CraftBot 3
Clogging is the most common problem in every 3D printer and cannot be prevented 100%, but if you
follow these simple steps you will prevent 95% of occurrences. If you still cannot clear the passage
with just this method, you may want to move onto the next method by following these next steps to
actually remove the nozzle itself…
10.2. REMOVING THE NOZZLE
On the original Craftbots before the CB3 you was able to push out old filament from the top of the
Extruder but with the CB3 this is now no longer an option. So your option is to now to do this operating
from the bottom of the extruder up from the Heat block.
To clean out the extruder properly by removing the nozzle from the heat block. You will need to
disconnect the fan assembly first. To remove this entire piece by unfastening the four bolts connecting it
to the outside of the extruder assembly. Take care of the delicate connections as you slide the Fan case
forward from the Extruder.
You will need to remove the nozzle while the extruder is heated up to 250°C. Now, using both a 7mm
Plus a 20mm wrench (from the provided Nozzle kit box). Use the 20 mm wrench to hold the heat block
and keep it from moving this is located under the red silicon cover. Now with the 7mm wrench (not
provided) start to remove the nozzle itself from the hot heat block. Make sure to use an oven mitt to
protect yourself from burns. Also Please make sure that none of the wires are disconnected While
removing the nozzle. You can unclog the nozzle tip with a pin. Or just simply replacing it with a new one
to save time. It is at this point in time while the Nozzle is off you can use the 2mm Allen Key Wrench to
push up any old filament still left in the extruder tubes.
All new Printer Hotends.
Newer mark 2 Nozzles are now in production, that are available from Craftunique these are designed
to stop any clogging, from happening with longer length nozzles. This comes with a new heat block and
silicon cover to give better temperature control plus a new heatsink with new size screws to hold the
newly designed tungsten Heatbreak. All these do come as standard with our new printers.
If you have the older printers and you find that you have the original hotend assembly and you would
like to change this for a new upgrade parts, then these are available from the Craftunique webshop.
Just remember the new hotends parts, are not compatible with the older hotends. So you will need to
purchase a complete new hotend assembly.
