Lulzbot (FDM):

It would really benefit from someone dismantling the hot head, cleaning
it thoroughly and assessing if we need to repair/replace/update the
whole thing or the nozzle or something else.
Similarly, it has mounting holes for a plastic enclosure to improve
temperature regulation of the print area. Is this something we need? [5]
With budget around £200 I'd be inclined more towards getting a whole other printer
than trying to fix improve the one we have.
I've got an Elegoo Neptune 4. One of them with an enclosure¹ is £205.98.

It's considerably faster than the lulzbot in the space and I've only had 1 failed
print where I'd set the z-offset too high (over compensated for elephant footing) and
first layer didn't stick to the bed (can't really blame the printer for that).
I've got a benchy from it sitting on my desk that I can drop in past the space this
evening if anyone wants to have a look at quality. Or I'm happy to lend mine to the
space for a bit if we want to try it before getting one. It uses 1.75mm filament so
wouldn't be able to use the pile of 2.something mm that we have (but that's maybe
not a bad thing). It's supported out of the box in recent cura releases if anyone
wants to have a play at slicing things to get an idea of print times.
I haven't really looked at what other options there are since I bought mine (July
2023) so something else might be a better option now. If budget stretches to it one of
the core-XY printers would be another step up in quality + speed.
I'd be happy to have a look at the lulzbot to see if it can be fixed/improved, but
it'll be at least a couple of weeks (maybe a couple of months...) before I'd have
time for that if anyone else can have a poke at it sooner.

¹ I don't have an enclosure and haven't had any issues, but I've stuck to PLA
rather than the more temperamental filaments and the hackspace might have more annoying
drafts than my flat.
