I'll apologize ahead of time for the long post.
I bought a Phoenix CNC wood lathe for $200.00 in a GovDeals auction last Summer. Since then, I have done the following to get it running.
I bought an old Compaq PC for $75.00 and installed Linux operating system and EMC2 software. Linux and EMC2 are downloadable free from the Internet. EMC2 runs g-code programs.
I had to replace the power supply and stepper motor drivers. I bought two stepper motor driver boards and a breakout board from a company called Probotix. Cost was a little over $100.00 with cables and a new fan. I already had a suitable power supply.
I bought a parallel port (printer port) card for the PC because the one in the PC did not have a minimum 5-volt output required for the stepper motor drivers. Cost of the card was about $25.00.
The EMC2 software allows you to define the outputs for each pin on the parallel port card. I can post those or send them to you in an email if you need them. You use a standard printer cable to connect from the parallel card to the breakout board, and then two small cables to connect to the stepper motor driver boards.
I bought a replacement carbide cutter from Forest Scientific for $100.00. There is a man there named John who used to work for Phoenix. He knows a lot about the machines, and he has a lot of spare parts.
I hope this helps.
