We had serious issues with the COTS shifter hardware this year in the 3 CIM Ball-shifter
- The plastic coupling broke, slipped or let the c-clip fall out on several occasions (we were stuck in low for an entire event because of this). We solved it by 3D printing a custom coupling anyway that worked much better for us.
- The hardware is very tough to replace or service if anything goes wrong because of how it is mounted in the COTS solution.
- This design incorporates a female threaded piston, so just stick a bolt and washer in there and we don’t have to worry about the orientation of that little nut in the COTS hardware
If I am going to replace a lot of the kit anyway, why not just grab the piston from McMaster as well and use something that’s easier to incorporate into the design?
For the encoder mount, we really like the SRX Mag encoders, which don’t mount in the existing encoder plates. In any case, the original mounting hardware would be hard to integrate into the design anyway.
Thanks! I’ll probably fix that in the next revision. I completely overlooked that
This will probably make a lot more sense when I post the Swerve design, but the it basically mounts flat onto some C-channel that has clearance holes for the CIM and shifter hardware.
Thanks! It’s a 3D printed coupling.
One of our mentors works for Brecoflex so that is what is accessible for us. We also love the fact that they offer literally unlimited options in terms of belts and pulleys. The AT5 tooth profile coupled with polyurethane/steel belts seems to be working very well for us since we can get away with thinner belts.
