I recently was given a used LulzBot Taz 6. It appears that the hot on it is going out or is worn out. I can get 1 or 2 prints to print but then it clogs. Looking to replace the entire hot end and hopefully remove the issue. I have been 3d printing for 6 years, but i have never used a LulzBot machine. What options are out there for this machine? looking for a drop in solution and any help would be appreciated. I would like to have a hardened steal nozzle to print material up to 300 degrees
The stock hotend for a Taz6 was never designed for PLA, and PLA is not a good match for 2.85mm anyway, so if that’s what’s jamming, a new stock hotend is not going to help.
I would start with a CHT-clone nozzle. They’re dirt cheap, and the faster melting is going to help reduce the pushing force required by the outdated hobbed bolt that drives a stock extruder.
Options are entirely up to your budget, since they’re completely open-source machines and can be modified to use whatever you want.
My current V6 hotend for 2.85mm is the orbiter, 5015 blower for part cooling and a 3010 blower for the heatbreak fan. It’s rigged for BLTouch and the Biqu Hermit Crab quick toolchange system, so it’d be a bit of adjustment for trying to use with a stock setup.
Hey Wrathernaut, thank you for reply.
I am printing in PLA.
You mentioned that the hotend was not designed for PLA, in your opinion:
Would I have better results using a different material, PETG or ABS
or is there a better hotend suited for PLA thats is bit more modern?
If your goal is printing PLA, do 1.75mm. Cheap option for that upgrade is a Biqu H2. Check this printables listing for details on how to do that.
ABS? 2.85mm is fine and works well with the stock hotend. It’s what it was designed to work with. PETG works well too, but PETG is a little more “oozy” and stringing may be an issue.
But for the cost, definitely give some cheap hardened-steel CHT-clone nozzles a try. I bought mine from aliexpress and have been happy with them.

Thank you for your insight. I really appreciate your time. I saw that lulzbot has a 1.77 mm hot end. The M175 v2 Tool Head ,1.75 mm, Single Extruder, 0.5 mm.
Unless you are comfortable with doing your own hardware and firmware, using one of the tool heads that are available from LulzBot is probably a better option. The M175 V2 tool head is an excellent choice, IMO.

The M175 is great, but for the cost of it? I’d just buy a Bambu A1. The Taz 6 is great if you embrace the open-source nature and build and modify it to suit your needs, but if you just need a printer? It’s nearing a decade old and it was pretty good then, but is just outclassed now.
Well since you never Lulzbot I would recommend maintaining like washing the bed with one layer of soap then a layer of water & dry it off
(For magnetic beds)
Importantly be sure to clear the chamber of the extruder if your using PLA set the extrusion to 245•c & only for up to 15 minutes or less then just pull out filament then flush this is where you flush the extrusion chamber but instead of a hex wrench i recommend this tool
