Need help dialing things in.
So now that I have most of my HW issues solved, I am focusing on the filaments and the print quality. My edges are the absolute worst. Anything at a 45° angle looks like garbage left out in the sun. The top layer is about as smooth as a dirt road in rural Africa. And I get a lot of those bits and bobs everywhere. Usually, after printing, I can find many of them either stick to my extruder or spread out over the bed. Ringing or ghosting is prevalent even after running multiple shaper_calibrate.
Suggestions?
Spectrum ASA 275
240°
7 0° bed
0.6 nozzle
Superslicer
40% fan
10 second layer time
0.8mm retract at 50mm/s
Other settings in the photos attached.

pa is too high
or maybe not enough cooling
try this
1. set PA to 0 (jsut to test it)
2. set overhang speed to 50
3. more cooling
tis looks also overextruded
EM tuning is a good idea
I'll give it a go in a minute. Thanks for the tips.
My PA was at 0.005. Turned it down to 0.000. EM is as low as 0.9 using the squares method. I'll post photos and videos of the EM squares below. My extruder steps seems to be fine. I tell it to print 100 and it prints 100, so all seems ok. I also stepped down my speeds all the way from 200 to 100mm/s and the acceleration from 15k to 5k.
i have never seen such bad surfaces
there is something totally off with your profile
I know 😦
And I can't figure it out.
I have tried profiles from other users and tried to tweak them.
To me, 0.9 seems like the best spot.
top infill 75% ??????
I believe so. Let me double check.
no need to check, i am asking your why you are setting it to these unusable values
75% means that you want to create a line that is smaller then the nozzle diameter
Because I am desperate and have tried everything else 😦
some other values are way to high
I have tried all the way from 100 down to 75.
dont play with your line width settings, set them to the defaults
100% or 0.6. Also tried. And will do it now again. I'll come back with the new batch after the test.
to start with, just use 0.5 for all lines
The nozzle is a 0.6
Will that not make a difference?
a what?
then use 0.6
Sorry... num lock.
i just have seen you are naming your profile 0.5mm
ahh no, stuipid photo instead of screenshots
nvm
I'll leave the EM at 0.9, which seems to give me the best surface, and set all lines to 0.6 and print out 3 squares.

What parameters do you change when use 0.6 nozzle?wall from 0.4 to 0.6 any other?
In this case I have already tried so many things I am pretty sure the profile I am using is broken.
In any case, here is the most recent print. After @Helge Keck suggested it, I set all widths back to 100%. After first print, sorted out EM and PA back up to 0.005. Consistent with the last PA pattern test. Solved top surface, but messed up the corners again.
turn PA off for the test, just to rule that out
tiny bit overextruded
The surface is actually better than it looks.
So adjust EM, right?
I'll adjust that before I start messing with PA again.
turn PA off until you sorted out your walll issues
Left to right, zero PA and EM at 0.80, 0.85 and 0.90.
Second photo is the under side, where I notice the first layer seems to have some gaps, not visible when putting down the layer.
The last one was mismarked. It is 0.9.
0.85 seems to be the sweet spot.
now print a test cube
the xyz one
its a quick print
make it 40 mm big
with the new EM value
Will do.
Still printing, but you can tell the infill is crap and on the edges it has this serrated effect. Will take clearer images once done.
thgese are probably just the seams
control it with our slicer preview
So... No change from previous settings. Straight up just loaded cube and hit send. Gaps on top. And the serrated issue. Happens on almost all edges. Not seams as per slicer preview.
Did you figute out what caused this?
