Hi Neale, and thanks for taking the time to respond.

Your correct I have no experience whatsoever, I've literally just un-crated the machine after a long storage from new, and I'm trying to get to grips with connecting the thing up to my PC. I've watched lots of youtube cnc content over the last week to try and understand what's required, but I'm still not 100% clear. Below is a description of what I think I need, however if you could have a quick look and advice in anyway, I;d really appreciate it.

My Machine: Heiz 720S
My Controller: Zero 2 (25 pin parallel port)
My PC: running windows 64bit. (USB input)

Things I think I'm going to require.

1) WinPC-NC software: (To run the controller)
2) WinPC USB controller
3) Software which can read G-Code (Mach 3/4 etc)

I was advised to go with CNC-Step Software and hardware based on my CNC machine type. If theres anything else you thing I require to at least get me up-and running, could you please let me know, as the cost is adding up.

many thanks in advance.
