Filament: length ↔ weight
E-steps calibration
Mark the filament, extrude 100 mm while hot, then measure what actually went through.
Flow rate calibration
Print a hollow single-wall cube and measure its wall with calipers.

FAQ
How do I price a 3D print?
Add filament, electricity and machine wear, add a margin for failures and labour, then your profit margin.
How many metres are in a 1 kg spool?
About 330 m of 1.75 mm PLA. It depends on the material density and diameter.
Do I need to calibrate e-steps?
Rarely on recent printers. Do it after changing the extruder or if prints are under-extruded.
