Hello, I was wondering if I could get some tips and feedback on this print? Some info:

• Flashforge A5M w/ DIY enclosure
• default 0.4mm nozzle
• ELEGOO plain PETG from amazon

Looks ok, but might need some work on overhang cooling + err whatever is happening at the front.

okie dokie, and yeah the hull is really weird, especially with how the layers look so different between the 2 sides

[radiant stone]

The hull is like either the extruder tensioner is loose (but only for that bit), it's too warm (what temps) or something else 🤔

[cursive elm]

maybe uneven ambient temps bc the enclosure door is cracked open

[radiant stone]

🤔 maybe, usually that would also warp the print though...

Actaully you can probably check the spool and see if it spins freely all the way down to the nozzle too...

[cursive elm]

wdym?

[radiant stone]

So if you grab the filament above the printhead area and give it gentle tug, does it unspool easily.

Sometimes it gets tangled or stuck.

[cursive elm]

oh i see

by the way if you were asking earlier, i printed at like 250C iirc

this particular filament might just be total dogshit

[radiant stone]

Elegoo should be a decent brand + i've seen it print fine... 🤔

To try:

• temp tower (and watch the printer screen to see if it actually changes) 225 - 250
• check if you have a ptfe lined hotend or not. (White tube all the way down to the nozzle) In which case you are temp limited to 225 for safety reasons.
• coldpull to clean out clogs.

Leave you to it 🙂

ok so update, a few weeks ago i ordered some replacement parts including a nozzle, so i decided to swap that out, and the hull artifacts are pretty much entirely gone

at this point i'm wondering if i either damaged the original nozzle during maintenance (there were times that i handled it roughly), or if it damaged itself at one point

alternatively it could just be a partial clog, in which case maybe i could try a cold pull like you initially suggested

[radiant stone]

Oh that cool!! yeah it could be either, but could also be cos it was crooked, but it's printing now!! Nice work!
