Upgraded from a NEMA24 to a NEMA34.
Before going out and milling or buying it in metal it is always a good idea to testprint it.
Probably will use the plastic part for a while as 3mm wall-thickness PETG seems might already be good enough.

I see. Size doesn't matter to you. It is all about skills.
Let's me introduce you to the 400W NEMA24 servo.
edit: Sorry. Was only the 400W unit. Somewhere there should be a 750W speciment.
Also be careful with these motor. While a small NEMA17 found on 3D-printer has 0.5 Nm and under normal conditions will stall before serious harm happens this NEMA34 is 9Nm which is enough to break bones. Those 400W servos are equally dangerous. While only around 1Nm they have roughly 4Nm peak and keep this torque at high RPMs.
I'm sorry, I'm just insecure because I'm a small boi myself with a 8D shaft
Not bad either.
Previously I had a 1.85Nm on this axis which wasn't enough to reliably pull 1'500 mm^2/s acceleration milling metal. All sort of issues from overheating stepper driver to it losing steps.
Yeah I used these in my manual mill converted to do power drive and some basic CNC stuff. They are excellent and have a lot of torque, but they are also very slow. Especially with the amount of step down gearing in a manual mill, the end result isn't very fast. But I don't really care, I'm usually not in a rush to do anything.
