I started on my Techno Lathe in 2019, I got it running with the Lenze VFD, but changed to a new VFD that had better features and ease of use.

I purchased a GS2 series AC micro drive, enclosed, 120 VAC, 1hp with 1-phase input (this may have been replaced by a newer version) for about $200.

I also installed a braking resistor (which I removed because I felt I didn't need it plus the screw on chuck).

I haven't done much with the lathe, but just starting to play with it and the mill.

I would recommend going with a newer VFD that may give less electrical noise and more functionality and better documentation.

I'm hesitant to put more money into it if I haven't even gotten it to spin yet
What motors and drivers did you go with?
Did you get the factory encoder to work?

Tecnik ClearPath's servos.
My Lathe didn't have an encoder on it, I was able to add a pully to the spindle and belt 1:1 to an encoder.
