I’m trying to calibrate linear advance on my anycubic kobra 2, using the guide in this video. I have calibrated my E-steps and flow rate for the extruder, and get the expected 100mm extrusion and expected wall thickness…so far, so good.

When i attempt the LA calibration to find my K value, i get the result shown in the image, with a serious deterioration of line quality when LA is enabled (K>0), and it seemingly gets worse as the K value increases.

I have used the tool from marlinfw.org to generate the g-code for testing K values.
