a very low quality video of my new dolly driven by openmoco.

the om talks over i2c with another arduino that controls pan and tilt.
I use a modified telescope motorized head
it´s 182cm long and you can add more pieces. You can join 2, or more pieces and you must change the timing belt.
it runs over 4 teflon pieces.

Great work Inco! Love the design - when you say "runs over 4 teflon pieces" - do you mean that you used teflon strips for the linear bearings?
Keep up the good work =)

version 0.666 :)
now I change the big nema23 stepper by a nema17 and the homemade driver by a easydriver, I add some hardware to allow this little motor to move the slide.
It takes now 2525 steps/cm, therefore I think that a int is not enough for the "move now" and "steps" commands.

Very nice work indeed =) I'll expand the move now command in the next release. To make things a little easier to integrate with future releases, we'll see what we can do to the code structure, ok? Maybe if we use objects to handle certain core functions (like serial communication) it will make it easier to override basic methods that you want to hook into.

Yes! We need objects for serial communication! I will let you know my thoughts about that soon.
