Got the TM R383 Mod wheel all mounted and everything is working. I’m doing more driving than debugging which is a sign that I think it’s near done.

The OpenFFBoard has shift register support so with no modification to the wheel other than a coily cable I was able to get all the buttons working. I designed some adapters to mount to an ebay QR (highly recommend this one called “For Racing Simulator Simagic Moza 70mm Steering Wheel Quick Release+Wheel Base” on ebay) which is rock solid. I was all ready to machine the adapter flanges out of metal but I put the prototypes on to check the fit and they were so rigid there’s no point in taking the time to do it. It feels easily just as solid as my real car. Kindof amazing considering the threads are even printed into the PLA, no heatserts or anything.

Feel free to let me know if you want the FreeCAD models, I suspect at least the 70mm wheel side adapter would be compatible with other TM wheels too. I use the RT FreeCAD branch so they won’t work in normal FreeCAD unfortunately.

It’s running at about 14Nm right now, I don’t have a thermister on the motor coils so I’m trying to be a bit conservative however I’m pretty sure 14Nm peak is way way more than I need personally. The motor and supporting hardware should technically support about 22 but I don’t think I’ll ever push it that hard. 14Nm is scary enough.
