Hello Chuck, I was really interested to see this, as I had been thinking of something along those lines. Couple of questions: 1. Is the rest torque of the stepper enough to withstand milling forces, or do you think some kind of spindle lock or brake is needed once the rotation position is achieved? 2. In the youtube video where you machine the pentagonal cut or the gears, what did you use for the main collet/spindle that is in your vise? Scratch built or ?? 3. Have you decided to share the arduino source? I would love to play with it. (I am an old C programmer and have programmed the arduino, so I won't bother you with any follow up questions about it!) 4. I am looking at this in order to make some larger XL timing belt gears in order to make a belt drive for a split ring telescope mount - imagine my surprise when I saw all your telescope work on your website! Did you make the gears for this, or buy them? (kind of a chicken or egg problem!) 5. Would you still stay with the polulo stepper driver, or do something else with microstepping, like EasyDriver (sparkfun), or go with something heavier in terms of power for more holding force? Anyway, thanks for your work on this, and I would like to encourage you to update your very informative website!! I know what I am asking here, as I maintain some of those myself. |
