Perfect, thanks.

Getting pricing from http://www.jjairsystems.co.uk/ for the manifold, 5 solenoids (2 x ATC left / right), 2 x ATC down / up and drawbar).

you wont need 5, just three. The in/out can be done with one valve, same as the up/down.

Ah ok thanks, does it have 2 electrical connectors per solenoid then or does it pulse both?

when the valve for the horizontal ram is off the carriage is held out under pressure, when it is on the airflow is reversed so the ram pushes the carriage in. Same for the up/down.

We have life on all three axis.

Nothing quick or exciting but executing some g code, slowly.

Next to do the spindle and home switches.

Thanks to all that have helped thus far.

Some bastard, 20 years ago, thought he would be funny by reversing the Z axis encoder ..... explains the odd behaviour that wasn't consistent. Why would it be different to X and Y?

remember the need for isolation on the 0-10, there cannot be a connection to ground it must be dc isolated.
