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.
You will notice that 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 design will only work in combination with the Digital Bird Motion control system. It has not been designed to work with any other system or software.
As before you can purchase a kit of non plastic parts here: Focus Motor Kit
The kit is supplied with all the non plastic parts you will require to build the device including motor, gears, driver board , connection cable, screws and fittings. The motor is provided with the new kits with the gears fitted.
Build Steps
Notes for Upgraders
If you are upgrading from an earlier version using your original control board you will need the following:
You will need to bore two new 3mm holes through your control board for the revised back screw positions and remove approximately 4mm from your motor shaft length. You will not be able to use your old motor with this design since the previous design removed the motor mounting tabs which we are now using! Sorry Remember also to remove the encoder magnet from the back of your old motor and position it on the new one.
