UPDATE 2018-May-28: Uploaded firmware source+hex, thing file "StarScan_FW.zip". Compiled using IAR but can be easily adopted as the source is really straight. Not the best stepper driver management but was OK for my purposes.
UPDATE: Uploaded StarScan Brain (controller module). Not so much information on how to make but you can check the StarScan in action, videos attached.
To be honest, StarScan Dub is not the Scanner but the Turntable designed to get all that bunch of photos. The reason to build that device seemed to be rather clear - as I am designing a lot of devices combining the pre-built modules, a lot of time is used to create the 3D models for all that modules. And I hoped that the StarScan project will let me to get all these models automatically using modern photogrammetry software. Now I do understand how wonderfull were my hopes and that there are no software that could be used for that purposes. After all, I did it - the StarScan is alive and can be used for any tunrntable purposes.
The StarScan Dub s based on Nema17 42mm stepping motor (200 steps per round) as I have already owned them. The pinion gear is the widely available 16-teeth aluminium GT2 gear used in 3D Printers and the main gear is 3D Printed 90-teeth GT2. The belt used is 200mm (100-teeth) GT2. Additionally you need 1x 608ZZ ball bearing, M8 bolt, M8 nut & M3 screws-nuts (nyloc nuts). The table surface is the D180 round glass for the Kossel 3D Printer (I have ordered D220 size glass but at first received smaller one, later the correct-sized was received and I did not know what to do with the first).
All parts were printed using PLA and 0.3mm nozzle/0.15mm layer (I do prefer longer in time but higher quality printouts), and you need 3 "GlassHolder.stl" copies. The flat holders surfaces can be used to fix glass to holder using clips (not shown on the photos).
The only additional device needed to get the complete turntable solution is the Controller that pulses Nema17 and remotely controls the Camera to make all that shots. I have designed one with a lot of settings (etc Camera Type, Shots per round, microstep size, rotation speed, all that time delays needed for thet Camera to save the photos) but not sure there is enough time to share all that. Maybe later if I have time to design Controller case :)
Any questions do not hesitate to contact me.
PS The StarScan Dub legs are FOLDABLE to minimize storage space! I do really hate all that space-consuming devices with huge fragile parts you can easily break placing the monster to the storage room. That is why you can easily remove the StarScan glass, remove that big 90teeth gear with belt, fold the glass holders and store all that anywhere.
