NEMA34 upgrade - eviltoast

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.

    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.
