That is one nice looking indexer!Quote:

What is the Torque (NM) of stepper motor you used
Thanks
Hello LeighS! Below is a specification of the stepper motor used:
- Nema 23 200 PPR
- Holding torque: 9.8 kg.cm (0.9 N.m)
- Rated current: 1.8 A
- Recommended voltage: 24-48 V
Very nice design and build. What are the specs for the two rear gears? Did you make these or sourced the gears from a supplier like Boston Gear?
Thanks for the comment Paul Jones! I made the gears myself. The larger gear has 84 teeth and the smaller gear has 21 teeth. I used a 1.25 mm metric module.
Very nice. Could you describe your bearings and how, of if, you preload them.
Thanks for the comment Saltfever!The bearings used are 6006 2Z number. Preload equal to 37 N (3.8 kgf) carried out through the weight of the plate and the spindle (satisfactory value for a maximum rotation equal to 500 rpm).
. . . and the CPU and software to drive it? :hattip:
Arduino UNO, Universal GCode Sender, TB6600 driver, 36V power supply.
Many thanks M-4. That helps a lot and gets me pointed in the right direction. You can tell I'm interested! Never heard of the language but I'll look it up. You have created a beautiful machine but is there anything you would do differently? Any hints of what I should look out for? I know G-code put post-processing is foreign to me. All the best.
Thanks for the comment Saltfever! G code is very easy to understand, there are several tutorials on the Internet. This project could have been done with a toothed belt, it would be a change. However, I preferred gears because I think they last longer.
