If you wanted a more durable part, you can send the STL file out to a
service that prints it in stainless steel. You might change the design to
reduce the bulk because they charge by the gram for the steel.

Thanks Ken and Gene,
The X and Z cables were miswired. I was pretty sure the problem was not in
the controller box because it was working with the X2 mill.
Now I can work on the homing sequence.

"Shuttering" is a frequent symptom of a mis-wired motor. Are all three
motors wired identically? Check the cables!

There are some other printable filaments that are far more flexible. More like

When I first saw this, my idea was to print the internal tooth gear
"backward" as a mold that makes up the central space in the aluminum
housing, then pour in an epoxy/glass composite paste.

I would be interested in hearing back how the TCM drivers do with those motors.

So - this didn't make it 6 hours with the steppers running 833rpm
(3000deg/min at the face plate) (forward reverse some positioning...)

Velocity control + PID = position control.
Here is a schematic of a typical LinuxCNC spindle orient setup:
Thanks for the replies.
I adjusted the current, initially by measuring the reference voltage to get
(from memory) 150mA. That ended up warming the motor too much, so I reduced
it some more. Regardless of the current, the behaviour didn't change.
I do have some TMC stepper drivers around, I
