While printing filament cooling ducts for our E3D Titan Aero toolheads, I noticed that some ducts had consistently poorer print quality on the overhangs of some corners, while others had even performance on all corner overhangs, even when printing with the same printer and filament roll. Keith pointed out that I had switched toolheads between stock and one of our upgraded E3D Titan Aero toolheads with the surround filament cooling ducts. I hadn’t expected the more even cooling to make that much of a difference, but it indeed does.
This beautiful vase was 3D printed in Translucent Turquoise 3mm Chroma Strand Labs Inova-1800 co-polyester filament from Benito Sanducci’s Gosper Fractal Vase design.
Sale? Yes! Turquoise and Turquoise 2 (a darker “emerald” color) Inova-1800 3mm 3D printer filament are a special limited edition on sale for only $39/kg!
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 loose 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.
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!
Following on the success of our toolhead based on the E3D Titan Aero extruder and hotend for the Taz that prints both solid and flexible filaments in either 3mm or 1.75mm, we have updated and released a new version!
- Lighter half height stepper motor increases print accuracy by reducing toolhead mass
- Revised filament cooling duct with outlets on the front, back, left, and right tuned for even surrounding filament cooling
- Updated mount increases stiffness and accessibility
- Compatible with Taz 5 and 6 (and also prior Tazs with a few updates)
