What are the two digital readouts all about?
I've always wanted a set of Greenlee punches. I had no idea that you could get DB9 punches. I imagine they also have db25, RJ45, etc.

The two readouts:
Both devices are < $10 Aliexpress commodity type items. One is a thermostat for the little fan that actually never turns on because the temperature in the case never seems to go over about 35deg C
well at least I planned ahead. The other is an over-voltage relay set a shade over 220V. The drives I'm using are rated for 220V. The manufacturer spells out the absolute upper limit pretty clearly IIRC 242V. So I dug through my transformer box and found a 240:24V and instead connected it as a buck transformer to give 220V@20A. If nothing else that over voltage relay gives me a warm and fuzzy feeling displaying its "221V" so I know the drives are powered and how much total current they are pulling, which is usually not very much.

Very nice thinking! Not sure what you mean by generic. Got links?
You had better be sitting down if you ever price out a Greenlee DB-9 punch. You are probably looking at about a thousand bucks. I recently missed out on getting one for free.
Looks like you might be missing a servo drive.
I see @slow-poke has four in his box. Now is the time.
The DMM servos I have come supplied with power and encoder cables. I don't know if they are shielded or not. I will be using shielded cable from the controller to the drives though.
Yup, I've already started saving for another DMM drive and servo.Looks like you might be missing a servo drive.
Does the box spin when you turn it on?
Yes & no.
When I leave the mill for an extended time I hit ESTOP and everything is powered off.
If I'm worried about position I will re-home.
I think I demonstrated that only if the knee motor stopped under load from the ACME screw I see current draw of over 1A and the motor might feel slightly warm to touch but in most cases static current draw is 0.1A which includes the 1800W spindle servo.
Now if I'm torquing on the draw bar and start load the spindle I see current climb but otherwise they all stay cool or cold.
Unlike CNC ROUTER where Z axis stepper gets too hot to touch.

Thanks John, I’m still working out my design but wanted to check on how you did yours.
Merry Christmas by the way
