A rigid, ultra-light and easy to use motion control solution for time-lapse photographers looking to lighten their load for backcountry shooting endea...vors.

The best way to control this unit is through the eMotimo TB3. In my case, I gutted my TB3 and made an enclosure for the electronics. You might be bett...er off using the TB3 in it's stock configuration to turn this into a 3-axis system. The TB3 is by far the best motion control solution for affordable time-lapse. The firmware and user interface is intuitive and incredibly powerful. It offers power saving features that are optimized for use with my custom worm drive. You can multiply the amount of usage from a single battery by about 10x with the worm drive and eMotimo power save mode. While doing so, you will still be able to do full vertical moves with the motor powering down between shots. This is impossible with any of the planetary geared motors available. The worm drive solves this problem and opens up some additional flexibility like the quick disconnect "sliding" worm mount. This allows you to disconnect the worm drive (without removing it) in a matter of seconds. Once disconnected, you can freely move the cart to reposition or shoot video moves. The base motor mount is also compatible with the planetary geared steppers.
Easy belt tensioning with a sliding belt block.
The mini-legs inspired by Dynamic Perception for low shooting angles. If ultra-light is not a requirement for your shooting needs, I highly recommend investing in the aluminum legs from Dynamic Perception. I own a set and absolutely love using them when I'm not in the backcountry.
