XYZ Calibration Cube (20mm) corner artifacts, MK3s w/Bondtech Mosquito, MicroSwiss 0.4  

RE: XYZ Calibration Cube (20mm) corner artifacts, MK3s w/Bondtech Mosquito, MicroSwiss 0.4

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.

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.

RE: XYZ Calibration Cube (20mm) corner artifacts, MK3s w/Bondtech Mosquito, MicroSwiss 0.4

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.
