Re: Yeager CNC Pro and relay settings

---
Hi Alan,

I will have to check the swing and cable when I get to work.

The 5 Volt to the + term on the SSR is from the games port
(pin1...this does work) and the ground term on the SSR is connected
to the pin 1 into the PP port. Is this wired wrong?

The machine runs and appears to do all its movements execept for the
SSR part not working.

Thanks


Shelby
