Greetings,

I've been trying to get some finer details tuned but it seems that I have reached my achievable pinnacle and would appreciate any recommendations to better the final product rendered. Granted, I am happy with the results thus far and have no major concerns, just looking to make it 'more better'.

The printer is a MK3s running FW 3.9.0-3421 with a Bondtech Mosquito extruder and a Microswiss 0.4 nozzle. I've attached images of the calibration cube, linear advance results, and Simplify3D settings.

Any pointers or help is much appreciated!

BLUF: Switched LA1.5 to 0.15 and made ~80% improvement.

I made some progress. When I did the initial LA1.5 test pattern it was in the 0.0 to 2.0 default scale. In this scale, 0.2 is the best line. To further refine the findings, I performed the test again but at 0.0 to 0.4 to drill it down to get the best fit. After I inspected the results (along with others) the 0.2 line was the best again so I began using it. The performance was good, but artifacts were presented as noted above. Then as I was troubleshooting and trying to resolve the corner artifacts I change LA1.5 to 0.1, 0.3, and back to 0.2 - and again, 0.2 was the best-observed results. Before leaving my house this morning, I looked at my digital notes with pics and thought that 0.15 on the expanded test looked best - it is funny though because the actual print to eye appeared to show 0.2 as best (3 people), but the pic shows 0.15.

So lesson-learned, when performing half-step troubleshooting with LA1.5  numbers, step at no more than 0.05.

LA15 @ .15 is more correct

After some experimentations, an X/Y Jerk value of 8 gave some further easing of artifacts. The latest firmware has 10 predefined and would not let me change the value for either X or Y, funny enough E could... I used the terminal directly to change the value but M503 showed that it would not take in the X or Y axis. Not a big deal, just changed it in the configs, enabled Live-K, and recompiled easily on linux using ./PF-build.sh. 

Follows is the best possible S3D FFF profile that I could refine for eSUN Black PETG.

Note: Depending on the object to be printed, layer start/stop gap/seam can be reduced by unselecting "Force retraction between layers" under the 'Advanced' configuration tab, in the 'Ooze Control Behavior'. Additionally, you can change 'Start Points' under the 'Layer' configuration tab.
