Are there quantitive means of measuring nozzle wear? What steps do you perform to measure this, if so?
I have some digital callipers, but don't have much confidence in measurements taken, as it's almost impossible to ensure the nozzle aperture is completely free of filament residue.
The context here is I've recently been trying out some carbon-fibre infused PLA filament, but would like to keep an eye on how much it wears the nozzle, and get an idea of nozzle wear rates. I can then work out if the mechanical and aesthetic qualities of the CF filament are worthwhile.
