If you have spent more than five minutes in a 3D printing Discord server or scrolled through the dark depths of r/FixMyPrint, you have likely encountered the phrase:
A blobby boi occurs when extruded plastic fails to adhere to the print bed and instead sticks to the heated nozzle. As the printer continues its programmed paths, it keeps pumping out filament. With nowhere to go, the molten plastic curls upward, wrapping itself around the heater block, thermistor wires, and nozzle. The root causes generally boil down to three main culprits: 1. Poor Bed Adherence ext printer blobby boi
Turn on your printer and heat the nozzle to the printing temperature of the material that made the blob (typically 220--250°C for PLA/PETG). Let it sit at this temperature for 5-10 minutes to allow the heat to soften the plastic from the inside out. If you have spent more than five minutes
It can destroy the thermistor (temperature sensor) wires, rip heater cartridge wires, and ruin the heater block itself. 2. Common Causes of the "Blobby Boi" The root causes generally boil down to three
