Recently started using dual extrusion module after about 2-3 prints it wasn’t feeding anymore, took it apart and the only part with plastic still in it was the hot-end module, try to heat it up and push the plastic though but that didn’t work, anyone got any ideas of how to unblock it?
Heat it up to 250°C and push filament through.
If this does not work it is possible to change the nozzle or clean it with a needle or something similar.
There is a lot of information and possible tools if you search the www.
this is what i do to fix it.
- cut the filament above the nozzle (right above where it identifies the nozzle NI0.4) and below the feeder lock.
- take out the hotend
- take your 1.5mm driver and loosen the set screw above the hotend nozzle
- disconnect the hotend nozzle wiring and grip the nozzle and pull. you may have to twist the nozzle to get it to break loose.
- most times the nozzle came out clean. once it came out with the jammed ptfe tube.
- get a pair of pliers and grip the filament without crushing or bending and pull hard. the filament will come out wrapped tightly in the ptfe tube.
- now pull the ptfe tube off the filament.
- reassemble hotend
- reinsert hotend
- do a z offset calibration
- do a xy calibration
you are done and ready to go

Thank you lots
more then welcome…
as an aside. the biggest reason i had for the right extruder clogging was the cooling properties of the module during dual color prints. does your module have the door with the expanded ports? if not you need the upgrade.
the other thing is the pins behind the hotend. they are fragile and can be broken when filament sticks and you wrestle the hotend out.

Thank you so much, really appreciate the help. Will look into getting that other door for it.
