With an improved heat sink and cooling, the LulzBot TAZ Dual Extruder v3 Tool Head is lighter and more compact than its predecessor. This extruder was designed to work with support material, like PVA, which uses water to dissolve and separate from the 3D print. Shipped fully assembled, this extruder doesn't require nozzle leveling or offset calibration when installed.
Note: The Z-axis Toggle Extension and Mount should only be used on a TAZ 6 with the Dual Extruder v3 Tool Head. Leaving this extension on the printer and using it with other tool heads will cause failed probes due to the higher registered minimum position.
