So far so bad… this printer is driving me nuts with the out of the box issues (mostly all software it seems…)
Has anyone else had the issue with the waste chute plugging/jamming during multicolor prints? I cant seem to leave it unattended for more than a few hours before inevitably its plugged up. sometimes the AI detects it and pauses the print, other times it just slams the print head into a giant lump of filament goop piled high in the waste chute and errors out the entire print.
Any community ideas for some fixes, after all, we certainly cant expect @CREALITY to actually provide a fix for their expensive product it seems…
Had only one time that the waste was blocking in 17 printing days. maybe you can clean and try some siliconen spray to smooth the surface of the waste chute.
Check the bezel arm isn’t bent. Mine was, which meant the bezel wasn’t lifting into it’s proper position. It’s a physical operation - the extruder head pushes on the arm to lift the bezel, the nozzle purges filament onto the raised bezel, then moves away and back a few times to do a Taylor Swift impersonation…
…yes, Shake It Off…
If the little arm is out of place or bent, this could be the source of your clogs. Also if the pin that it rotates upon is bent, it may not drop as quickly as it should.
However some extreme colour changes may cause high purge volumes which is possibly (I have not confirmed this) more than the bezel can hold without filament backing up into the nozzle. Things like red to white, black to white should be avoided if you can…I’ve worked in a few companies with coloured products and colour cycling is a well known practice to minimise cleaning/down time.
Also, give the little lever a press to the left; the bezel should lift up into place with no resistance; if it’s stiff or doesn’t drop back down completely freely then the bar may be bent. You could try straightening it yourself though in my experience getting the level of “true” required is impossible without a proper engineering shop…vices, clamps etc.
This is precisely the problem I’ve been having since the machine was new. Where can I find a new bezel? I don’t see it listed here: K2 Plus Parts List | Creality Wiki
Perhaps you could try a waste chute modification (which is usually 3D printed). Search Thingiverse, Printables, etc., for “[Your Printer Model] waste chute upgrade” or “poop chute mod.” Many users design chutes with: Steeper angles. Wider openings. Smoother internal surfaces (sometimes achieved by printing orientation or post-processing). Features to guide filament better.
I experienced this problem yesterday and for me it was two things. 1. The metal that the extruder pushes is bent. I just used a long nose plier to straighten it. 2. I noticed that the chute that I printed is a bit tight. Since it’s enclosed and the area that the poop lands is flat, sometimes the poop gets trapped there until it piles up and eventually messes up everything.
For what it’s worth.. I’ve had my K2 Plus since June. I experienced a major waste clog a couple days ago. The lever on the bezel was bent, as was the platform supporting the wiping spring & brush on the other side. I reached out to customer service, and they sent me a complete replacement free of charge as my machine is still under warranty. It was a bit of a pain to install, as I had to remove the back panel, as well as disassemble the replacement. I had to remove the wiping platform as well as the little cotter pin which holds the axle the bezel in. But, it’s in place and as of now seems to be working a bit better than the original.
I just got my printer, and turns out the bezel was installed incorrectly by the factory, and when I did a multicolor print it ended up dragging some plastic from the chute into the bezel, bent the bezel up (since it was backwards), and started hammering it, ruined the nozzle (and of course the bezel).
