John ,

Thank you very much for all your help .

I will order the c10 break outboard and wire as stated in the ports/pin lay out in mach3.
Then i assume i will need the adapter you have linked on ebay to connect to the pc printer port cable. so will order those .

the limit switches that are in place on the machine have never worked since ive had it so will get those up and running all at the same time using the attachments you have provided.

Thanks again
