Running into a bit of problem with the extruder on the 3d chameleon not being able to push the filament through the PTFE tube to the Y splitter for loading using the hold for 5seconds then pressing to move the extruder forward. It always seems to either slow down or occasionally pushes it or out right looses grip, the extruder is not stopping it just seems to not have a good enough grip and slips. I am having it push through the entire length of the PTFE tube that is with the kit, is that perhaps to long??
I'm just using a normal PLA
Any help is much appreciated! I'm looking forward to printing!
I am experiencing this problem of the tubes being too tight as well. Just as an additional note, I have the 8 line system and both sets of tubes are too tight.
I'm having the same issue. When the gears do get a grip, they just end up pushing the tubes out of place. I've tried multiple brands of filament and the tubes are just too tight without enough grip and without enough hold to stay in place.
Sounds good. Ill go ahead and email info@3dchameleon.com to arrange that. Would it be any interest to you to have me send back my set of tubing for you all to take a look at?
Thanks for all the help.
Not sure what exactly is happening... but we can send you a new set. Bill
So, just the basic tubes at too tight. You need to check the diameter of your filament... Standard filament is 1.75mm +- .3. If it is outside that, then it won't work... as our tubes are 1.82+- .3.
Optionally, you can try a different filament that has a known good quality... something like Prusament.

A few things. Can you check that the filament is easy to push through the tubes by hand. There should be virtually no resistance to pushing it. If there is, check that the tubes are not bent/kinked. It's possible the crimp in the 4mm brass ferrule is too tight... if that's the case, try using a small drill (about 2mm in diameter) to open it up. No need for power tools here... you should just be able to turn the drill bit by hand. Also, check that the alignment of the drive gears is perfectly centered with the tubes on the extruder motor end. If they're not aligned, you'll get exactly that. Lastly, check that the cam is positioned at exactly 6 o'clock position when it is homed... if it is not, you need to reset it by holding the button for about 22 seconds... it will respond with 3 short vibrations of the selector motor to indicate that it was reset.
