Hi Forum; 

I went to use my CNC Router the other day and the cobbled together controller has give up.. Won't even boot after a few kicks and wiggles...

So I've put together a Raspberry Pi LinuxCNC controller with a mesa board to squeeze into the old PC location.

I've gotten  the Pi5/LinuxCNC all running off the boot image but just yesterday received and added the Mesa 7C81 I/O board. 

It's assembled and powers on, now I just need to figure how to connect the Mesa I/O to the outputs from LinuxCNC.   I guess it's time to read.

If anyone has a good 7C81 configuration page they can refer me to I'd appriciate it.  Ive just started and am not stuck yet but love a good example to follow. 

Adventure Awaits!
