I had my Da Vinci Jr 1.0 turned off for a while And just turned it back on in an attempt to print something for my sister, and when i told it to load the fliament, it gave me an error 0014. I looked it up and it is an error with the extruder heating. I tried to fix it by checking the connections and rebooting the printer, but to no avail. Any suggestions or fixes? The printer is refurbished, so I have no clue if that is the problem, or if it is just the hardware.
