 The official word on clearing jams / clogs, which helped the FIRST time it jammed, but not the second:
-:: So if you have done cold pulls on a normal extruder its the same concept for the flexystruder. Heat up the tool head to printing temp. (well say 230) Then manually extrude some filament through the hotend by manually turning the large gear on the toolhead counter clockwise. Once you get a little string of filament coming out drop the temp of the toolhead by 100 degrees wile slowly extruding a little more filament. Then once the tool head gets to the lower temp (say 130) manually retract the filament by rotating the large gear clockwise while pulling up on the filament with your hand. Try this 4-5 times and see what happens. Let us know if it works.

Ninjaflex!

New page

As of 2017.02.10 the Lulzbot Mini has been repaired and has a brand new extruder head. This extruder head uses '''NinjaFlex (TM) rubber filament only!'''

Cura users:

1. Download the newest version of the Lulzbot Edition of Cura from https://www.lulzbot.com/cura
2. Install and start Cura
3. From the menus: '''Machine''' -> '''Add New machine''' -> '''Lulzbot Mini'''
4. From the menus: '''Machine''' -> '''Machine Settings'''
5. '''Change Tool Head''' -> '''Flexystruder v2'''
6. '''E-steps per 1mm filament''' -> '''918'''
7. '''OK'''
8. For your print material, choose '''NinjaFlex'''

The recommendation is '''220 C''' for the melting temperature of the material, and it is currently advisable to lay down some glue.

			== About that ... ==

			On 2020.01.20 once again, I attempted the afore-mentioned '''cold pull''' with more success: I attribute the success to using slightly more force and a lot less speed (and a lot more patience) when manually rotating the large gear in either direction.
