Larry please post pictures of you machine so we can see what you have which will allow us to help you better. Don't worry about the wiring if you take it one step at a time it's pretty easy.

Mark, I love your ATC! I agree that it's really helpful with a cnc lathe so you can program the tool locations. My changer holds 4 square tools and 4 round bits such as boring bars. Right now I have been just using one tool and haven't taken the time to program the locations of each tool. To be honest I'm a little confused on how to program them and to me it looks like I need to have the home limit switches set up so the lathe can auto home each axis when it's first turned on as it doesn't keep it's settings when powered down.

Also I have read that Mach 3 isn't set up to run a ATC and you have to write your own program. I have my tool changer set up so I can advance the tool by pressing the + key on my keyboard. I just plan to put a pause in my program when a tool change is needed and manually press the + key until the correct tool jogs into place. Some day I will try to write the program to get it working, but I'm waiting for Mach 4 to come out first as it might have a tool changer feature.

Here is a picture of the inside of my tool changer. As you can see there is a locking leaver so the turret can be locked into position by turing the motor back a little. This is why a program to turn the tool changer will take a little time to write as the tool needs to advance and then turn back to lock it into place. My tool changer also has a micro switch inside which clicks every full rotation. I'm guessing that Prolight used this as a type of home switch.
