This is a full description of everything you need to do to get SLIDER up and running.
|Box top||n/a||3D printer required. ABS was used in the prototype, PLA is probably fine.||STL file|

|M3x20 machine screws (x8)||For closing box. Any length ≥ 12mm is fine||Easy to find|
Electrically connect the components using the following schematic. Every connection is a single Female-Female jumper wire, except the connections to the rotary encoder, for which you will need to strip one end of each jumper wire and solder it to the rotary encoder pin.
It’s fairly obvious where everything attaches to. Note which screw is for what from the parts list above. Here’s some images of what you should end up with. You may find it useful to wrap the encoder in a little electrical tape as shown to reduce friction with the top of the box. Be careful setting the wires, try to minimise friction between the encoder wires and everything else. You may also find it useful to add a little adhesive putty (Blu-Tack) on the connection from the motorised slider to the bracket.
arduino-cli, then run the following commands
from a *nix box:
git clone https://git.sr.ht/~tim-clifford/SLIDER-firmware # get the firmware cd SLIDER-firmware make setup # install the dependencies make build # compile the SLIDER firmware make flash # flash the firmware onto an attached SLIDER device.
