Frequently Asked Questions - TAZ Pro S LulzBot

What types of filament can the TAZ Pro S print?

The TAZ Pro S supports a wide range of filaments including PLA, ABS, PETG, Nylon, Polycarbonate, TPU, and composite materials like carbon fiber-filled filaments. Its all-metal hotend reaches 300°C, allowing high-temperature materials.

How do I level the bed on the TAZ Pro S?

The printer features automatic bed leveling using a capacitive sensor. Simply run the auto-leveling routine from the menu, and the printer will map the bed surface and adjust the Z offset automatically.

Can I print with two colors or materials simultaneously?

Yes, the TAZ Pro S has a dual extrusion system with two independent extruders. You can print with two colors or different materials, such as a dissolvable support material. Use the appropriate slicing profile in Cura.

What is the maximum print speed?

The maximum recommended print speed is 200 mm/s. However, optimal quality is achieved at 50-80 mm/s depending on the filament and layer height.

How do I change the nozzle?

Heat the extruder to 220°C, then carefully unscrew the old nozzle with a wrench while holding the heater block. Install the new nozzle and tighten it. Allow cooling before use. Always use genuine E3D nozzles.

What software is recommended for slicing?

LulzBot recommends Cura LulzBot Edition, which includes pre-configured profiles for the TAZ Pro S. You can also use other slicers like PrusaSlicer or Simplify3D with custom profiles.

How do I clean the print bed?

For the PEI sheet, clean with isopropyl alcohol & a lint-free cloth. For the glass bed, use warm soapy water or a dedicated 3D bed cleaner. Avoid acetone on PEI.

What should I do if the filament jams?

First, heat the hotend to the filament's melt temperature. Then manually push filament through or use the 'load filament' feature. If jam persists, remove the nozzle and clean the heat sink. Consider using a hardened nozzle for abrasive filaments.

Is the printer enclosed?

Yes, the TAZ Pro S has a fully enclosed build chamber with a polycarbonate door and panels. This helps maintain stable temperatures for materials like ABS and reduces warping.

Where can I find spare parts?

Spare parts are available from LulzBot's official store or authorized distributors. The open-source design means many parts (like hotend components, belts, and bearings) are standard and can be sourced from third parties.

5.7 Feed the included sample coil of 1.75mm PLA filament into and through the bottom of the LulzBot Green filament sensor marked 1.

5.8 The rear black filament sensor marked 2, is only used with the TAZ Pro Dual Extruder option.

Note that Sensor 1 is used when your TAZ Pro S is equipped with a single extrusion tool head. Filament sensors 1 and 2 correspond to Extruder 1 and Extruder 2 on Dual Head equipped models of the TAZ Pro. Each filament sensor must go to the correct extruder in order for your TAZ Pro S to function properly.

5.9 Locate the filament tension knob and filament feed path where the loaded filament was removed during step 5.4. Filament feeds down this path and into the hot end for printing.

STEP 2:

Turn Counterclockwise:

• 1 to 2 full turns for PLA, ABS, and other hard filament.
• 3 to 4 full turns for NinjaFlex, Nylon, and other flexible filament.

!

Do not force the filament tension knob tight. Using excessive force will damage the laser sintered nylon that holds the metal insert in place.

i

Having the idler tension too loose or too tight will cause issues with print quality and potentially cause jamming in the extruder.

5.9 Push the filament by hand completely through the feed tube until it exits near the filament guide tube holder on the top of the extruder. Straighten the filament slightly and place your thumb on the filament tension knob and pull the lever away from the filament feed path. Feed the included sample coil of 1.75mm PLA filament into the extruder.

The filament must be inserted into the dual hob gears for filament to extrude properly. If it is difficult to feed filament into the filament feed path, trimming the filament at a 45^ angle may help.

After removing filament, a small residual amount remains in the hot end that needs to be cleared out through the process of purging as detailed above. This purging process helps to remove any residual material left in the hot end.

Starting Your First Prints

If you need to make changes to your model, use the Prepare sidebar at the top left corner of Cura. Once changes are made, Cura will automatically begin implementing the changes, also known as re-slicing.

The X-Axis gantry may shift after your 3D printer is powered off. Every time the LulzBot TAZ Pro S powers on, it will attempt to auto-home. Verify that the X-axis and print bed are clear before turning your machine on. Failure to do so could result in damage to the printer or other equipment.

Your LulzBot TAZ Pro S can be operated without a USB tether to a computer by using the touchscreen LCD and included flash drive. Once models are sliced and a .gcode file is saved they may also be saved to the included flash drive by clicking Save to File in the lower right corner of Cura. Once saved, models may be printed directly from the flash drive by plugging it into the slot located on the top of the touchscreen LCD, pressing the USB Drive button, and selecting the model you would like to print.

b.1 Your 3D printer is now ready to print! Click on the Monitor button at the top of the main Cura interface. This will change the sidebar on the right side of the screen to show printer information and controls.

Before starting a print, check that your printer is ready. The hot end is still hot, use caution:

• Confirm that all packaging has been removed from your LulzBot TAZ Pro S
• Verify that the 3D printer is in a well-ventilated area, on a flat and level surface, and has 30cm (12in) clearance in all directions.

b.b Once the hot end reaches its wiping temperature, the tool head will move to the wiper pad, cleaning the nozzle of residual filament. After the nozzle has been cleaned, your LulzBot TAZ Pro S will heat to probing temperature and conduct an automated self-leveling sequence by touching each of the four bed corners. When the leveling process is complete, the printing process will commence.

If probing fails to detect one of the bed corners, the printer will attempt self-cleaning again, then repeat probing. If this fails three times, or if the bed corner is visibly pushed down during probing, the printer requires manual nozzle cleaning. (Refer to the Maintenance section at the end of this guide for details on nozzle cleaning.)

DO NOT use metal to clean the nozzle.

7 Maintenance and Care

There is a small length of PLA filament remaining in the hot end after your first sample print. You can remove the remaining filament by following the steps in Section 5.4. Use this process whenever changing the filament to ensure a clean switch between different filaments and to avoid extrusion issues due to print temperature differences.

When using a filament other than PLA for future prints, there may be a difference in the temperature required for purging the residual filament in the hot end and printing with the new filament. When changing filament, choose a temperature that splits the difference between the two required printing temperatures. The chart on the next page lists printing temperatures for some of the most popular filament available for your LulzBot TAZ Pro S.

Maintaining Your LulzBot TAZ Pro S Desktop 3D Printer

Make sure that the hot end and print bed are at room temperature before beginning any cleaning or maintenance unless otherwise noted.

Print Bed

Adhesion to your LulzBot TAZ Pro S modular heated print bed is the foundation of a great 3D print.

The bed can be used in three supported configurations: PEI, PEI with glue stick, or plain glass. Your LulzBot TAZ Pro S ships with the PEI surface facing up since it's the most commonly used print surface. Refer to the chart at the beginning of Section 7 of this guide for bed preparation for specific materials.

Following these tips will help you get the most out of your print bed:

PEI: Oil on your skin and accumulated dust can negatively affect print adhesion to PEI. For optimal performance, lightly wipe the print bed and corner washers with a dry lint free cloth between prints. To deep clean the PEI print surface and corner washers, wipe with diluted Isopropyl Alcohol (1:10 IPA to water ratio) and a clean lint free cloth.

Always wait for the PEI print surface to cool to removal temperature before attempting to remove 3D printed objects. Treated appropriately, PEI is extremely durable, but note that even well-treated PEI will not last forever. It will need to be replaced periodically and is considered a consumable item. Replacement Glass/PEI Print Surfaces can be purchased at LulzBot.com

Bare Glass: The ability to print on bare glass is especially useful for TPU filament like Ninjaflex. To use the glass surface, unscrew each corner washer holding the print bed in place with the supplied 2mm hex key, then flip the print surface and place it back on the heater bed with the glass side up. Screw in each corner washer to hold the bed in place. Using care not to over-tighten, make sure that the washers are flat and parallel with the surface of the glass. If you do not wish to use the bare glass surface when printing with TPU filament, it is highly recommended to use a PVA glue stick on the PEI surface.

PEI with Glue Stick: For some filament types, a polyvinyl alcohol (PVA) glue stick, such as Elmer's® brand glue stick, is necessary for bed adhesion and/or part release. Apply the glue stick in light, even coats.

Periodically remove accumulated glue with a damp paper towel to maintain a flat, smooth base for your 3D prints.

Electronics Box Cleaning: ⚠ Unplug the power cord and USB cable before beginning any maintenance on the LulzBot TAZ Pro S control box.

Remove filament from the filament holder and unscrew the ten screws holding the control box panel in place. Then remove the panel to gain access to the control box. Using compressed air, clear the fans, power supply, and area around the control board of any dust or debris that may have collected inside.

Nozzle Wiping Pad: A clean nozzle tip is critical for the performance of your LulzBot TAZ Pro S. Ensuring metal-to-metal contact in the leveling sequence is critical. If you are experiencing leveling failures or have noticed prints starting too close to the bed, your nozzle wiping pad may require attention.

▲ Never use metal to clean your nozzle.

The wiping pad is reversible and replaceable. To remove a pad, pry up on it with the dental pick or tweezers from the supplied LulzBot TAZ tool kit. Then, either flip the pad over (if the other side is unused) or replace the pad with one of the spares included in the tool kit. Wiper Pads need to be replaced periodically and are considered a consumable item. Additional pads can be purchased at LulzBot.com

Smooth Rod Cleaning: Wipe down the smooth rods on the X, Y, and Z axes using a clean, dry lint free cloth. The bushings that allow movement along the smooth rods are self-lubricating.

▲ Never apply lubricant to the smooth rods.

WARNING - Electric shock can kill.

ALWAYS disconnect the printer by unplugging the power cord before attempting to enter the electronics box enclosure.

Failure to follow warnings could result in personal injury, death, or property damage.

Print Area Cleaning: With regular use, dust and debris can collect underneath the printer and may cause interference with the Y-axis motion. Periodically clean and dust the area underneath and surrounding the printer to prevent this. Make sure that the hot end and print bed are at room temperature before beginning any cleaning or maintenance unless otherwise noted.

Maintaining Your LulzBot TAZ Pro S Desktop 3D Printer

HOT SURFACE BURN HAZARD. CONTACT MAY CAUSE BURN. DO NOT TOUCH THE HOT END.

The hot end on the extruder can quickly heat up beyond 180°C (356°F) and can burn your skin if you touch it.

Tool Head Cleaning: While the dual drive gears of the M175 extruder usually remain clean, you should inspect the drive gears from time to time by turning the filament tension knob all the out (counterclockwise) and removing it from the quick release lever. The quick release lever will open, exposing the dual drive hob gears. Use compressed air to clear any residual filament from the tool head and reassemble. Reset the tool head tension as described in Section 5 of this Quick Start Guide after reassembly.

Check all fans on the tool head to ensure that they are functioning properly during printing. Note that the extrusion cooling fan on the front of the tool head may not turn on while printing the first few layers on the print bed depending on the filament used. While the printer is off, blow out all fans with compressed air to clear any build up of dust or debris.

The nozzle and heater block are coated to reduce the accumulation of filament. However, if you notice an accumulation of filament on the nozzle and heater block, it can be cleaned by heating the hot end up to 205°C (401°F) and then carefully wiping the affected areas using the maroon Scotch-Brite ^™ scrubbing pad from your TAZ Pro S tool kit.

Do not use metal to clean the nozzle on your tool head. Metal will short the self leveling function and can blow an internal fuse or damage your printer.
