Hello,
i would like to measue the length of filament after extrusion out of the extruder to check how many meters filament i extruder and spool on the filament spools.
Is there any solution availabe to measue the length and report it on a display based on arduino?
Sure. Wrap the filament around a spool and count the turns of the spool. The count times the circumference of the spool is the length of filament you have created.
if you has a mechanism which react on movement of filament, then you can easy convert mechanical movement to electrical impulse which Arduino(or whatever) can count
