Is the X axis gantry level? You probably need to raise your Z-end stop switch just a bit so you can tighten all of the knobs further.
He needs to loosen the knobs 
fixed it. I raised my extruder, loosened all knobs. Lowered the extruder while tightening just the knob on the bottom left so there is just a small gap between them. After that moved the extruder to the right, while tightening down the bottom right knob until it fit. DId that with the other 2 and then proceeded with the standard leveling procedure.

Smart compact temperature calibration tower
You’ll need to add g code to adjust temperature at various levels of the print with this. Depending on which slicer you use, you either accomplish this with slicer settings or a script.
Once you find the optimal temperature, you can calibrate retraction with this Google Sheet and tutorial:
Other thing i have is a seam where the printer changes walls i assume. Is that something i can fix? (sorry for the dust 
)
Got some cleaning to do… might have happened due to the heatbreak leaking. However, I hope its from a print that came loose a few weeks ago

Ah, that’s the reason I’ve never done one… idk how to do that 
haha
- Z seam alignment options
- you can force it to hide the seam on the inside, outside, on the sharpest corner, or randomize it (best for round objects imo)
- Enable coasting
- cuts the extrusion off early on long extrusion paths and uses the bowden tube built up pressure to account for oozed overlap
I’m currently dialing in my settings to deal with unwanted seams and zits and this has helped most.

Shoot me a PM and I can help generate the g code. 
Ah i didn’t even have those settings visible. Which one of them do you prefer?
and this is what i have for coasting (also hidden so i never changed anything)
Depends on what I’m printing. Hide seam or smart hiding usually does a good job but sharpest corner makes for an easy seam removal. Round shapes look best with the random.
Is your seam bulging out or dipped in compared to the walls?
Direct drive?
Bowden drive (stock ender 3)
The top photo makes me think you should turn coasting off.
The second photo just scares me. Is there an unwanted bulge like that anywhere else on that print?
How does it look when you zoom in on the preview in cura?
@Alpacaslapper Nope just that line. I just looked at other prints, it seems like that bulge primarely happens on round objects. (need to check on cura)
These 2 have it on the same spot (they are the same print just one the longer version
tl;dr seems to be coasting that causes it (atleast if we look at cura on the bottom)
here are some more examples.
these for example don’t have that bulge
this one has it on the inside
cura on 2 things that are round :
coasting disabled

Try 40mm and 2.0mm
Set wall swipe distance to 0.2 or something close. You can see what it does in the preview. Basically moves the nozzle inward after completing the outer wall.
Coasting might help, but not too confident.
