I’ve been having problems with a 3d printer that I recently got, the FlashForge Creator, and the left extruder has clogged, but when following a youtube tutorial that will fix it, the filament will not go out the left extruder, it is a blue PLA filament that came with the printer, the heat settings were 230C for left I have tried manually pushing it through, but it will not go, I believe it may be the extruder not heating up properly. I do not know what to do, and I have attempted to contact the manufacturers support email a while ago and still have not recieved a email.
