Thank you for your reply. The CPM 3020 uses stepper motors so will the current drivers run with mach3? I guess I`ll just have to identify the step and direction inputs and connect accordingly from the BOB. I realise that I actually need to wait for the machine to arrive and then I can take pictures and post them up here.

I would like to use KAY but it expensive. I have a little knowledge of cnc from when I used Mach3 on a TEP but I`m not clear what original software would run the machine.

It would be good to run the machine off the original software to see if it works and then upgrade it to run off mach3 but seems silly wasting money.
