Project about how to connect shifters (sequential or H-shaped) on Fanatec Wheel bases, using it's internal protocol. Tested with a sequential shifter on CSL elite 1.1. Also the 3D models for the Levers and electronics are provided. In this example, we can connect directly our shifter levers to port Shifter2 (rj12) also works on Shifter1.
The problem is simple: interface the wheel base so we can send two signals, gear up, and gear down. Fanatec sells static paddles, a fully H-patter shifter, and also a sequential shifter. Some wheels include the shifters, also (as my BMW GT2 wheel). The problem
with that wheels in that the paddles moves along the wheel, so in tight turns (aka rally) you can't reach the paddles.
All the parts are designed on Autodesk Inventor 2019. I provide the STL files. Printed on a Creality Ender-3 Pro, with BQ PETG. These are the CURA settings for all the parts printed:
* Layer Height: 0.2
* Wall Thickness: 0.8
* Top/Botton Thickness: 0.8
* Top Layers: 4
* Bottom Layers: 4
* Infill: 60%, Grid
* Printing temperature: 220 ºC
* Build plate temperature: 80 ºC
* Speed: 50 mm/s
* Cooling: Enable
* Fan Speed: 100%
* Enable supports: Everywhere
* Build Plate adhesion: None
Note that all the parts are sturdy and the print time is about 3 hours for the plate. Let the printed print. Check that the nozzle in clean (run small batches) because the PETG is very sticky and stringy.
First of all, mount the lever adapter into the levers. If you print your custom paddles, skip this step. Add the spring into the back, and glue it.
Insert the lever into the base plate, and pass the M4 screw as axis. Bolt it. Sand all the parts to get a smooth operation. Then, screw the cap tight. This part is the interface with the plate, and limits the travel of the lever. Screw the levers into the plate. You're done.
Mounting on wheel base
Put the plate in the wheel base, and place the reinforcements. Screw the big M6 screws in position, and tight it. I use some double tape to avoid any hold between reinforcement-cap and plate-wheelbase parts. Mount the wheel and check that nothings collides and the wheel moves freely and smooth. Now, we can mount the electronic components.
