    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?

Achieving that with a small motor may prove to be a bit of a challenge, but you should benefit from the fact a coolant pump should have a reasonably steady load.
    My main concern would be that the coolant pump motor is running near it's rated capacity, and when running from a static phase converter you risk burning out the motor if you try running it at high loads.
    I totally agree with the above comments and would add that I check the voltages on each leg and try to get equal voltages under normal load conditions. The run cap value will be determined by balancing the "leg" voltages, and the start cap value (which is usually only switched in for 0.5-1.0 seconds) will assist the motor to start to turn. G.

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

    He's good to Go i2i the IP-A 0-10v is isolated. As are all the I/O on the Cslabs controllers.!

    stunning, they look pretty good, i wish they were about when i had my three phase triac. Saying that i still have the servo's and drives here somewhere, could be good for one of my quatros.

    On the topic of isolation, when providing 24V for the purpose of something like a limit switch, should this come from the same 24V that powers the CS Labs unit or one of the outputs of the device itself to try provide some level of isolation?

    i2i, I checked the measurements of the missing actuator last night in terms of the 2 threaded elements. The smaller end is M8 but I suspect fine thread. I tried to screw in a standard M8 bolt which it accepted but then stopped.

    The hole size for mounting is just over 21mm, I think on the phone yesterday you thought this might be 27mm ish?

    i don't remember the m8 thread being fine, and the mounting thread could be 22mm. It's been quite a while since i did one, check the one you have on there.
