have been several users including myself with filament cartridge issues, and
several posts about it in the CubeX user group, I thought I should post about
it here with some possible temporary help to keep printing.
help you to get by and use a problem cartridge.
(Attempt at own risk).
cartridge has a little chip at the bottom where the filament exits, that makes
contact with the CubeX when the cartridge is installed. The chip contains
information about what type of cartridge it is and possibly records the amount
left in the cartridge.
If you have a
cartridge read error, you should check
that the contacts in the CubeX and on the cartridge are clean and try to
re-insert it. If that does not help try the cartridge in a different cartridge
slot if you have a duo or trio. I have had only one cartridge read error and it
went away when I re-inserted it a few times. Otherwise I don't have more help on that
one, except power cycling the CubeX and trying again.
cartridge is binding (filament won't pull out easily) and or you are getting a
filament flow error you can carefully open the cartridge and run the spool
(Note: A filament flow error might not always be
due to a binding cartridge.)
In some cases the filament is wound up crossed onto the spool and hanging the spool externally won't help either because it keeps tangling on the spool. (At least you can see what is going on with the spool hanging externally). In that case unwinding and rewinding up the filament on the spool is the only fix.
careful to not damage the chip at the bottom of the cartridge, and careful with
the inner cardboard spool since it is only lightly glued together.)
Here is what I did:
This has worked great for me with the 3 cartridges I had binding issues with. One I had to glue the spool back together, but got it useable off the external hanger.
cartridge out of the CubeX.
Use a exactor
knife to cut the label at the cartridge seam.
To open the
cartridge, start at bottom of the cartridge next to the chip. Insert a small
flat screwdriver to release the clip next to the chip. Try to keep the chip in
Then do the
same on the clip next to it and move all the way around to open the cartridge
take the cardboard spool out. Handle the spool with care so it does not fall
apart, since it is only lightly glued together.
spool is taken out of the cartridge, make sure the chip is in its place (if the
chip fell out, make sure to position and orient it correctly, otherwise it won't
make contact with the CubeX) and then close up the empty cartridge (with chip
Also, when removing the spool from a cartridge, make sure to write onto the spool, which cartridge it belongs to, so you don't get them mixed up if you have multiple cartridges of same color etc..
cartridge can now be inserted back into the CubeX.
spool and how the filament is wound up on it. You might have to unwind some
filament, where it is bound or tangled up, and then loosely wind the filament
back up on the spool.
For the cardboard
spool, you need a holder with a smooth rod so the spool can rotate on it.
Here is a
hanger you can print yourself (in PLA), but you also need a smooth 1/2"
rod (should be very smooth / polished) with 8-32 threaded holes on each end and
two 8-32 x 1/2" SHC screws and washers
and one large fender washer.
filament end, and make sure to get a clean cut of the filament so it will feed
in properly. The filament should be still round at the end after clipping it.
If not, you can use a exactor knife to slightly taper the end of the filament
which might help feeding it back into the guide and filament feed motor.
prepping the filament end, you can then just feed the filament directly from
the hanging spool into the filament guide in front of where you inserted the
cartridge replace menu. (You can leave the empty cartridge in place during the
filament is feed thru and extruding , you are ready to go.
If you have
problems feeding the filament and the motor won't pull the filament in, go into the menu with the 240C icon.
There you can heat up the jet by double clicking on the TGT temperature, it
will toggle between 0 C, 195C and 230C. Use 230C. Then you can
double click on the feed speed to get the motor feeding at different speeds, 8
or 12 should work.
Keep pushing the filament in, pull
in and out, eventually it should go.
I had a difficulties last time at a
filament change, but eventually after I re-cut the end of the filament again,
it feed in ok.
After using the cartridge, I stick it in a plastic bag with the desiccant from the cartridge, till I use it again.
