Printing the diffuser in PLA on textured bed with bambu glue applied. I am getting an 8cm extruded tail which I noticed about half way through the first layer (tail had stuck to the side of the print head and was moving back and forth with it). I paused the printing and it wiped it off. When it restarts the print, when it moves back into position there’s another one stuck to it (did it three times). Sorry if the terminology is incorrect but am very new to 3d printing. I have had the x1-c for about 3 weeks and haven’t had any other problems with it.
In the photo the lumps in the foreground are where one of the tails had been overprinted and I paused and cut it from the print. When I resumed the print you can see the new tail it produced and which got stuck to the print and had to be cut off (that one I did it while the printer was running to avoid getting yet another tail).
The filament is being printed from the AMS with three full cages of dessicant, the AMS status says the moisture level is “1”. The filament is Bambu PLA and is being printed with all standard settings in the slicer.
Can you tell me what is causing this and how to stop it?
As for the temperatures, I’m not sure where those are set. I’m just using whatever the slicer decides for Bambu PLA Basic filament. If I edit the filament settings in the slicer, under “Print temperature”, and “Nozzle” it has First layer: 220 C, Other layers 220 C. Is that what you wanted?
Is there a better way of providing this information? I considered attaching a 3MF file, but I think that contains the model as well and that could be copyrighted?
Indeed but despite now having this info it does not help.
You should not get these issues.
It is as if the infill line or a wall line did not attach to the print but I can’t see anything missing in the pics.
Are you certain these tails are not a leftover that got stuck during the purging ?
Try to ramp the print temp up to 230 degrees and see if this makes a big difference.
If so print a temp tower or all in one test model to hone in on the best temp for the filament.
After that do the flow ratio calibration and K-factor.
If the print then still fails we have to get creative here.
Some users will post multiple screenshots showing all of the many possible settings. It can be rather tedious to review and compare to settings that work for me. (I usually skip over those posts entirely.)
I prefer to use the Compare Presets option in Studio:
This shows only the differences between presets. This makes it easier to compare presets to default settings, or to try similar settings on my own printer - no need to verify every possible setting.
I tried running the same print again (same settings, same model, same filament), but I didn’t get any tails. Thinking back, I believe I’ve had this happen once before about two weeks ago, so maybe it’s an environmental problem? Either way, without being able to reproduce the problem again (was hoping to catch it on camera to show exactly what happens), it doesn’t seem like testing changes will help.
I’m going to just keep an eye on it for now and wait to see if I can catch it in the act again. Thank you for your help.
Print problems can be caused by all sorts of factors, eliminating them is the hard part of the game.
Quite often it is the filament not being dry enough, a cold blow of air when someone leaves the house or opens a window to let some fresh air in.
At other times it be as simple as a flaw in the filament…
3D printing is a never lending learning experience and should never take perfect prints for granted
Enjoy the learning if you can and you will see it does not take much to stay on top once you have the experience to judge how a problem might relate to causes.
