Reddit was like the StackOverflow for life

…sometimes coding too We’re like regressing to friend’s or known in person people’s opinions, because Internet will be full of bot and sponsored content and opinions. Either way, double money for corporations, sponsored content ->more sales; people not trusting reviews and trying out stuff just to find out it’s rubbish ->more sales

I think it would be also cool to have an indicator if the car in front of you has cruise control on

Yesterday after another hour or so I think the printer is back on rails.

• previously my retraction was something from PrusaSlicer defaults so like 5-6mm, now 3,5mm
• I changed the nozzle to a new 0,4mm which gave good results right away (cleaner first layer and no colision by the nozzle with the lower layer)
• an IPA clean mentioned in previous comment worked great. Still one layer of paper-glue stick is used and is helpful
• I leveled the bed with some margin. I always leveled it to fill good friction with the piece of paper, but now, right when the friction starts i loosen the know/spring half of a degree just that the friction is gone.

Gave Cura an another try with this one: https://lensdump.com/a/9ZGlC first successful print from the start of this post

• flow 0,9 and initial layer flow 1,01. In PrusaSlicer it was 0,95 I think
• layer height 0,2
• initial layer height 0,2
• Z-hop 0,3 (sadly had to use it to avoid hitting the previous layer
• top/bottom layer pattern = concentric
• infill 20%
• printing and initial nozzle temp = 210*C
• printing bed temp 60C, and initial 65C
• print speed 40mm/s, and top/bottom print speed 10mm/s
• retraction enabled with 3,5mm distance
• brim on
• Travel Tab: ENABLED: retraction, retract at layer change, z-hop when retracted, z-hop only on printed parts. Yet to try combing mode
• infill pattern = cubic

second successful print (Cura too): https://lensdump.com/a/9ZaX5 :

• only changed initial layer height = 0,15mm
• the print-initial nozzle clean at the bed edge still sometimes gets dragged to the center but it happens partially or doesn’t mess the print and I can pick it up after brim is printed

third successful print (PrusaSlicer gave me warnings about supports needed, but Cira didn’t):

• https://manyuploading.com/nwh2i5jp96w4/signal-2023-07-01-150525.mp4 some clicks of retraction can be heard. They are always there when retracted. Is it ok?
• https://manyuploading.com/5wysd8w1iwvu/signal-2023-07-01-152633.mp4 clicking
• photos: https://lensdump.com/a/9g2rz
• no further settings changed.

Tips/ovservarions welcome and thanks everyone for the comments which I’ve read and gave me ideas what to check/google <3

! this reply is for 30.06.2023 morning state. I’ll post a today’s update around an hour !

THANK YOU for replying. I’m pretty desperate since the r/Ender3 is private and have spent yesterday ~5h trying different settings.

Actually I think I’m leveling to close to the bed. As I described, I slide the paper under the nozzle and tighten the gap to fell much friction. Yesterday with some trial and error, I set the Z-offset to zero and the nozzle was so close that no filament was extruded. I started to make a slight gap as the paper barely drags between the gap and its better this way.

2. As above, increasing the distance was a good idea, the temp. also went up 215/60 first layer and 210/60 rest.
3. I tried placing the magnetic sheet on the glass bed, adjusted the Z limit, but the adhesion was poor. I’ll try it another time, when I’ll make the printer work properly.
4. Print temp increased, first layer 10mm/s rest 40-50mm/s. I’ll try to record how the extruder works.
5. I just found this vid and seems like loading filament to the extruder is a bit of a pain https://www.youtube.com/watch?v=8i4FBZ1jZk4
6. I washed the magnetic sheet with dish soap, but can’t say it helped. BUT cleaning the glass bed with isopropyl alkohol for like 10 minutes to get all the glue stick and gair spray off worked reeeeeeealy good. The adhesion of first layer was right back.
7. I think I unclogged it, but today I’ll try an extrusion test to see if the filament bends or runs straight.

Still ToDo: • Run calibrations for e-steps (printer hardware) and flow rate (the filament you’re using). • Calibrate retraction length using a test print. What’s your current retraction length and speed btw? • should verify that it has thermal runaway protection enabled in firmware.

“I made some printer vibrations dampener” They actually made a noticeable difference in loudness and didn’t cause problems with first 5-8 prints with them: https://www.thingiverse.com/thing:3649851

Pic.1: First layer adhesion is back but after the extruder goes to second layer it colides with the first layer, messes the extruded filament and moves the print around. Pic.2: Failed prints and the final and best since now being print which can be seen on pic3 Pic.3: Enabled there 0.3mm Z-hop at layer change and the layers were 0.16mm. Was looking promising at first comparing to the previous prints that had drags etc. from the beginning. After some height it went crap again.
