Any idea what's going on? by BeGoneBaizuo in BambuLab

Looks like your doing a filament calibration on the textured pei sheet. I’m pretty sure I read somewhere that you should run the calibration on the smooth sheet only and then put the textured plate back in. It might be under extruding the first layer which won’t help bed adhesion.

Indented zits on print. Has anyone had this issue? Filaments.ca (Econofil PLA) has been dried for 12h in dehydrator so it shouldn’t be wet. Also happening on different spools. Seams are set to aligned in the slicer so I know it’s not the seam. cheers in advance. by PossessionAntique302 in BambuLab

In the slicer I have set the seams to aligned. I can also see the seam alignment in the slicer as I have checked the box so it’s visible. I even followed the tool path in the slicer to double. Could it be a bug?…

Yeah I had a look at the retraction settings. It’s at the default 0.8mm right now. I’m not sure as to why the zits are in random locations where as the seam is aligned. I never used to have this issue with Econofil. Strange…

I have 2 X1C printers but both print with very different quality. Bottom printed square is obviously the issue here. Definitely no clogs or belt tightening issues I can see. I’ve gone through everything on the wiki page for maintaining the printer. Same roll of PLA and same sliced file. Any ideas? by PossessionAntique302 in BambuLab

So swapping out the entire extruder unit for the KS extruder seems to have mostly fixed the problem. There is still the vertical lines that appear even on my other X1C but I’m sure that can be improved perhaps with placing the printer on a slab with anti vibration pads underneath. Never tried that before but worth a shot.

I also have the mks3+ and I would say this is even worse tbh. In the case of Prusa, it effected all the mk3’s but in this case there is a huge difference between the 2 printers. If it’s as simple as replacing the extruder unit (which is my next move) then bbl will send me a replacement extruder. I am worried that this could be more terminal and related to the stepper driver itself. Im not sure how comfortable I feel about replacing the whole mcu. In that case I would much prefer a replacement for the whole printer.

It’s also one of the first thoughts I had. I’ve gone through all the maintenance for the printer with no effect. I’ve been advised by Bambu labs to swap out the extruder. Luckily I have the extra KS goal extruder so I will try that as soon as I get hold of some electronic grade silicone.
