Ok, so I'm 99% there! I just need a computer to run Mach 3 as I run a Mac in the home office. I should have a PC by Sunday and have the lathe fired up!
Wiring is all done. I built an entire control box, replaced the Z and X stepper motors, and rewired all of the limit switches. Here are some pictures of the finished control box.
The last picture shows the locking mech on the tool changer. I watched a Youtube video and see that the tool rotates past the location it needs to be and then turns backwards to lock the tool in place. Reading the instructions for Mach 3 I just learned that they don't have a provision for a tool changer, just offsets for different tools. For now I will have to turn the turret by setting up hot keys on the key board and just jog the stepper motor manually.
Let me know if you have any questions,
Dale P.
