CubePro Open Source Kit - External Filament Feed

prusaprinters

Using these components, you can relocate the feed tubes externally and still maintain the OEM look. I simply use external filament stands for PLA and ABS but feed Nylon from a dry box. The two recommended purchases are M5 nuts and Aleene's Tack-It adhesive (for filament chip holder). Tack-It adhesive - https://www.amazon.com/Aleenes-Tack-Over-Liquid-Glue/dp/B083DSR3PT/ref=sr_1_4?keywords=tack-it&qid=1636818136&sr=8-4 The M5 nuts are used inside the case to secure the feed tubes in place. DISCONNECT ALL POWER BEFORE BEGINNING This conversion requires the removal of all bolts that hold the base plate in place, so it can be lifted enough to work under.CAREFUL There are cables connected to the base plate, lift carefully once all bolts are removed and find a way to hold it ~6 inches up (I used a shoebox). The base plate cannot be removed until the aluminum cover for high voltage components and cables in the back right corner is removed completely. Once the base plate is free and lifted enough to allow you to work under it, use the Material Plate Drill Jig to drill initial holes through the outer shell. Watch inside the printer to ensure the drill bits never get close to any cables or other components. Then open up the holes so the OEM tubing will fit through. Deburr all holes on both sides before putting tubing through it. I found it easier to pull OEM feed tubing at the print head assembly until it can be fed through the drilled holes. Attempting to simply re-route the feed tubes without removing slack from the other end will end up bending/kinking the tubing. Connect the M5 nuts to the OEM feed tube internally, then feed the tube through the hole and the appropriate hole of the Material Feed Tube Plate. You only need ~6mm of OEM tubing sticking through the external plate. Connect the OEM tubing to the small metal ferrule then use the internal M5 nut to secure it to the shell. Once all tubing is secure to the Material Plate, cut excess OEM feed tubes at the print head assembly. That's it. Using Tack-It adhesive on the chip holder is optional. I already have it, so I use it but the clearances on the Chip Holder model will hold the EEPROM filament chip snug. Probably too snug, requiring a little post processing for a perfect fit. I've had no issues printing the chip holders with PLA+ but ABS is recommended. I've done tons of ABS prints (60C internal printer temp) and the PLA+ chip holders have not been impacted by it.
