To see if your nozzle is clogged, raise your nozzle at least 3 inches vertically off the bed. Make sure the nozzle is up to temperature (ex. ABS ? 240C). Release the Quick Release Latch on the X carriage. Manually push the material out of the nozzle, once it has fully heated up. The material should slowly protrude out of the nozzle. If it doesn’t, this means your nozzle is clogged. You have two options, clean on the nozzle by using the instructions on our website or buy the upgraded hot end.
