Apply grease to the linear bars of the Y axis as well, then spread the lubricant around with your fingers to form a
thin layer on the shaft.
»
Plug in and power up the printer and move the build plate to the lowest point (go to Axes menu, and press the Z
down arrow until the bed reaches the lowest point).

Turn the Craftbot printer off and unplug it from the electrical outlet.
7.3. Removing clogs from the extruder
The number one inconvenience you will run across when 3D printing is clogging of the extruder. But we have good
news for you! This problem can be easily avoided by following a few simple rules of “3D printing etiquette”.
• First, always wait until the extruder is fully heated to its intended temperature before inserting the filament.
Inserting the filament at a lower temperature is just asking for a clog .
»
Heat up the extruder and then secure the screw on the top of the extruder. Now you can move the filament
smoothly. After the process don’t forget to loosen this screw again!
• When unloading or changing the filament:
»
Always heat up the extruder completely first.
»
Then press “Extrude” for 5 seconds and then immediately press “Reverse”, helping filament retrieval by pulling a
little bit with your fingers on the filament end coming out of the extruder.
»
The “Extrude” operation is necessary because the hotend needs to melt the whole previously melted filament.
• If the extruder is clogged, you will need to clean its passageway.
»
You can use one of the small hex wrenches that came with the Craftbot.
»
To do so, heat up the extruder to 250°C.
◊ While the extruder is empty, push any excess filament out by plunging the hex wrench down into the passageway:
• Make sure to do this with sufficient force but not violently to avoid damaging the machine, and always take
precautions because the extruder is very hot.
• It is especially important to purge any leftover filament before using a different filament as the different filament’s
properties (even the same material in a different color) can cause clogs from inconsistencies. For example: you
must heat up to 250°C to clear out any extra ABS before using PLA.
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 all occurrences. If you still cannot clear the passage with just this method, you
may want to move on to the next method by following these next steps to actually remove the nozzle itself…
