L.A. (Linear Advance) for the core One help request.
Ever since I swapped to the DiamondBack 0.4 nozzle, I have noticed gaps in the corners of prints using PETG. On the previous Mk3 this was fixed with an LA calibration print and subsequent setting the correct value.
What is the procedure for carrying this out on the Core One.
And storing the values.
Thanks.
Also would like to check the Extrusion calibration in case this may be the actual issue although prints do appear to come out the correct size so unlikely this.
Normal people believe that if it is not broke, do not fix it. Engineers believe that if it is not broke, it does not have enough features yet.
RE:
Core One doesn't have Linear Advance, I believe in this case is pressure advance. Also, if something is not directly supported in firmware then it can't be stored and has to be injected in the filament g-code.
I use the same nozzle and started noticing the same. I came across this the other day but haven't had a chance to try it out yet: Prusa Slicer Pressure Advance Calibration

RE: L.A. (Linear Advance) for the core One help request.
I tested this project just last week. It needs some manual work for preparation, but I'm quite happy with the results.
In my case it was not because of the nozzle, but it seems either PrusaSlicer 2.9.3 or some filament profile update changed the LA/PA parameters for the filaments I use. For PLA, the K-value changed from 0.022 (the default) to 0.03, and prints look much better now.

Linear advance and pressure advance are the same thing, functionally speaking.
The advance settings are in the filament profile gcodes... so changing the filament configurations may have changed the preset values.
