Hello.
After a couple of prints, my new X1C/AMS pulls filament onto the heat bed.
ePLA-ST from eSun printed with included eSun PLA+ profile.
In two cases it ruined the print.It’s not every time. But increasingly often.
Now I noticed, that after the first layer, the head moves back, after a couple of seconds it wipes the nozzle and then a piece of extruded filament sticks to the nozzle and gets pulled onto the plate.
Anyone with the same problem? Any help is appreciated.
Kind regards
Roland
I find this happens more when there is plastic stuck to the nozzle. Making sure the nozzle is clean I find a get a lot less filament that sticks to the nozzle after the wiping procedure and is dragged into the print surface. A light brush with a brass brush while the nozzle is hot can remove anything sticking to it.

Hi Jon.
The nozzle is very clean. For me, it looks like the wiping procedure doesn’t work properly. But I am not very experienced with Bambu printers.
Hell… if after a few weeks, the bottom of your printer isn’t looking like a bird cage, you’re not printing enough.

Your chute may be clogged and it’s dragging poop out. What is that in the back that looks like it’s covering the chute? Doesn’t look like a standard wiper either. Can you post a clear picture of that area?
Are your bearings escaping?

No. Those were test prints that I popped off the plate and was too lazy to retrieve.
I printed four at once and after the second one measured perfectly, I just popped the others off the plate and forgot to retrieve them. Call me a slob but there’s a lot of surprises I find in the bottom of my Bambu Bird Cage each monthly cleaning.
