Overview
The Lulzbot TAZ printer is a commercial 3D printer put together and sold by the people at Lulzbot.
It is designed using a metal-based frame with custom 3d-printed parts for corner-couplings and extruder-sections as well as controller-casing.
We had one donated to us by Lulzbot on the 28th of October through Aeva, a Lulzbot representative who was looking for a good home for one that was used as a demonstration-unit at (at least) the BlenderConference the weekend before.
Techninc ended up being the lucky recipient of the unit and Aeva and Chris came by to help set up and test the unit, as well as provide assistance and technical guidance on using the machine.
Specifics
The machine is based on a regular XYZ-oriented setup; much like the Prusa i3. A pair of motors actuate the Z-height spindles, guiding the X-arm up along a set of guiding-rails. The Y-movement is realized by moving the heated printing-bed across a set of guiding-rails.
The X-arm has an extruder-unit referred to as the 'Budaschnozzle 2.0' with a 0.35mm nozzle fitted.
ABS PRINTING READY
The bed and extruder are, as delivered, suitable for ABS-printing only. The bed is coated with a special plastic; the extruder lacks a fan.
PLA PRINTING: NEEDED
For printing with PLA, one would need to fit a fan-unit on the side of the extruder-head (please find the two suppled screw-holes there) that would blow air across the cool-ribs and the printed object but would *NOT* blow across the metal of the nozzle.
Also, the bed-surface should be adjusted , as well as heater-temp and extruder-temperature settings.
As of 2013-11-17, the Lulzbot has been modified to be able to use PLA as stock-material as well. It has been fitted with a fan-duct mounted on the side by two M3 hex-key bolts. The supplied 40x40mm fan seems a bit low-powered and should perhaps be replaced with a stronger version in the future.
Wiring has been made to run through the proper cable conduit and has been made so that the fan can be easily replaced by means of a male/female connector on the top of the extruder-carriage.

Printing
Preparing a design for printing
- Info about STL, requirements , Slic3r and filament *
Preparing the printer for printing
When you've finished using Slic3r and have prepared a G-code file for use with the printer; please make sure that the G-code was for the right model printer, as well as the right type of filament loaded in the printer.
Currently, the actual printing process is performed and monitored by PronterFace. Please find it in the '3d printing tools' tab at the top of the desktop. A future arrangement might instead use OctoPrint. Procedures for either should be greatly the same.
=== Connecting to the printer
- Make sure that the printer is on and connected (both PSU-brick and control-unit). Also to USB.
- Start the printing-software (PronterFace)
- The printer will be either on /dev/ttyACM0 or /dev/ttyACM1
- When pressing 'connect', the Lulzbot will report it's identity if the right port is selected in the side-bar on the right.
If you can move the head around with the interface provided on the left, you are connected to the right printer.
Pre-print routine
- Set the 'bed' and 'extruder' temperatures according to the material you are going to print with and use the 'SET' buttons on the right of the selections to turn the heaters on. This will pre-warm the printer for use.
- If you change your mind and decide to NOT print , DO NOT FORGET TO TURN HEATERS OFF
