In order to unblock the 3Doodler PRO, insert the thick unblocking tool into the rear of the pen while it is turned on and fully heated up. Be sure that the nozzle is taken off (with the pen turned on and heated up), and also ensure that the temperature is set appropriately for the specific filament that is clogging the pen. The aim here is to push any material inside of the pen out through pen tip.
If this doesn't work, please insert the think unblocking tool in through the nozzle end of the PRO, with the nozzle removed.
Do not force material out of the pen. If it is not flowing smoothly try adjusting the speed or temperature, and always reference the recommended settings for each material.
