^^You’re missing the point. I was sent M3 screws by Marmot, and he’s sent those exact same screws to everyone who has ever ordered side cheeks from him. No issues with all existing machines.

When I tried to use them, I noticed immediately that they were sized incorrectly. I went to the hardware store and bought a fresh set of M3 screws with Phillips head. Still had issues.

He told me that I am not the only one to experience this issue. There are several threads on this forum about this.

So it has nothing to do with using the “right equipment.” It has everything to do with the “right equipment” not being “right.”
