An oversized VFD is never a problem, you can always reduce the max current.
But if it is undersized for the motor (and some older motors take a huge current at zero speed) there is no way round it.

If they really are the same price and size, then it's an easy decision.

Pattern-making is boring. I just 3D printed it.

Nice.

I put it off long enough. Time for workshop tetris.


Enjoy.
