Changing the Nozzle
The nozzle of the printer may be changed without fully replacing the hot end. Changing the nozzle is useful if the nozzle has become clogged or if use of a different sized nozzle is desired.
To change the nozzle use a XXXXXXmm wrench to engage the nozzle and a XXXXXmm wrench to hold the heater block. If the nozzle is caked in plastic and can't be held with a wrench, then vice grips may be needed to perform this operation.
