Chinese 'Hybrid Closed Loop' steppers vs 'regular' open loop steppers

[clutchslip]

I’ve been using a Norma 34 close loop stepper on the Z axis on my boxford bud cnc conversion lathe. It’s been up and running 2 years and works perfectly. Very accurate and I have never noticed it loosing any steps
The nema34 is direct drive through a 5mm pitch lead screw
Would it have performed the same without the close loop, I’ve no idea

Thanks for the reply Paul, good to know yours have been reliable. My setup is not a direct drive like you have on your Boxford, but can I ask what motor torque capacity you went for your Z axis? What vintage is your BUD by the way?
