Cube 3D Printer bulk filament spool adapter by nafis Apr 18, 2013

Description

The Cube is a solid little printer. It is *very* simple to use. There are barely any “knobs” to tweak. It’s good for someone that just wants to reliably print things without babysitting the printer. The ABS does have warping issues even with the heated bed. The big problem is the filament “razor blade” model. The printer is not that expensive, but they charge $49/0.7lbs of filament! (compared to $31/2.2lbs of Octave 1.75mm filament). That’s 5X the price!

It turns out that you can by-pass/defeat the Dallas Semiconductor 1-wire chip which is located in each cartridge. The chip stores the filament color, remaining amount, etc.

This adapter allows you to connect the plastic filament tube and then connect to a spool of generic filament. It was printed on the cube (version 1)

Instructions

I'm still running experiments to compare the build quality using the Cube filament versus the different less expensive spool filaments.

I made a spool holder out of some 1/2 cpvc tubing:
1) three pieces of 6"
2) four pieces of 1"
3) two pieces of 3"
4) six T fittings
5) two 90 degree fittings

I hand drilled a hole so you can leave the cartridge filament hanging out. I will update the CAD models when I get the chance.

I don't have a cube, but wanted to say thanks for uploading this. These companies need to know this is not 1980 anymore. We are over having chips in our Toners and ink cartdridges and proprietary filament. The new XYZ davinci is another example. Cheap $500 printer, but the chipped filament carts are where the money's at. I worked with photocopiers for many years and have found just like here, people will always find a way to bypass their scheme for monopoly, which I encourage more people to do.
I found a link to the older cube firmware for anyone that wants to try this hack running newer firmware. I'm not sure how to load the firmware but if someone knows how please help by posting instructions.Link: drive.google.com/folderview?id=0By9lF8Q3EZlNeVdhZUZlV1kyS2M&;usp=sharing

My machine is Cube 2 with firmware V 2.05 and software 2.03. When use full cartridge and empty cartridge to fool machine, it does not work. When full removed, the screen show it is removed and then quit printing after 30 seconds.
How to get old version V1.10 ?

wow, just tested with all my fingers crossed on my first gen, no problems at all! can't thank you enough for the tip. i didn't have to even load an empty cartridge, just 'loaded' a standard one but really inserted my own into the print head and voila. (using octave plastic)
hi nafis:

can use the cube 3d printer 2nd generation?

This box can only print it!! so cool!!

What the note?

Downloaded this, but cannot get it to print properly on my cube.
n6mon, are you having trouble printing because of the orientation of the model? If so i was able to get it into the proper orientation and i will give you the model. Im going to try printing it tomorrow.
Can the adapter also work for the cube x model, if so how thanks
I don't think so.
hi, I have been wondering about the dimension accuracy of Cubify printer for a long long time already. No review about it. Do you mind try this youtube.com/watch?v=lQbvfiZAm-c for me?
any bets on how many days it takes 3DSystems to update the firmware :-)
Just under an hour...
What is the actual firmware version??
V1.10
gan - in reply to nafis
gan again. vi.10 is this for cube software or firmware? Same question as ofir36. how to find and install version v1.10
ofir36 - in reply to nafis
Is there a way to find and install this version ?

I tried the link. It does not work. when the full cartridge replaced by empty one. the screen says the cartridge removed and abort after 30 second. My cube software version is 2.0.3. Should I get older version?
how do you bypass the chip? after you exceed the allotted filament does the cartridge read empty?
I saw the larger cube-x at CES this year. It looked nice. Our local Maker group has two other DIY type printers. Some days it seems that you have a 50/50 chance getting a large job to complete successfully :-) I guess it depends if you want to learn about how printers work, or if you want to build things. Both are reasonable goals.

I think your design is brilliant and I can see how posting too many details might not be more helpful.

@andrewupandabout We are using our cube in a middle school setting. For our purposes it is a great machine. I recognize its limitations and have great respect for the diy/open source/maker ethos. But in a school setting I was willing to sacrifice some control for ease of use and dependability. It is extremely user friendly and is essentially plug and play. We have had it for about 6 months and are happy with it so far.
Nafis, would you buy another Cube if it printed a larger volume? Andrew (http://3dhacker.com)
I can tell you i wouldn't. The machines are fine but the company is slowest shipping company of all time. I have two cubes, and my orders usually take 3 to 4 weeks to be shipped. Sometimes longer. It gets really frustrating! Looking back my money would have been better spent on a makerbot R2
Thanks for the info. When I ask others they also mention unfavorable reviews. Andrew (http://3dhacker.com)
I'll post more details in a bit. The downside is that 3D Systems may change the hardware/firmware to eliminate the capability. What do people think?
Does the original cartridge need to have a certain amount of filament in it to bypass the chip sensor?
Yes, that's what matters! I tried to feed the bulk PLA, it printed whithout any problems, but after the cartridge should have emptied, it stopped with the "Empty cartridge" error!!! Please, somebody help us, it's so frustrating...! Any modified firmware or sg?
Does anyone know the answer to this question?
That trick only works on Cube 1 printer, to run external filament on a Cube 2 you need a device called Cube3DFree.. I have one and it works.
