Motorized rotary table

[tonyfoale]

I have posted the code on HMT (above)
Please note I am sure there is a better way to programme but this is my first attempt. If improvements can be made to both codes I would be interested as this is been a long and sometimes frustrating, step learning curve for me and it has taken well over six months to get it to finally work. Lots of help and research on the net to try and understand C+ code. This was suppose to be a simple index project but grow and grow as I realised what could be achieved with the Arduino. I am more than happy for members on HMT to rip the code apart and tell me how I could improve or made it better. I feel the programming is as messy as the wiring in the control box but it does work.

I made a similar project earlier this year but I had forgotten about your project when I did it. Considering that, it is surprising how similar the final results are.

It has different modes selected by the letter keys, viz:
* Divide a revolution into N parts and advance one for each button press. (Shown in video)
* Continuous rotation at a specified speed until stopped (also in video)
* Advance to a specified number of degrees.

Anyway the purpose of this post is to enquire whether you are still interested in looking at different coding possibilities. I am quite willing to share my code if you wish. It is only 250 lines and uses a single Arduino Nano. In the meantime here are some pix. Click on them for full size.



The controller. This contains a simple transformer/diode bridge and capacitor power supply for the motor as well as a small power supply for the Nano and display.



This shows the cardboard templates for a pneumatic brake. Which locks the table when stopped. The software controls this automatically.

I use a closed loop stepper and controller. This ensures no lost steps and the controller takes care of everything.
