I bought a Prolight 3000 lathe a few months ago that was missing it's control box to run the stepper drives. I wanted to run Mach 3 on the lathe any way so the missing control box wasn't an issue. I paid $500 for the used lathe and it came with a second chuck and some tool holders in the tool changer. The lathe has some really nice features such as precision ground ball screws, limit switches on all axises, a 8 position tool changer, an air operated door and chuck, and the spindle is set up to accept 5C collets. It also came with a 4" 3 jaw Bison chuck to replace the air operated chuck. To build the control box I bought three Leadshine Digital DM 856 drives, a Combo breakout board from Sound Logic, a 48 volt 7.5 amp power supply to run the stepper drives, and a C-3 pulse board from CNC 4 PC to tell Mach how fast the spindle is turning. There is an encoder on the spindle motor that tells a RPM gauge on the front of the machine how fast it's turning too. I also replaced the Z and X axis motors with some more powerful ones from Kelinginc.net to make sure I didn't have any issues with missing steps when running. The original motors were 150 oz and the new ones are 282 oz. I didn't replace the tool changer motor as it works just fine. I'm happy to report that the lathe is running great, and I have the amps turned way down on the stepper drives as I have plenty of power on each axis. With a simple M code I can control the spindle speed, open and close the chuck and open and close the machine door. Accuracy has been really good and it looks like I can easily keep .0005 accuracy. Here are some pictures of the machine and the new control box thats mounted on the back of the lathe. Dale P.
