I have read that each slicer does things a bit differently here. For example if I have a 1mm wall and a 0.4mm line width some slicers would do two 0.4mm lines AND an additional line to make that 1mm wall and sometimes over extrude.

I could imagine another slicer deciding to do 2 0.5mm walls IF the nozzle can support that line width.

But is anyone familiar with Bambu's rules here? This comes into play for me when I am trying to create tight fits between thin parts. Especially when using the larger nozzle where my goal is to try to have max one or sometimes two loops representing my walls.

This also gets confusing to me when I set my wall thickness in cad to exactly the line width. For some reason often Bambu just gets rid of those walls. I have to add a small epsilon to that. But what does that mean for the fit of the part?

A concrete example to understand would be:

If I had a line width of 0.5mm how would the slicer treat walls of:

0.501mm

0.7mm

0.9mm

1.0mm

1.001mm

1.2mm

I have ran each of these examples through the slicer so I can see how many lines its giving the walls but I cant tell how its "biasing" those lines it puts down so that they either are or aren't accurate to my target wall start and end if that makes sense. It could matter for a complex fit if it decides to take that 0.7mm wall and draw it with 2 0.5mm lines by shifting the whole wall 0.3mm to one direction.

Is this something the more advanced slicers like Orca have better transparency or control into? Its really difficult to tell when the slicer has essentially moved or changed my geometry to fit the slicer constraints.
