Anyone had this issue before?

I’ve never seen anything like this before, especially all these crumbs on the heatbed and around the printer. Could it be caused by the slicer settings? I’m using the same filament as always: JAYO High Speed Matte PETG.

What should i try first?

Printer help

Hi all, after between 7 or 8 years of CR10S ownership I finally decided to get an upgrade (Neptune 4Max) and I've already fucked it up!! it seems I sat it too close to the wall and as the bed went back it got stuck and skipped a load of teeth, I noticed unlike the CR10 It doesnt havent end switches so I suppose it relies on the stepper encoders? I noticed I was having issues when I was trying to do initial bed leveling and it was making a horrible noise as It was I guess overdriving on the Y (inthink) axis skipping teeth because it wasnt lining up, I noticed when it was all the way forward the nozzle was hanging over the end of the bed so not good. anyway I loosed the belt and pushed it back to where I though it looked even, this doesnt feel like a good solution so I wondered if anyone knows how I can make sure its lined up alright?

Thanks :)

Printing issues

Neptune 4 pro I keep getting this error message. Any idea what I can do to fix it, it’s been a bit like this since I brought it and I’ve just persevered with it. One thing that I’ve always noticed is that if you do the auxiliary on the levelling when it comes to do the automatic points it never gets up to temperature and I could be waiting there for days so whenever I do that levelling I always heat the plate first and then do the auxiliary at which point the plates already out of heat that it needs to be and continues To level okay.

Totaled in two days

Got my neptune 4 plus refurbished from a third party seller. I'm not new to 3d printing. I haven't used a lot of direct drive machines, but my ender 5 pro has served me well for years. I got a couple prints out of this thing, but it kept forgetting the z offset between sessions and starting off too far from the bed. I'm pretty sure that's what happened here. On my ender, it would just make spaghetti if this happened. I guess the elegoo version of that is complete self destruction.

Obviously this print head is done. I might try and get another one from the refurbisher. Any advice before I do this again?

Bed mesh help

Got a Neptune 4 max I’ve been fighting with for few months. (See post history) Has been having issues with the extruder clogging after knocking prints off and carrying them around the bed. For history, I’ve had to replace 2 entire extruder heads, and the X belt, as my tensioner was faulty and frayed the hell out of my old one.

Reset everything to 0, let it warm up on standard PLA temp for 30 minutes then auxiliary leveled all 6 screws for 3 total passes on each to dial it in. Did the auto leveling (tramming) and this is the bed mesh. The past few times I’ve done this then adjusted each screw, I’ve thrown the bed mesh off completely and I’m never able to get it within the +/- .2 margin.

I showed a buddy and he said my bed might be warped, how do I go about testing to confirm bed warping (outside this) and fixing this? And the z offset is accurate, I did the paper test and adjusted for very little friction. Need some help before I go to customer service for the 4th time.

Edit: reddit doesn't seem to like me today and wont attach images. Ones of my bed mesh in fluidd, all 4 corners are above .5 and the center is at 0.0. Second is was the numbers for each point from leveling from the printers screen.

Cable qui traine

Est ce que vous aussi vous avez le câble de l'extrudeur qui traine sur le plateau ? Je me demande si ca n'arrache pas mes impressions.

Layer Shifts

I've been having layershifts really bad recently. I feel like I'm pretty good with troubleshooting but I cannot find the issue. I've tried tightening and loosening belts, I've greased the ZAxis rods, I've printed at slower speeds, increased Z Hop, complex geometry and simple geometry. Belts don't have missing teeth, gears are full too. If I put a small amount of resistance on the bed or print head they seem to skip easily. There have been no prints pulled from the bed by snagged print head or anything so I'm not sure what's catching or maybe if my jerk/accel is too high? I'm at a loss

Neptune 4 Plus PETG

I know that every printer is different, but I'd love some advice on PETG settings for my 4 Plus. I've tried tuning my settings. Using the tuning prints, and I'm still not getting it right. I'm seeing warping and very bad print lines. I was just hoping someone can give me a good starting point to try and see if it can help me. Because I don't know where to turn next. Any advice or print settings you use would be EXTREMELY helpful. I'm using Orca Slicer. Thank you.

Buying a Neptune 4 today

Hi, I have the option to use a coupon to buy a Elegoo Neptune 4 , I currently own a Ender 3 V3 KE.

Neptune 4 seems to have good features and a good price, but there are many newer printers.

Opinions on this choice?

Neptune 4 Max - Nozzle hits model

I have leveled the bed many times, checked z-hop, made sure the hot end was tight, flow rate etc. Can't for the life of me understand why it will hit the model after about a few inches. Really thought the z-hop was the issue, but I have it set to be 2x the layer height, but still hits at the same spot every time. So frustrating having such a big 3d printer and unable to print anything beyond few inches haha.

Any ideas or thoughts to try?

Edit: Forgot to mention I'm using PETG, if that makes a difference

Edit2: It appears to be fixed now. I tried all the fixes listed below which were all great suggestions. I replaced the nozzle with a different size and now it's not scraping anymore. Not sure if it was something with the way the assembly was out together that caused it or what.

Random bumps in prints

I bought my printer a couple months ago and it worked perfectly fine. A little while ago my printer started to make all my prints bumpy like they are in the pictures. I have no clue why this is happening, and I have no clue how to fix it. Help would be greatly appreciated!!!

Model: Elegoo Neptune 4 Max

Slicer: UltiMaker Cura

Filament: Elegoo PLA+

Nozzle temp: 200°C

Bed temp: 60°C

Speed: 150 mm/s

Retraction settings: no clue about this one, on my slicer it just says “enable retraction” and I have it checked.
