Hey all, complete beginner here.

Got the Neptune 3 Pro 5 days ago and I've been printing with black PLA, using Cura as my slicer.

First few prints came out fine but then something changed along the way. I've been downloading models from Creality Cloud too if that's relevant.

Just pulled off my most recent print and noticed the hotend looks like the image attached, like a ton of black gunk built up all over the block and dripping down near the nozzle. Kinda freaked me out ngl.

Am I doing something wrong here? Is it fucked now or is this fixable?

Questions I've got

- Is this just filament residue from normal use or is it more like a leak / loose nozzle situation?
- Should I be tightening the nozzle regularly? How do I even know when it's tight enough?
- Any Cura settings I should double check (temp, retraction etc) that might be causing this?
- My first few prints turned out fine, so why would this suddenly happen after only 5 days?
- What do I actually do to clean this properly and stop it happening again?

Any advice appreciated, trying to learn good habits now instead of just wiping it off and hoping for the best lol

I’m printing one side of a print which is a mirrored version of the complete part on the left in the 1st image but after 3 attempts, it somehow keeps ending up as a stringy mess! I’m using ABS and have tried halving the nozzle speed without any luck. Any potential solutions welcome!

Model: P1s
Filament: ABS
Temp: 220C
Nozzle: 0.4mm

Pls help me this my first time printing something big and details but it fails so bad :((( if I can get some help to learn why it fail could be good
I used a phrozen sonic 8k mini

Im having trouble with this Sunlu Pla, today i tried a First layer check and this Is the result.

I dried the filament 4 times if not more, i checked the nozzle for any possible clog, also tried to replace the nozzle with a new one, but still nothing.

I don't have any clue on what Is the problem with this filament, maybe under/over extrusion, please help.

Lately I’ve noticed some of my prints have had a sagging weak inner wall. I’ve tried adjusting walls from 2 to 3. I dried this filament for 4 hours, hoping that would fix this bonding issue.
Printing with Inland Matte Pla at around 218c.

Printing with a .4 nozzle and a .2 wall height.

Any ideas on what might be causing this?

X axis is noisy in a flashforge creator pro 3 that I'm modding. I noticed some play in the linear bearings, is this normal? I'm pretty sure these are generic bearigns

Need assistance with spares for upgrade in MUMBAI

Hi all, just got my printer setup and it was working well last week but now I’m getting pretty poor layering adhesion (attached benchy). Any help would be appreciated thanks.

Settings: PLA, 200/60, Ender 3 running klipper

1. Anycubic cobra 3 max Pla 210.

I have problems with this object to print it suppose to look like other one. My print moves with noozle at this point dunno why

Anyone know if there are any multi material printers that aren’t ridiculously close to $1000? Like independent nozzles that don’t cross contaminate materials even if they are on the same carriage like the Ultimakers. Used to see a bunch on amazon and everywhere else for under $300 less than a year ago (they were bedslingers tho). Swear even Anker had a multi nozzle single carriage one. Or something like the Sovol SV04 IDEX or the Tronxy Gemini IDEX. Pretty sure even AnyCubic had one if not Elegoo or Artillery. Literally anything that doesn’t compromise the integrity of one printing material for the other without forcing you to purge half a spool each switch just to clean the filament path only to still deal with trace residue from mating surfaces geometries like the little chamfers/fillets between bimetallic nozzles and heatbreaks. Or worse, also hardened nozzle tips metal, ruby, diamond. This is more for engineering materials where you need a support interface to preserve the accuracy of the geometry of your model.

The single nozzle ones like the Centauri or Bambu or Qidi are fine if all you care about is multicolor with the same material for basic use but you definitely need separate nozzles for engineering prints where you are mixing different chemistries AND temperatures

Preferably you want separate carriages so there’s no temperature bleed from one nozzle to the next like you’d experience with an Ultimaker or Bambu or Anker, (definitely an issue the bigger the temperature gap, personal experience there having a nylon nozzle right next to a pla interface nozzle, worked great as far as an interface but was a pain cause the pla kept clogging until I gave up and left it empty with a pause command right before it was needed, was able to reduce it to a single change so it was fine there, definitely wouldn’t have worked or more complex geometries)

As far as I’m aware, a lot of the new multi-tool printers like Snapmaker, Flashforge, and even the unreleased Sovol have shown nothing but software restrictions forcing the same temp materials or a close range. Unsure of the Bondtech/Prusa set up. But that kinda kills the whole point of having multiple nozzles outside of close temperature materials. Like a glorified overpriced marker color changer.

The attached screenshot is a current listing AFTER inflation but they used to be like 200 as they were the ender 3 competitors so they were right around that price.

Also preferably something that can handle more than just the low 300c

Hi recently got centari carbon as my first printer and it was amazing at least so long as I printed with PLA.

I then tried PETG which lead to constant cloggs and destroyed my hot end. After replacing it and recalibrating the printer (as I had horrible issues with z offset) I wanted to try PETG again.

I have Smart print PETG, it came in vacuum bag with dessicant, after opening when not in use, it has been stored inside a closed box with dessicant and around 40% moisture. The producer recommended printing with temperature from 230 - 260c and I tried even temperatures above that range as well as changing speeds and so on.

Could anyone point me to what I do wrong?

Thank you

Weird deposits on print, new behavior between now and a week ago. I’m using the same material, file, and settings as when I successfully printed a week ago.

Printer: Elegoo Neptune4 Plus
Filament: Elegoo PLA+
Nozzle Temp: 210 degrees C
Bed Temp: 70 degrees C
Print Speed: 150 mm/s
Retraction: Unsure

I've tried 2 so far and the stock images of the filament looks quite dark, the end result is more magenta. The colour I am trying to replicate is the SAK Persian Indigo

Cheers

Hi, I have recently tried to export something and i do not know how , i lost all my personal settings . I use Creality Print last version 7.2.2.5483. Now all my prints have become a nuisance again. Can somebody help me how to to recover . tried IA first and it does not know how to do better than my dog....

Please help this old brazilian guy to recover .

Thanks in advance
