Digital Bird Focus Motor- Mark III

This is mark3 of the DIgital bird focus motor designed to work with any of the Digital Bird 3D printable pan tilt heads.

This new design is slimer, simpler to build and has more torque than the previous models largely down to its new 1 to 4.4 gear set. If you have built one of the previous models you can re-use the main control board but you will need to purchase a new motor since this model uses the motor support tabs we removed on earlier versions! Sorry

Functionally it works just the same as previous versions but is more capable of moving those stubborn heavy zoom rings on larger photography lenses and has as slim a profile as the motor will allow.

As before there are Left and right hand versions of the parts so you can build the versions which suit your particular camera setup. My Sony A7iii setup for example requires one on each side of the lense for focus and zoom so I use one LH one RH.

Note: There should be no problem using this new design along side earlier versions you may have already built.

This focus motor has been design to work with the Digital Bird 3D printable Motion control system. It has not been designed to work with any other system or software. However since the design utilises a TMS2209 stepper driver and AS5600 encoder it could be readily adaptable to your own software applications.
