Hello and thank you for choosing the Creatr Dual for your printing needs.
The following solution will instruct you on how to unclog your Leapfrog Creatr Dual 3D printer hot ends.
Please keep in mind that due to the high temperature of the extruders direct contact between the surface of the extruders and skin may cause burns.
For the steps that you will need to take in order to unclog your CreatrHS extruders you will have to have at your disposal the following:
a pair of pliers;
a number 8 pipe wrench or ratchet wrench;
- a number 2 and number 1.5 Allen key;
- a needle.
Connect to Simplify 3D or Repetier Host
Now connect the printer to the Simplify3D / Repetier Host software on your computer and set the extruders to heat up to around 230-240 degrees Celcius. Wait for the temperature to stabilize and then use the retract command from Simplify3D to try and remove the filament.
Can`t remove filament with retract command?
If you do not manage to remove the filament this way your other option is as follows:
Remove the nozzles
First you have to remove the nozzle from the extruder that is clogged you do this by using the pliers to hold the extruder in place and use the number 8 wrench to remove the nozzle as shown in the picture below Pic.1.
Pull out the extruder
The next step is to pull out the extruder you do this by loosening the grub screw with the number 2 Allen key from hegind the front fan as shown in Pic.2 and then gently remove the extruder.
Heat up the extruder and use the 1.5 Allen key to unclogg the extruder
After pulling out the extruder, heat it up to 240 degrees Celsius and using the pliers to hold onto the extruder so as not to have direct contact between the surface of the extruder and your skin use the number 1.5 Allen key to push through the extruder until the filament that was stuck comes out as you can see in the picture below Pic.3
Depending on how the filament broke you can try to remove it by introducing the number 1.5 Allen key from either side of the extruder.
Let the extruder cool off
Once the extruder is unclogged you can let it cool down before you mount in back up in the carriage. Also at this point make sure to check the nozzle for residue and use a needle to check and see if the vent is clear .
Adjusting the extruders height
After mounting the extruder back into place please read the following instructions from the links below to adjust the extruder height and recalibrate the bed.
