To keep your LulzBot Mini and Taz performing at their best, it’s important to check for wear and loose parts periodically.
A few items you can check quickly and easily:
Loose bed mount screws
If you can spin any of the washers that hold down the corners of the bed on the TAZ 6 and Mini, they are too loose. Snug them up with a 2mm hex wrench
No “hulk hands” here though, be careful not to strip out the hole.
Play in the bed plate
Try to wiggle the bed in all directions checking for excessive play that may be caused by loose screws or worn bearings.
If you find more play than you’d expect, it may just be loose screws that secure the bed plate to the double bearing holders. Using a 2mm hex wrench, remove the screws that secure the heat bed washers. Being careful not to lose the screws washers, or spacers below the washers, remove the screws and washers, lift up the heat bed and set it off to the side, and check that the screws underneath the heat bed that secure the bed plate are all snug.
Check play again. If you’ve taken out the play, great! If not, it’s probably time to replace the bearings under the bed plate in the double bearing holders
Play in the X carriage
Wiggle the tool head in all directions to check for excessive play that may be caused by loose screws or worn bearings.
Culprits for play include looseness in the screw/s that secure the toolhead to the X carriage
Loose screws that secure the extruder and hotend to the toolhead mount, cracks in the extruder body and toolhead mount, and worn bearings in the X carriage and x carriage upper bearing holder.
Squeaky smooth rods
Wipe down the smooth rods with a lint free cloth to remove dust and residue. This will often remedy squeaks when the carriages are moving.
If you need to replace worn bearings, the old bearings need to be pressed out, and new bearings pressed in, which can be a bit of a challenge without the right tools.
We have factory made parts for the 1.03 “Foxglove” Mini that include the bearings and heat inserts already installed, so you can conveniently replace the entire bearings housing assembly instead!
Here are the parts that contain the bearings that you may want to replace:
Print solid AND flexible filaments on your LulzBot® Mini 3D printer, without changing toolheads!
Available in your choice of either 3mm or 1.75mm filament.
Check out the E3D Titan Aero at work
IT-Works 3D’s new toolhead based on the E3D Titan Aero extruder is compatible with all LulzBot® Minis and joins our successful and well regarded E3D Titan Aero tool head for TAZ 5 and 6 offering you convenience, performance, and greater filament options.
Prevent burned fingers!
A custom molded silicone boot surrounds the heater block, preventing accidental burns, and keeps stray filament from melting to the heater block, making cleanup of stray filament easy.
Abrasive filaments? Sure!
We can customize our E3D Titan Aero toolheads for you to better withstand the wear from abrasive filled PLA filaments like stainless steel PLA, carbon fiber PLA, and iron PLA.
E3D Hardened Steel HOB GEAR
E3D Titanium Heat Break tube (currently only available in 1.75mm)
Micro Swiss Wear resistant Coated Stainless heat break for E3D V6
Micro Swiss Wear resistant Coated Brass Nozzle for E3D V6 is a great balance of performance, price, and upgraded abrasion resistance
Micro Swiss Hardened A2 Steel Nozzle E3D V6 for maximum durability
E3D V6 Extra Hardened Steel Nozzle for maximum durability
Nozzle sizes vary by option, be sure to check them all for the size you’re looking for! Brass and copper nozzles tend to perform better than steel due to their better conductivity.
How do toolhead upgrades work?
– Purchase the optional parts you want
– In order notes, request that the upgraded parts be installed.
– We install the upgraded parts (we keep the stock parts) and ship you the toolhead tested and ready to print!
Upgrades usually take 1-2 working days
IT-Works 3D began building all E3D toolheads with upgraded BOCA sealed bearings starting Oct 2017 to improve bearing durability
Upgrade your E3D Titan Aero and V6 1.75mm hotends for maximum wear resistance and durability with a new E3D V6 Titanium heat break! E3D makes it easy to customize your extruder and hotend to your needs with their modular system. You can achieve high wear resistance in your filament path with the:
Hob: E3D hardened steel V6 hob
Heat Break: Improved wear Micro Swiss Wear Resistant Coated E3D V6 Heat Break Maximum wear resistance E3D V6 Titanium heat break
For the best combination of performance and wear resistance- Micro Swiss Wear Resistant Coated E3D V6 Nozzles
For Maximum wear resistance E3D V6 hardened steel nozzle and Micro Swiss E3D V6 Hardened A2 Steel Nozzles
www.itworks3d.com will be releasing the E3D Titan Aero toolheads for LulzBot Mini very soon!
The E3D Titan Aero allows you to print both solid and flexible filaments without changing toolheads.
Upgrade to hardened parts, and you can also print abrasive filaments like Proto Pasta Carbon Fiber PLA
