Seems that placing an assembling machine close to a beacon filled with Speed 3, reduces the quality percentage. Enough modules and the quality drops to 0% and it never makes anything better than normal.
Removing the beacon restores the +quality percentage.

If you want to get ahold of me I'm almost always on Discord.
