Hi! Did you ended up using hte 4th axis harmonic drive? I just got one and wired up. It looks ok but i notice the chuck has this huge play. Do you also have it? I thought it should be gapless with not backlash. I am confused. :-)

Here the video showing it.

Ah ok. Well if you will have justa minute maybe try to replicate what I have shown in the video. In my drive the front can move without turning the stepper motor. I thought harmonic should be backlash free or gapless as the seller mentioned in the product title. Thanks! :-)
