Do I need to apply a ground on tb4-1, and some of the local 12volts to tb4-3 just to demo that its working? It makes sense but I'd druther be safe by asking.
I can see the other pwmgen.1 on its p2 pin, so routing that to the pwm-servoamp in the G0704 will not be a problem. But the 6040 has a vfd and will use the spinout 0-10 volt analogue signal. What I'm trying to do is set this up so essentially the same bit of hal stuff works for both machines and only the signal wiring in the control box is different. One potential problem might be needing a delay between the enables and the boot module for the pwm-servo amp in case the opto's in the isolation are slow, but thats a bridge I'll have to cross when I get to it. I built the original boot module to bang it a bit harder, and 5 times in each direction, so its probably enough. Thanks Peter.
