Summary

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.

Supplies

Supplies
As before you can purchase a kit of non plastic parts here: https://digital-bird-motion-control.myshopify.com/collections/frontpage/products/digital-bird-focus-motor-mark-iii

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 gears already fitted and ready to drop into place.

Notes for Upgraders only

If you are upgrading from an earlier version using your original control board you will need the following:

1x M3x12mm slotted shoulder bolt with 6mm diameter shoulder
2x M3 washers
1x M6 washer
2x M3 Nut
1x M3x20mm cap head bolt
2x M2.5 x 20mm cap head bolts
1x Brass/copper 10T 0.8mod gear 5mm bore
1x 6x12x4 bearing
1x Round Nema 14 Bipolar 0.9deg 8Ncm(11.33oz.in) 0.65A ��36x19.6mm 4 Wires

You will need to bore two new 2.5mm holes through your control board for the revised back screw positions and remove approximately 5mm 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 to support the large gear. Remember also to remove the encoder magnet from the back of your old motor and position it on the new one.
