This is part 2 of my Arduino indexer build. Part one was shown as https://www.youtube.com/watch?v=5GSHXC6fwq4
This will enable any number of divisions to be indexed at the touch of a button.
The electronics and Arduino sketch were devised by Gary Liming and can be seen here. http://liming.org/millindex/
Products used
Plastic enclosure 158 x 90 x 60mm https://goo.gl/iD0b5k
Arduino Uno and LCD shield https://goo.gl/GAwyP6
Motor driver https://goo.gl/NhklOv
Rocker switch https://goo.gl/pSs1bo
Push button switch https://goo.gl/7qP9ny
4 pin connector https://goo.gl/nFzJFd The socket part of the connector should really be on the enclosure with the plug on the motor but this is a super little connector and as the motor is only 3.2 volts there is no danger of shock
I could supply a casting for the toothed pulley if anyone wants one.

Super !
Beau montage !
Et vive Arduino !!!

Great !
Beautiful editing!
And Vive Arduino !!!

How did you determine what size to make the Pulley?
nice job showing how to properly solder and assemble the cable connector.
Really cool project, you could totally turn it into an welding rotary table
too!
Neatly done. Regards
Now, you will have to start a new series : Programming Arduino at home…
I have an Arduino© starter kit I should try this.
Thanks
They say you can’t teach an old dog new tricks but what do they know.
Lovely videos as always. Many thanks, very interesting and motivating.
P.s 1 I can’t wait to see a video with the new tool mounted on your Raglan
miller.
P.s 2 I’m looking for a Dore Westbury MK2, in case you know anyone having
one for sale.
Your very clever.
Good video, but a lot of noise on the background
Hi. I made a similar rotary indexer for a small CNC project. I certainly
don’t have the skills you have to cast my own pulleys, so it wasn’t
elaborate. One thing I discovered the hard way (and might help you avoid
heartache down the line) is that relying on the stepper motor to travel
exactly to the same location each time with a direct-drive setup is nearly
impossible. It will always be a fractional radian off. We discovered that
this was because if you didn’t hold power on the stepper motor after it
moved..the motor would (imperceptibly) settle back in between it’s stators.
It was maddening trying to figure this out at first, but made sense once we
had a good think on it. The motor would get unbelievably hot if we held
power to it during operation so we went with a planetary gear drive and a
stepper motor. The planetary was directly driven by the stepper and allowed
us extreme precision over radial movement. Plus the gearbox would not allow
the motor to relax in between it’s stators once power was dropped from the
motor. Anyway..hope that helps you in some way if you run into this
problem! Thank you for your videos.
Nice build. Did you have to reconfigure the code for the number of teeth on
your pulleys? Where did you get the belt and drive pulley?
Cool.
Any plans to make the stop controlled?
