Video Guides

IMPORTANT NOTICE:
*************************************************************************************************
There is a miss on this video guide that will be corrected soon. To use the Direct Drive Interface Plugs with Slice Engineering hotends it is recommended to use a PTFE tube between the extruder and the heat break. Info on how to install it will be posted as a new video. This information does not have an impact on using the LGX FF For Flexibles Set. Below is some useful additional information:

PFTE tube lengths:
Old Mosquito/Mosquito Magnum: 10 mm
New Mosquito/Mosquito Magnum: 11 mm
Copperhead screw mount: 30 mm
PTFE tube should be cut straight on both ends.
Slight chamfer inside is recommended, but not mandatory.
