Cube 3D printer hack lets you use bulk filament


[Chris Nafis] crunched the numbers and found out he could get filament for his 3D printer in bulk for about one-fifth the cost of the cartridges the company sells. This led him to print a feeder for his Cube 3D printer.

We’re skeptical about the Cube 3D printer’s cartridges. They contain a spool of filament, but also include a chip which reports back the filament color and length remaining. We’re sure this provides some nice functionality for those looking to press a button and walk away. But we see it as an annoyance like the laser toner cartridges that stop working based on page count rather than remaining toner.

The solution [Chris] went with still uses the cartridges to ‘trick’ the machine into printing. Basically the interface will tell you that you don’t have enough filament left, but as long as there’s a cartridge in place you can tell it to print anyway. The green adapter he printed has a pass-through for the stock cartridge as well as the bulk spool you see to the left.

    Anyone has the firmware file for v.2.0.7 ? I flashed the v.2.0 but wanna get back to 2.07.

    No denied this hack somewhat work with certain revision of firmware. I found much better hack from this site, according to Dan this will work with firmware v2.07 on his machine. Here is the link:

    Hi!!! I am having problems when extruding the bulk filament, it seems and i have tested that the cube extruder heats only to 150/180 C celsius and the filament i am using melts at 210 C.
    Does anyone have the same problem???
    And any idea on how to solve it???

      Maybe is not a problem of the temperature i´ve since y was measuring the temperature of the exterior and it varies, for example my witbox has an exterior temperature of 120 when the termoresistor shows 220C, my problem is that the filament gets stuck and doesnt flow, also the motor makes noises since it is trying to push the filament, i´ve measure the with and its the same as the cube filament so i dont know what else it can be.
