LulzBot TAZ User Manual

Advanced Usage
7.1 Intro
After becoming familiar with printing with the TAZ 3D printer with the
default settings there are a few advanced techniques that may help in getting
better and more consistent prints. Some of these instructions include items
and materials not included with the TAZ. With any of these additional
items or materials, follow safety and usage guidelines as instructed by the
manufacturer.
7.2 Changing nozzles
The TAZ 3D printer ships with a standard 0.35mm nozzle which allows
small layer resolution and up to 0.35mm layers. Although the 0.35mm
nozzle will be perfect for most printing applications LulzBot also offers
smaller and larger nozzle sizes.
If you have already printed with your Budaschnozzle you will need to
loosen the nozzle after the hot end has reached 160C. Unless heated past
160
◦
C , any ABS/PLA on the threads will influence how easily the items can
be moved. Removing the nozzle with the hot end cold, with the presence of
plastic on the threads can potentially damage the nozzle threads/threaded
extension
When re-installing the nozzle, slightly thread the nozzle onto the threaded
extension, only one thread then set the hot end temperature to 160C. Once
the hot end has reached 160C finish installing the nozzle. Take extreme
caution when handling the hot end when at high temperatures; when at
160C the hot end can cause severe burns. Use a pair of pliers or thick leather
gloves when handling the hot end when at extrusion/melt temperatures. If
your hot end has not been used the nozzle can be removed with the hot end
at room temperature.
To change the nozzle you will need an 18mm and 13mm wrench. Slide
the 18mm wrench onto the rectangular aluminum heater block away from
the heater resistor and thermistor wires.
Using the 13mm wrench turn the nozzle counter clock-wise. Make sure
the nozzle is turning off of the threaded aluminum extension that runs up
through the heater block. Do not allow the heater block to turn. This can
put strain on and possibly damage the wiring.
