I just received my K1C yesterday afternoon. I had a lot of problems getting filament to feed past the sensor. Eventually I figured out an angle that worked. Oof, but that’s not the key issue.
The real issue is that since the first print, I seem to randomly run into an out of filament error. Here’s the run-down.
From the printer:
600S Test speed print test. Out of filament warning half-way through the print. Visually inspected seemed filament was fine so I pressed resume and the print completed.
Benchy, paused halfway through saying out of filament. This time re-fed the filament as if doing a spool change. Pressed resume and the print completed successfully.
From the Android app:
Tried to print the toolbox for the included tools. Immediate out of filament error.
Tried to print a second toolbox, different file, and again immediate out of filament error.
From Creality Print 6 on Windows:
Printed a USB cover for the printer just fine with no issue.
Printed small caps for my aerogarden unit with no issue.
Began the print of the toolbox. No error on stating the print. Went to bed last night and found the print again stopped for an out of filament error a little more than halfway through. I was once again able to press ignore and resume and complete the print.
I’ve done everything I can to make sure the filament is moving smoothly through the tube and that the spool is freely moving on the holder so I don’t think it’s binding up and having trouble pulling it in.
Bad sensor? Bad freebie filament? Something else?
I’m about to try some prints with some Bambu PLA I got so I’ll be sure to report back if that somehow fixes this problem. Thanks for any help or insight you can provide!
It could be the filament sensor is a little wonky. I would try to bypass the sensor on a test print to see where the problem is. Stick a piece of filament in the sensor just to keep it happy and then run your print filament straight through to the extruder if you can without going through the sensor.
Another thing to check could be the connection going to the sensor. Not sure if it’s the same as my K1 Max or the Ender-3 V3 series but a loose connector can cause intermittent problems.
Ah! Excellent idea to bypass to test if it’s that sensor or not. I’ll give that a shot. Thank you for that guidance!
Anecdotal but I just did another somewhat larger print, swapping the free Creality Hyper PLA for Bambu Matte PLA and after dialing in the temp, I was able to successfully complete the print without interruption. So initial evidence is pointing to the included filament being bad somehow.
I’ve got two more slightly larger pieces to fire off so we’ll see if the filament swap holds or if the issue returns.
I just unplug filament sensors to bypass, I think the only other easy way is throught the fluidd interface- not sure if the K1C has fluidd by default at the printer IP and port 4408
Problem solved I think. The error at least on trying to print from the printer and phone appears to be a faulty sensor. On the printer it constantly shows a yellow broken filament icon.
However I believe the out of filament mid print was due to the free filament being bad somehow. I’ve now used a new spool of Bambu White PLA and second spool of Bambu Green PLA and I’ve finished 4 longer, bigger, multi-hour prints without issue.
I guess I’ll be talking to creality support about replacing that sensor.
