White dust on shooter

On my team’s flywheel we have been getting a layer of white dust from shooting. For the life of us we cannot figure out what it is. Has anyone else had this happen?

Could you post pictures to help diagnose the problem?

I’m not sure if it’s the same issue, but we had a bad shaft encoder before that would generate white dust when the flywheel was spinning. Do you guys have a red shaft encoder on the flywheel?

Either you are ripping up metal or destroying balls. Check your balls, if they are eaten up then the dust came from the balls.

Do you use rubber bands on your wheels? My team uses rubber bands on our flywheel and we get orange dust on our hood. Obviously dust color will depend on band color.

Thanks guys for posting suggestions it must be the shaft encoder we have. I will definitely check it out tonight.
