It doesn’t happen all the time, but it happens often enough to make me reconsider buying this printer. The extruder nozzle grinds into the prints as it works, causing either patterns etched into the print that resemble the inverse of the infill pattern or the print to fail outright. At this point I …

May you show us your print defects? I guess you need to add a z-hop to your slicer settings but it’s not clear for me. What’s your 3dprint skill level, are you aware of settings like z-hop?

I’ll try adjusting my Z Hop from 0.4 to 0.6, but I’m unsure what that will do for this. It’s only grinding BECAUSE of this. Round prints like those fidget balls and characters like the baby dragon print perfectly. It’s just long flat prints that give me grief. [IMG_0537] [IMG_0531] [IMG_0533] …

Bottom, it’s a bit hard to say but it seems your nozzle is too near to the bed. ( I don’t know if there is a possibility. Probably on the touchscreen live z-offset while printing?) Top surfaces are rough because of support structure or not enough top layers. Increasing the top layers would help, l…

Looks to me like it could be over extrusion. Also agree with the over extrusion comment. What did your 1st layer look like?

I’ll be the first to say I’m no expert but I’ve spent a great deal of time on my Elegoo Neptune especially after converting it from Merlin to Clipper and seen some oddities. I’m going to second the extrusion issue or maybe a filament problem. Does this look like this when another spool of filament i…

Heres some video of the issue I am at a loss at this point.

I checked with our print-process guys and combined other tips from the thread—what you’re seeing looks like Pillowing defect. The core idea is to use the process of elimination: [img_v3_02tf_89816b36-5d0b-4b10-a617-e397c4427aeg] 1.First-layer issues (1) Filament gone bad? Re-print the same file …

I’ve done that; I have used Snapmaker filament, Polymaker filament, and eSun Filament, and it’s the same issue. I have done all of the calibrations I could possibly do, both the built-in ones and ones that the fine folks in this group and Reddit have suggested, and it’s STILL THE SAME. Mind you, the…

Thanks, I printed you small guy and it had just one tiny lil bump in the top right corner, so I got brave and tried to expand it to most of the print bed. First attempt the printer decided it identified as Chef Boyardee! Spaghetti everywhere well that was after it split the first few layers in half.…
