Some of those large, high-end Japanese names have temperature sensors installed
throughout the frame, which they use to compensate for thermal expansion.
Curious if anyone has ever done that with LinuxCNC?
Steel thermal expansion coefficient is around 6 parts per million per degree

For that price, rip out the guts and replace the works with COTS units. You
end up with single phase. Possibly only a 3HP spindle but do you need a bigger
one? The Chinese AC Servos appear to be pretty good. Even the squeal problem

Looks pretty good to me. As Jon said fanuc servos are a pain. But so is

The actual error message when LinuxCNC fails to start would help.
But, perhaps you have a separate spindle.hal file that conflicts with

Unless I add stuff to the HAL file apparently there is no accel/deccel values

It might be worth adding a slower de-acceleration value for the spindle as a
heavier tool may trip the servo.

But my converted car port ceiling is probably too low.
Looks really nice. If the spindle is good then it's a good price.
