With the Bambu P1S and a 8mm nozzle and 0.48 or 0.56 layer heights I kept on having issues with filament not sticking to itself while printing so I created this model to test out what would fix it.

You print this model like a pyramid.

You can also cut it so that it's not as tall but this is a pretty small height.

Unfortunately, the only solution I found so far is Scarf joint seam plus Scarf around entire wall with Scarf joint for inner walls also enabled but this can increase print times by up to 25% depending on the model.

For now I've stuck to 0.4mm layer heights which doesn't exhibit this issue.
