Hello, I just joined! I purchased a prebuilt Big Box and it worked nicely for about 15 prints right out of the box. I started getting a problem where the melted filament would back up into the heat sink, and clog the printer, strip the extruder, etc. I decided to switch out to the volcano. After carefully following the assembly directions and turning it on, I get a MAX TEMP error. I don't know where to go from here. I have a multimeter but can't quite figure out how to check the resistance on the different components. Can someone please help? I would really appreciate it!
