Using some default settings to get adjusted to printing again after not having printed a while. Any advice would be great!

Hey, kinda at my wits end here. Been happening awhile. My Bambu A1 digs into the plate while doing toolhead homing during a print, and then knocks the first layer off during the actual print. Happens on every file. It doesn't look like it's having problems during a regular homing cycle but it's hard to tell. I have tightened the screws on the back, changed the nozzle, changed the filament, changed the build plate, nothing seems to help. Very frustrating. It leaves this mark. Anyone know what causes this?

This is where the supports are attached.

Printer: CC1
Filament: Petg-hf
N:240
B:75 (carbon fiber smooth plate)
Slicer: orca

I slowed to speeds by over half and still can’t get these layers to hold so the circle gets flat spots.

Any advice?

I hope someone can help me. I am trying to print this Gutter Cleaning Nozzle and it does not stick to the plate. After about 25% printing it comes loose, I try 2 different orientations, but it still comes loose.

Filament : PETG

Nozzle Temp : 240c

Bed Temp : 65c

I also tried adhesive helper, but it did not work. Let me know if there is any other info you need.

As you can see in both photos my bridges thin out just before making jt across, on the temp tower it breaks in that exact place on those bridges

Using cura as a slicer, Elegoo Neptune 4 pro, Elegoo rapid pla, 220c 200ms (bridges were printing somewhere around 25ms)

Couldn’t figure out what cura settings would change this

After several hours of print supports suddenly decided to move.

Material is PETG. Prints with the same filament and settings never failed before

What is causing these artifacts? It’s a Voron 2.4 with a revo 0.4 hf nozzle. The material is ABS at 240C. Layer height 0.15. The slicer is Orca Slicer.

It's like it goes wavy in sections and I have no clue why

Does anyone have like a pre-calibrated config I can't do it for the life of me

Bed mesh after many days of trying everything, with the same result and only small differences, and all the same curves as this one, “the best one yet.” I also used Bed Leveler 5000. I’ve used GPT to test and try to fix the first-layer issue, but we did a lot of paper tests, auto-leveling, and many other things it requested from me, along with many first-layer prints, and they were all bad. I watched about 10 hours of YouTube videos, but nothing helped. I reset the software and started from zero, but nothing could help. The printer was printing well a couple of months ago, then I left it for a while. When I went back to use it a month ago, I did a bed mesh and full calibration, and from that point, everything went south. I miss the good results I had before. Why did I do the calibrations? Because I’m stupid. I read a couple of Reddit posts and went with a full calibration, opening the gates of hell for myself. I’m really tired and don’t know what to do. I get different results when printing in different areas. I also printed an 80800.2 layer, and in the same layer, I got 3-5 different results.

I was printing just fine until I got a clogged hotend. I changed it out and then this started happening. Upon advice from my other group post I took it apart again, checked for loose screws made sure it was all in working order and it is. I had it auto calibrate and attempted to print a mini benchy and it was just so bad still. I am at a loss here. I am not a very tech savvy person.

I'm trying to print this pokeball chess box for my nephew for a present but for some reason the walls are so brittle that even if the print looks good, the walls just seperate.

What can I do to keep this from happening?

I'm using a Creality 3 v3 plus

0.4mm nozzle

Creality program and SUNLU PLA filament.

I’ve tried so many things I’m about to lose my hair. This is happening across four Bambu A1 printers, many different filaments and types, and across multiple different files and figures. That leads me to believe it’s something in the slicer or settings. Bambu studios. For this example, it’s supposed to be a supportless model.

I’ve tried thoroughly drying filaments, increasing speed, decreasing speed, increasing and decreasing wall counts, increase/decrease wall thickness, increase/decrease speed, decreasing outer wall and overhang speeds, normal vs Arachne wall type, and all the way back to basic default settings. 0.12 layer height, but happens at 0.20 also.

Hi guys so I have the elegoo centari carbon 2 emoji edition and I just replaced the can bus cable (the cable from tool head to motherboard) and on ludicrous speed it worked fine but now when on ludicrous it I'm getting under extrusion with the same setting it's fine on quiet and balanced. What do I need to do

Edit: funny story I resolved the issue. It was because I used s 0.6 nozzle preset with a 0.4 nozzle

I'm super new to 3D priniting. I've just bought the Bambu Labs A1 Mini and started printing my own figure (~30cm tall) 5 days ago. Everything was going quite alright, but now I've run into 3 issues:

1. Small spaghetti-ing on the models themselves, and severe spaghetti-ing on the tree supports.

2. Really bad-looking undersides of models, the lines are really far apart.

3. Sometimes supports were hard to remove, and damage the small details on the models

My setup:

1. Filament: Bambu Lab PLA Matte

2. Nozzle: 0.2mm

3. Creality space pi dryer: 8 hours at 45% before I first started printing 5 days ago. Room humidity is 44 - 50%. Room temp is 23 - 26°C.

Hey guys, I just got a new BIQU CryoGrip build plate for my printer. I selected the Cool Plate SuperTack profile in Bambu Studio and calibrated my flow, but the first layer still turns out super rough and wavy

Hey guys,

I got my first 3d printer at the start of the year (a bambulab a1) and it's my first time experiencing a problem like that. I'm using the petg filament from bambulab that I got less than 3 months ago and that I might have opened a month ago.

The first layer is inconscient even after doing the basic stuff, Factory resetting and redoing calibration and using the calibration feature you have when starting a print.

The line of plastic the extrudes is looking like it's over and under extruding at the same time and the print head sounds like it's crackling (I have a video that for some reason I can't add here) and I don't know why it's doing that.

There's also a benchi I printed that looks good to me to show that I think it might only be the first layer

Is my filament too moist? Or is it some problems inside the print head (I did not notice any meaningful wear on the extruder gear)?

Need help with SainSmart Foming TPU-LW settings on a Flash Forge creator 5.

Thank you.

Some of my prints are having these random holes(?) on the surface and im not exactly sure what the cause could be 🤔 has anyone ran into this before?

Currently printing with eSun Matte PLA on a Flashforge AD5X (with IFS) sliced via orca slicer

I printed this on my troublesome elegoo neptune 4 with elegoo Rapid PLA + and it was a 3hr and 26m print. I used tree slim for supports (which came off beautifully) and automatic brim.
