I have a Neptune three Pro and within the last month every single time I do a print filament will come out for the first 30 minutes to an hour, but then completely stop giving out the filament, but the printing head will still move.
I have unclogged the nozzle, changed the nozzle completely, tightened up the gears and recently just replaced the whole head itself. And it’s still happening. Did I do something wrong?
