Direct Drive CableCam

This is the version for the ODrive Robotics motor controller and the D5065 dual shaft motor with encoder.

The CAD program primarily used is Rhino 3D V5.0 (cablecam.3dm) but for better portability the exact same content is exported as AutoCAD (cablecam.dxf) and Step file (cablecam.stp).

In case one of the files has a problem, file an Issue in this repository.

Generally speaking, the plans consists of three areas:

3D Model of the assembled CableCam using multiple layers

Here the entire CableCam can be seen. CableCam_Plan_3D.png

Drive Shaft assembly

The drive dog is a simple D22x7xd8 disk to be clamped to the motor axle and holds the inline skate wheels. Drive_Shaft.png

Main body in 2D

The main body consists of 2mm thick CFK mostly, except for the base plate where the Gimbal will be mounted on, that is 8mm thick alu and the motor assembly plate made of 4mm alu. These parts did undergo several iterations of design, e.g. initially some parts were 2.5D elements and had to be milled. To safe costs all has been redesigned to be pure 2D parts and waterjet cutting provide the best result. A clean surface with just a bit of chamfer needed afterwards - to make it perfect - and the cheapest way to manufacture all. Waterjet_2D_cutting.png
