Linear Advance Live tuning test model
Designed a model with a high and low speed area to tune the k-factor.
Slice the model with a wall count of 3 lines and choose a line with of 0.6-0.7mm and a layer height 0.25-0.28mm for good visibility. Choose a high printing speed e.g. 60-70 mm/s or the most used printing speed.
-Added a thinner model as some people like thinner walls. (Not tested)
When slicing avoid the small green triangle as this will slow down the speed and mess up the nice lines (see last image sliced with cura). Prusa slicer seems not using those triangles.
While printing the model, you can tune the k-factor watching how the small half circles and corners are filled compared to the rest of the wall. k=0 gives a full fill and k-factor bigger than 0 gives less filling, tune it in such way that the lines look everywhere the same. Start with large enough steps to see the changes.
Value's found on my Ender5pro with shorter bowden setup with all metal hotend using PETG filament.
