2020EA Spool Feed Unit (Top Hat)

No bearing, No oil, No other stuff. I use PLA. Two top bolts must be removed (two more if you have dual z lift). Do not do this while running. Slide mount onto top 2020 extruded aluminium. Right of center. Replace bolts (check for square). Screw in 2020 bolt into mount. Slide spool holder onto mount bolt. Spool holder diameter is 52mm (elegoo cardboard spool). 72mm sock or sleeve for larger type spools. I used to use printed filament guides but found them unreliable, I now use metal wire (see photo) (small loop,60mm,3/4triangle,90mm,small loop). This system has worked flawless for some time now. Have Fun Creating.
