If you have ever tried to use the SRX Mag encoders with the Toughbox Micro, you might have noticed that the grommet’s height that comes with the kit is not enough to tune the encoder’s distance from the magnetic shaft.
The most common solution to this (that I have seen while researching!) was shortening the shaft in a lathe. However, for teams like us who don’t access to a lathe right away, our mechanics lead found a much simpler solution. He simply grabbed some Lego Tires that were sufficient enough in height and diameter. (I don’t remember the exact size, but I can check it if anyone is interested!) We simply swapped the original grommets with lego tires and it was perfect. To be honest, it was very sturdy and reliable.
Overall; for teams who are having a similar issue and do not have a lathe/don’t want to machine the shaft, this is a great solution as far as we have experienced.
