Hello and thank you for choosing the Leapfrog Xeed for your printing needs.
The following solution will instruct you on what to check when you notice the filament curled in the print head and clogged up the extruders.
1. The first step to do before starting to check the print head is to make sure you remove any filament residue from the print head. Please follow the link below and see how to open up the print head:
2. The next step is to make sure the pressure on the filament is not to much and the filament is snagging in the drive units in the drawer and the ones in the print head. You can adjust it using the steel ring on the drive units;
3. Once the pressure is adjusted and there is no more filament residue try to print the model again.
If the same problem is present, the next step is to turn on the printer and see if the two fans underneath the drive units turn on and then turn on the other two using the LilyPrint interface:
