Bought a cnc machine, need a lot of help

[Paul53]

Well, I have jumped in at the deep end, I picked up a home built machine this morning, the spindle is a Water cooled 1.5KW er11 and matching inverta vfd, I need to get a stepper motor kit, the guy used stepper 23, I will also need to rig up a pc, I have a few questions, does the port have to be parallel or can use usb? which is best? I am assuming I can mount the drivers etc inside an old pc and use the pc's power to run everything? I have no experience at all when it comes to building a cnc, so I am going to need all the help I can get, I know it is going to take a bit of time, but I am willing to learn. So any advice would be very much appreciated. Thank you. Paul
