45° miter cuts not forming a 90° corner on skirting boards - what am I missing?
I recently bought a basic miter saw (Metabo KGS 216 M) for small projects around the house. As far as I can tell, the saw is well adjusted - the blade looks square and the angle stops seem accurate.
Right now I’m cutting skirting boards, and I’ve noticed that some of my 45° cuts don’t form a clean 90° corner when installed against the floor. Instead, the corner ends up slightly off.
I’ve attached photos showing one example and what I expected the corner to look like.
Is there something obvious I might be missing when cutting skirting boards? What are the first things I should check on the saw or in my setup?
