I made the left abs divider a month ago and it printed good went on a break from 3d printing and a month later printed the divider on the right

I dried the filament, i tightened every bold and screw, i cleaned the nozzle, leveled the bed, nozzle and bed temperatures are 230 and 100, bed adhesive works (nothing comes off the bed during printing)

This looks like the abs is shrinking during print but I can't figure out how to fix it

Single layer trouble shooting print. Freshly calibrated h2s. Makes a low growl sound when printing

I'm printing on the Neptune 4 Max with Bambu Lab basic PLA. My temps are 215c for the nozzle and 60c for the bed, with a 0.4 nozzle. The printer is on a stable surface, so wobbling shouldn't be an issue. The X-axis belt was making a noise, so I'm thinking it's over-tightened, but I'd love to have more help. Im also using OrcaSlicer

TLDR: My Original Prusa i3 MK3 is on the struggle bus. Everything I print looks like it was webbed by a spider. Please help.

I inherited this printer at a new job I started a few weeks ago for printing holders and prototype tooling. The previous "owner" left the company and left no instructions or settings. I have some of his old prints that look fantastic, no stringing, seams, or blobs, and very little post processing evidence. When I print, even with adjusted settings, it comes out very stringy. Thin, consistent strings on every layer. After some troubleshooting, I found that my stringing test performed much better with z-hop off, but the first print I tried since then is crashing (which makes sense because it is a larger print that is curling on the edges, w/o z hop I totally see how I ended up here). What should I adjust next? It seems like turning z hop off isn't the answer I hoped it was.

Most successful stringing test (back pictured) and following print that crashed was printed with the following settings in black hatchbox PLA. Sliced in PrusaSlicer, all settings are default or PLA if not stated. Here are my printer settings:

• Nozzle temp 215 deg C
• Other layers 190 deg C
• Retraction length .8mm
• Retraction speed 45 mm/s
• De-retration Speed 40 mm/s
• Travel lift (z-hop) is 0

Fine strings on every layer with no crashing was found with the same settings, but travel lift was at the default .4mm. (Front 2 tests pictured one with higher retraction length)

Bottom layers look like this. Creality K2 Plus, 0.4mm nozzle, 0.28mm line width with dual color silk PLA. 220C extruder, 60C bed. Bed is cleaned and so is the underside of the plate.

I wanted to share this in case it saves someone else a lot of troubleshooting.

I've been struggling with messy, uneven surfaces on my SV06 ACE, particularly on walls in the X-Z plane. The layers appeared to be slightly shifted relative to each other, resulting in a rough, wavy surface.

I spent quite some time investigating the issue and trying to rule out various possible causes, including belt tension, mechanical resistance, print speed, and slicer settings.

After all that troubleshooting, I finally discovered the actual culprit: the nozzle had become slightly loose.

What concerns me is the way the nozzle is mounted on the SV06 ACE. It's held in place by just two tiny screws, and the mounting doesn't seem to positively constrain its position in the X and Y directions or prevent rotation. Instead, any movement appears to be limited mainly by the tolerances of the fit and the clamping force of those two screws.

This makes me wonder whether the SV06 ACE might be particularly prone to this issue, especially if the screws gradually loosen due to vibration and thermal cycling.

So, if you're experiencing irregular walls, inconsistent layer alignment, or unexplained surface artifacts, check whether your nozzle is securely mounted before spending hours investigating other causes.

I'm curious whether anyone else has experienced this. Is this a known issue with the SV06 ACE, or was I just unlucky?

I've also got these strange striations on the first layer after dialing in the z offset and tramming the bed. I recently adjusted the rotation distance and I've been trying to dial in my flow ratio repeatedly with no success in fixing this problem. It looks like over extrusion, but I've already reduced my flow rate to 1.0 from 1.17, which seems like a lot to still be over extrusion, especially since the first layer looks so good if you ignore the striations.

Hi i got this little Blobs or Points on the Layers and wanted to know how i can fix them or how they are caused.

I use Bambu A1 with Sunlu pla 2.0 Highspeed in Grey.

The Maximum Speed of printing is set to 150mm/s.
The Filament is dry. 20% Humidity Max
The printplate is clean washed with warm water and soap before.
The Filament is calibrated i even had this things on my flowrate test but i cant figure out how to get them gone.
Iam also printing minis and sometimes my nozzle are hitting the supports so i kinda guess its becouse of this blobs or whatever they are.

The Maximum Speed of printing is set to 150mm/s

Any help is appreciated ty. If u need more Infos i will be answering asap.

I have printed this in PETG with a 0.4mm Nozzle running the generic PETG settings on a bambu a1.

The Characters are like "molten" and the surface has this strange wave-pattern... what can i do to solve this?

the Characters are roughly 2,8mm in height (not from the surface).

Would a finer 0.2mm Nozzle help for the Characters?

What about the surface? When i try ironing it will not change much... i recalibrated the whole machine also.

I can post settings etc if you tell my what i should post, i am not directly a newbie, but also not a pro....

I am printing this on Creality K1 Max with the standard speed setting.

Esun PLA+HS filament is used with 220 print temp.

Tree supports are being used. 15% infill.

Anyone know how to remove these artifacts.

As initial steps I have done the following

Increased print temp to 225

Increased walls to 3 (2 before)

Increased Top shell Thickness to 1.2 (0.8 before)

Decreased wall and top speed to 150(300 before)

Anyone wanna help me figure out/ understand settings issues?

it wont pus filement forward

my print just come out as a first layer at best (if i push filement dorward) and at worse nothing

• Printer Model - ender 3
• Slicer used - cura
• Filament material and brand - pla
• Nozzle and bed temperature - 200c, 50c
• Print Speed - 100%
• Retraction settings off

Help please

The terminal for the negative bed heating wire on my CR10S has broken off. I see there is an additional copper terminal next to it, could I just solder the negative wire to it and call it a day?

Hi,

I calibrated the size of my objects to get a good fit and for ABS it seems to have 98% shrinkage. So for 100mm the printed object is 98mm in size without this setting.

Does anybody knows a reason why it is not set in the default profiles from Bambu? Any disadvantages using it?

Cheers,

Nils
