Drum constantly making a grinding sound

R2 & R2 Pro Specific
1

I performed a deep clean, and after reassembling it, the drum produces a grinding sound in all phases. It gets louder on the roast cycle

Check page 27 of the official manual:

And I would also check if the screw that holds the handle of ejection door isn’t sticking out and hitting the agitator blades.

I had the same issue. This what I did… When I took the face plate off I was not aware of the shims behind the bearing, in fact there were 2 of them. I found the shims, replaced them on the shaft and the roaster has been happy… Hope this helps.

Thanks everyone. I changed the shims and it’s fixed now
