Extrusion multiplier calibration
Good evening everyone,
I am currently working on the topic of “extrusion multiplier calibration.” I printed a 40x40x40 cube and measured the walls with a caliper, which gave me a value of 0.052 mm.
How should I calculate the extrusion multiplier? When I calculate 0.45 / 0.052, I get 8.6538.
I have no idea what value I should enter for the extrusion factor.
Can you please help me with this?
Thanks and best regard

I take it that you followed this guide? https://help.prusa3d.com/article/extrusion-multiplier-calibration_2257
You are on the right track. I think you simply read your calipers wrong. 0.052 mm would be an extremely thin wall, the thickness of a sheet of paper. (And pretty thin paper too!) It's probably 0.52 mm? In which case the multiplier would be 0.45/0.52 = 0,86 = 86%.
Maybe measure again in a few spots. If it's 0.52 instead of the nominal 0.45, that is a pretty significant over-extrusion. But if that's what you measure, try the 86% extrusion factor and see whether that gets you to the target thickness.
