Simple camera gimbal for timelapse and stop motion photography, or motion control.
Let's you accurately position your camera in two axis or move through a pre-programmed sequence. Home switches make position control repeatable even after loss of power.
Supported cameras (as reported by makers):
Nikon D3400, D850; Canon 70D, 5DmkIV
Most parts should print without supports (except cableJunction and motorMountA). Some larger parts can benefit from a small brim though, depending on your print setup.
I printed most structural parts with a wall thickness of 2mm and 1mm top/bottom to get the desired rigidity. This can be tweaked depending on your requirements and application.
Use a good epoxy to join the parts that are printed in multiple parts. (Tip: leave one or both arms unglued for easier assembly)
The small pinion gears (SpurGearM1x16) work but not for very long, at least not with PLA, forces on these are quite strong. They will get you going but metal versions of them can be had for extremely cheap from China/Ebay (search for M1T16 pinion gears).
I switched mine out after a while and it's working very well every since.
You'll also need:
4x 6000 Series deep groove ball bearings (OD 26mm ID 10mm Depth 8mm)
2x Nema17 stepper motors (mine are 17HS8401, 1.8A)
1x 10mm aluminium tube or similar metal shaft
2x proximity sensors M12 (optional, mine are LJ12A3-4-Z/BX)
The cable junction is proportioned to accept 3 mini XLR type sockets.
Let me know if I forgot to mention anything else.
Oh, it's designed to fit my D3400 with cables sticking out. I don't have a full frame camera so am not sure what other models will fit on it. Let me know if your camera fits and what model it is.
Enjoy! And let me know if you do anything cool with it.
I am controlling my gimbal with g-code, Grbl 0,9, a Raspberry Pi and a set of cheap noname stepper drivers. Quite a minimal setup.
