Looking nice! 0.0018 degrees/step, assuming you use a 200 steps/rev. stepper motor, yields a 1:1000 reduction, which, in my experience, equals multi-stage gearing, resulting in high backlash. Have you measured your system's backlash yet?

Hi, the the prototype in the video yes it is multi-stage, worm gear drives a twin gear which drives the large white gear that can be seen in the video.
The gears were raided from projects and hacked together so the linearity and backlash are pretty bad but served the proofing.
Now I've build a 3D printer I am in the process of printing a custom gear-set to improve the meshing and reduce backlash as much as possible. I'm also updating the electronics to use the Pololou stepper drivers as used by the 3d-printers to improve the stepper control and microstepping, this should help reduce needed gearing and provide smoother control.
I have way too many projects on the go but I'll get there :)
Cheers

Salut! Am dat de tine pe rhcforum, unde ziceai ca faci piese pe comanda. Mai e valabil? Daca da, poti obtine piese cu tolerante de ordinul micronilor? Lasa-mi un semn, te rog.

It's been a while, and I'm back! I haven't been idling all this while, so here's my version of a strain-wave gear-type reducer (like in this case, "a kind of" harmonic drive): DIY Strain Wave Gears, 1:50 ratio - prototype 2
