Seems like you have the angle setting number on top making it easier to set the angle of the tool. If possible a couple of close up picks of each would be nice. Thanks.

:bow: amazing work! |

Forgive my ignorance but why is the harmonic drive neccessary? Is it just a simple case of the steps are too large without it? |
| CallMeAl:
Very impressive work! :clap: I would be even more impressed if I know what it was. :scratch: |

Woah, what a neat project. I had never heard of a harmonic drive until this post but after looking it up on wikepedia I'm impressed by such a simple device that does such a good job. 100:1 gearing and no backlash means you can get fantastic control and holding torque from a tiny stepper/servo. Very impressed! |
