Taz Workhorse with new Meteor 285 not extruding and making clicking sounds when trying to purge

I’ve just upgraded my workhorse with a new Meteor 285 and I did a test print with it but it stopped extruding in between the print and started making clicking noises because I think the extruding gear is skipping. I’m not able to push in new filament too because the filament is stuck. The ratchet adjustment stick is stuck too.

Okay I had a similar problem & @McLeach looked at it & lulzbot & the retraction is too high so clear the chamber to 1/2 mm / sec

I’m a bit of a beginner. Could you tell me what to do to clear out the stuck filament?

Yes sir it’s under settings in lulzbot cura
It’s ether speed or distance however to unjam it you might need to open it to unclog it in certain cases

Anyone else with other ideas go ahead

I could open it up but is there any guide on it. I saw the assembly instructions for the Meteor 285 but it starts with the extruder gear part already assembled

A clog on a lulzbot can be done with a purge there is a cold purge & a hot force purge then their are tools to unclog

But a hot purge just results it in making clicking sounds and that’s it.

Sounds like a total jam your going to need a technician or engineer

I have some experience with these tool heads as I have two of them. The issue I have found is that with PLA you will eventually get heat creep and it will jam the extruder. After talking with Slice and Bondtech the issue appears to be in the way it’s assembled. There appear to be some differences between how Slice documents the assembly vs how it’s done at Lulzbot in the OHAI.

Slice has you using thermal grease between the heatbreak and the ACE coldblock. See here, scroll down until you see the part where they prepare the heatbreak. These are the instructions for the Magnum+ but the portion that has to do with the heatbreak is the same for all 2.85 mosquitos.

This differs from the OHAI:

In the OHAI, you are not using any thermal paste. This lessens the ability of the heatbreak to move heat away to the coldblock, resulting in what you are likely experiencing.

This is really only a problem with PLA I believe. Lulzbot as a company is more geared towards products that print ABS and such so I don’t think they are doing it wrong, per se. But certainly dfferently.

You are looking at a total disassemby of that tool head and getting some MX-4 thermal paste. After I did this to my two Meteor 2.85 tool heads, I never had the clicking of death again.

Through our support ticket, it was determined that the 5v fan connector inside of the control box was no longer connected causing heat creep and clogging.
