Hi All I am started to make a DIY Timelapse Slider. I am considering the V Slot for my project and "OpenBuilds Belt and Pinion Build Example". I like to implement 3-Axis Motion. Here the Slide looks easy for me. But for the Pan and Tilt I'll be glad to have your advise. My general plan for Pan and Tilt is ... to make the NEMA17 Stepper Motor Shaft anyhow coupled with 1/4" UMC Screw. So, for Pan control, I can connect the Motor Shaft directly with the Bottom Hole of Tripod Ball-Head. And for Tilt the same idea I wanted to apply with a Quick-Release L Bracket. For Tilt I need to make a custom Aluminium Bar based L Plate where the the Motor will Mount and the Motor Shaft will connect to the regular DSLR L Bracket. Do you think this idea will be good for Pan and Tilt? Also I am looking for a good way to connect the 1/4 UMC with Motor Shaft. Is there any Flexible Coupling to do that? Thanks in advance. Regards.
