Recommendations for next M4 production run

Maybe try reducing the feed rate and/or increasing the RPMs (not a huge range on RPM adjustment though) would help with reducing the chatter you’re seeing.

Are you on a vertical frame or have it horizontal? I could definitely be
wrong, but I think a certain amount of friction is intended in order to keep
good cutter contact and sufficient pressure.

No, friction between the sled and the workpiece is all harmful (impossible to
eliminate, but harmful)

the weight of the sled and the tension on the belts produce force to keep the
sled in contact with the workpiece.

Friction causes the sled to not want to move and instead want to tip as the
belts pull on it.
