Another update:
I did make the first chips a couple of days ago, but it really doesn't count. I just took a light skin cut on a piece of stock using the MPG as part of getting the axis calibration and offsets figured out. Needed to figure where the spindle centerline was relative to the turret face and relative to the X home position and the tool setter. Figuring out exactly where everything is at on a CNC lathe is a lot more complex than a mill, I'm on a bit of a learning curve here.
I have all of the sheet metal back on so was able to test the coolant pumps. They work fine and are under computer control.
The next step is to get all of the offsets figured out in the software so it's operator friendly. When done, I'll be able to index through all of the turret positions and set all of the tool offsets from the tool setter. You can approach the tool setter from either side and is also useful for finding the exact width of a parting or grooving tool as well as locating the exact center of a drill bit.

Setting the X axis position. According to the manufacturer literature, the tool setter switches are good for +/- 1 micron. Close enough for me.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

And setting the Z axis position
