drives, so perhaps thats where it lays.
One thing I have noticed is on the Diag. page, when I first click on it just after I have started Mach, my input pins all light up. They slowly go out , but not all of them. This is with no inputs even connected. I did have an estop setup, but I disconnected that while I'm sorting this out.
I am wondering if this might be the charge pump? Also, I can't actually disable the Estop switch in the config. I just removed the pin and port numbers, but the green check mark stays on. I find that odd. Possible bug?
I tried to capture the diag page, but things go a little crazy when I try that.
Enhanced pulsing is enabled. I think I have tried both ways.
This is version R2.0.065
