Note

Note that all links below are examples to indicate the type of component. Please search locally for a source of supply. It can be noted however that AliExpress, Ebay and similar options is sometimes many times cheaper for some of these components so make your investigations carefully. For the PCB manufacturing there is also Germany based Aisler which I used.

Notes

  • Note 1. The 775 motor axle length of the 775 motor in the link is 5 mm to long to fit the planetary gear used. You may look into other options to make this motor + planetary gear match. I just used a dremel cutting disc to cut off exactly 5mm, problem solved.
  • Note 2. For the roll axis motor flathead M4 is used. Socketed screws are too high and hit the motor.
  • Note 3. The supplied 5V fan on the heat sink cannot be used. Another 24V fan that also can handle PWM (with only two pins) is in the part list.
  • Note 4. A heat sink is recommended on both motors. The pitch axis normally has the most forces though and will require a fan, but depending of your settings the roll axis may also need one. Test and measure temps.
  • Note 5. A wood board (bookshelf, mdf, plywood). A simple 18 mm shelf made in mdf and cut to exactly 275x400 mm is a very good and cheap option. I used a pine shelf, which works but is not optimal, the fibers will pull the drill a bit making it harder to make precise holes and it is more lilkly to twist.
    A STEP file for the board is provided that makes it easy to CNC route this board as an advanced option.

Connectors

Connectors for the PCBs can be either screw terminals as in table above, plain 2.54 mm pitch pin headers AliExpress, or some other connector type like JST XH 2.54 Connectors. Note that the linked example of the JST connectors has no 6 pin variant, also the length of the wires are 140mm, which is to short for some of the wiring. See Wiring section for more information and options.
