3D Scan Forum

Has anyone updated there arduino based turntables to use time in position verses the coms? Looking to implement something different on my turntable but I'm not much of a code guy. Seems like with the way David 5 works you need to have a time/position based system to get the automatic turn table to work.

Sunce the COM port is no longer available in Version 5, a work around is to automate the process with an external Macro controller like "AutoIt".

Far from perfect but better then nothing

I haven't tried it but doesn't the automatic function look for movement stop and then start the scan again. If that's the case you would just need to understand the timing of the scan elapsed time and then set the turntable to move X time.

In theory. In practice however, it doesn't work as well as it should. David sees no movement where in fact there may be small residual movement or resonance in the object or fixture. The result is lousy surface quality.

Hello everybody!
Can anyone share arduino scatch for turntable (which is made by arduino uno + easydriver 4.4 + nema 17 motor) ?

Look in the old forum, There are a few very good threads (with code) there.

Thank you.
I wonder if diy turntable will work with autorotation function in david 4 ? Or this function is able only for original David's turntable?
