Differences between Lulzbot TAZ models 1 2 3 4 5 6

Postby i-t-w.com » Wed Jan 06, 2016 8:38 am

We get asked this frequently so I figured a post would be helpful.
Feel free to chime in with suggested adds/ changes/ corrections. We start with the features of the TAZ 1, and note changes/upgrades as they happen in later models.

Additional details and many pictures available in the HOLP http://devel.lulzbot.com/HOLP/

TAZ 1-5 have the same bed size and print volume.

TAZ 1:
- Budaschnozzle hotend up to 240C
- Heated bed up to 110C
- PET bed plastic
- 12V 360W power supply with printed endcap
- No LCD or card reader, USB only (LCD cable, housing and panel can be added)
- Printed Y axis end plates, control box, and Lulzbot dual color logo plate
- Toolhead harness has 2 4 pin connectors- 4 pin connector for stepper with multicolored wires, 4 pin connector with 2 red wires for the hotend resistor and 2 orange wires for the hotend thermistor.

TAZ 2:
- Adds LCD with SD card reader for untethered / headless printing
- Mid production- Upgraded to 24V for faster heating, 24V 360W power supply, silver chassis with printed endcap
- acrylic laser etched logo plate
- metal control box
- Survived the fall 2013 flooding of the manufacturing facility!

TAZ 3:
- printed Z nut spring upgraded to a stiffer more durable design
- Metal Y axis endplates with printed bearing and motor mounts. Front and back plate have different arches, are not interchangable, and can't be re-drilled to convert one to another.

TAZ 4:
- Z axis lead screws increased in diameter with different thread pitch- which is why TAZ 3 firmware doesn't work correctly in a TAZ 4)
- Z axis lead screws located by bearings at each end, adding additional bracing to the smooth rods. (TAZ 3 Z rod is only located by the flexible coupler and Z nut)
- Metal X axis endplates
- Larger diameter Z nuts.
- New flexible aluminum Z axis couplers between steppers and Z lead screws
- New control box: Cam lock connectors for all wires entering and leaving. Two extruder connectors on the exterior of the box, making it easier to add a second extruder. Wire exits moved to clear the new lower Z axis motor mounts (a TAZ 3 control box only works with creative modification) LCD Wire harness now externally removable for service
- Different wire harness routing
- Z axis endstop moves from Z motor mount to Z carriage
- Different wire harness routing
- Filament cooling fan (optional on earlier TAZ models).
- 24V 450W power supply, sealed molded plastic
- Toolhead harness adds 2 pin 24V PWM controlled wires for filament cooling fan
- Several Y axis motor mount side endplate holes shift 15mm from Taz 3 endplate positions.
- Y motor bracket changes slightly.
- Bed frame to main frame connectors change to prevent bed lifting and shifting.
- Minor changes to double bearing holder and single bearing holder
- Lighter X carriage with Dual Extruder cable hold down
- Larger diameter Z endstop target bolt (M5 compared to taz 3 M3) and stiffer spring allow for much more accurate Z height keeping and eliminates bed height adjustment keeping difficulty earlier Taz models were prone to

TAZ 5:
- Hexagon all metal hotend up to 300C
- .35mm nozzle in early production, .5mm nozzle in later production
- 3 versions of toolhead connectors through the production run: First: "V2A" 4pin + 4Pin + 2Pin + 2Pin, Second "V2B" 4pin + 4Pin + 3Pin + 2Pin to avoid mixing up the 24V filament cooler fan and 5V micro blower fan connections. Third through the end of production "V2C" 8x2 pin. LulzBot has a handy chart with adaptor part numbers for reference https://www.lulzbot.com/tool-head-adapters
- PEI bed plastic. More durable, lower maintenance (no acetone!!), better adhesion.
- 24V 450W power supply, sealed molded plastic in early production, 500W higher quality metal enclosed power supply in later production.
- Toolhead harness adds 2 wires supplying fixed 5V

https://www.lulzbot.com/store/parts/ext ... arness-add
To the hotend heatsink "microblower" cooling fan
https://www.lulzbot.com/store/parts/micro-blower-55v

TAZ 6:
- Hotend upgraded to "V2.1" which changes the heatsink cooling fan to a front mounted 5v with printed duct, adds a second filament cooler on the left side of the filament for more even cooling, and changes the toolhead carriage design.
- Print volume reduced slightly in X and Y to 11.06"
- "Auto bed leveling" added, which compensates for the print bed being off from parallel with the X carriage and the Y carriage not being perpendicular to the Z axis. Like the LulzBot Mini, the TAZ 6 runs a calibration routine at the start of every print where the print nozzle makes electrical contact with washers at the corners of the bed. The Z height values are fed into the firmware, and the Z axis runs up and down dynamically during the print to compensate. Also new is a "sanity check" during the bed calibration that halts the calibration if a value is outside a reasonable range. This feature automatically halts calibration, wipes the nozzle in a different pattern, then re-starts the calibration.
- Automatic nozzle cleaning wipes the nozzle on a replaceable pad prior to the auto bed level routine to help clean the nozzle and aid in good electrical contact during the bed calibration.
- X axis rods increase in size to 12mm
- all smooth rods and bearings are improved to an upgraded high accuracy system
- Z lead screws changed to a different spec, are now (shiny silver) stainless steel, no lubrication. Z nuts are interchangeable between TAZ 4/5/6
- New expanded metal control box housing consolidates power supply, RAMBo board, LCD Panel w/Control Knob and 1 power switch along with an exhaust fan into a single unit.
- Wiring is simplified and streamlined
- Steppers are all black
- X carriage is moved in between the Z smooth and threaded rods to reduce leverage
- ninjaflex washer is added between the X/Z carriers and Z drive nuts to reduce binding
- Z home is now accomplished with a push button at the left rear of the bed
- Z offset can be adjusted during the print from the LCD
- LCD text interface improved, with larger print in some sub menus and animated graphics for some operations.
- Y front endplate changed to match the Y rear endplate
- Corner brackets upgraded to aluminum
- Frame extrusions upgraded to locking T-Slots
- Travel maximum and minimum endstop switches on all 3 axis (prior TAZs had only minimums)
- Automatic temperature settings generated in Cura, no need to pre-set temperatures
- X maximum and Y maximum endstops added. Y endstops are relocated from the frame to the bed itself. X maximum endstop installed on rear of X carriage right blower fan. Wireing changed to match.
- Change to mounting feet and rod mount on Y bed corners using printed dampers
- Fillament guide path spinner mounts can now fold up against frame with the spinner removed
- https://www.lulzbot.com/cura automatically controls temperature through the entire print process.

Upgrading a prior TAZ to a TAZ 6 has a number of dependencies that limit piecemeal upgrades. The mechanical parts you'll need are:
- 12mm x rods
- 12mm bearings
- control box
- aluminum bed plate
- Y front endplate (same as TAZ 4/5 motor end plate)
- extruder heatsink cooler fan
- filament cooler fan
- a pile of heat inserts
- switches
- wire, pins, and connectors for the required re-wire
You'll need to print a bunch of parts as well. We sell many of them, and are working on a kit of parts based on some pre-production chassis from LulzBot

Upgrading a TAZ 4 to a TAZ 5 is covered in another thread, but to recap:
- Replace PET bed plastic with PEI Replace PET with PEI on the bed https://www.lulzbot.com/store/parts/lul ... -pei-sheet
- Upgrade the toolhead to the V2 hexagon
https://ohai.lulzbot.com/project/taz4-hexagon-toolhead/
https://www.lulzbot.com/store/tool-head ... ol-head-v2
with requires adding wires to the extruder harness
https://www.lulzbot.com/store/parts/int ... arness-add
https://www.lulzbot.com/store/parts/ext ... arness-add
- Flash the firmware to TAZ 5

Upgrading a TAZ 3 to TAZ 4/5 is far more involved.
If your want "Cool project, time and money aren't really an object, I like hunting down obscure parts and printing my own upgrade parts" go ahead with a TAZ 3 to 4/5 upgrade
If you want a "TAZ 4/5", just buy one ready to go. You'll likely be money ahead (control box connectors are around $30 ea, for example), and will save a bunch of time.
- Perform the upgrades in Taz 4 to TAZ 5 above as needed.
- Upgrade the Z axis, which entails the first several points of the TAZ 4 upgrade list and is quite a bit of work and expense to do "correctly", as it involved changing the wiring harness.
- Flash Firmware
- Upgrade the power supply. Not required, but the printer heats much more quickly.
- Add a filament cooling fan and wiring:

<shameless plug> We also sell many of the necessary parts that are hard to source elsewhere https://itworks3d.com

Thanks to all that that helped with this!

TAZ 5:
Mid production switched to single 8x2 pin connector (V2c).


I've searched through the BOMs and cannot find any information about this connector and pins.
I'm upgrading the Extruder and would rather not have to do any splicing.
Do you have any links for these parts?




Best regards,
PCH

The pins are the same, so you can (carefully) remove them from the one type of connector housing and place them into another.
Here's a handy reference https://www.lulzbot.com/tool-head-adapters

I will express my CRAZY ideas at any time! So you have been warned. None of my opinions are Lulzbots and can be wrong at any second.

You're welcome

One typo on my section, I apperently had these in there twice
- Bed frame to main frame connectors change to prevent bed lifting and shifting.
