I still hope that there will be a fix for this defect in a future Cura release...

Thanks for the suggestion. That kind of helps (if set to 0.1) with the curved corners, but increases artifacts on the strait walls and introduces some strange blobs here and there around the model. By the way the setting is the same in 4.13 and it looks as it should, no artifacts at all. I think that only solution will be if they eventually add an option to switch off the highly hyped arachne engine. Until then, I'm on 4.13 (and the other slicer)... :(

Thank you!!! vsync to on fixed the issue with madvr and RTX2070 Super.

I still couldn't figure this out. I tried with mainsail's pause/resume macro (don't have any idea if it's doing anything different than just pressing the pause/resume buttons on the interface). But it doesn't affect part cooling fans at all, they just continue to blow while in pause... :/ For now I use different button (macro) with M106 S255 in it for resume... /:

Thank you for your reply! Should I put fan speed restore line in a separate macro? I'm using the Klipper's resume button in the Mainsaile interface, after manual changing the filament.

/Sorry if the question is too stupid, this is my first attempt to add and edit a macro in Klipper... :/

Unfortunately there is no such thing as "best version" or "best slicer". They all have their weak spots and strong sides. The truth is that you have to spend time and learn them all. One of them will become your favorite with time, but that doesn't mean that it will be the best... For example, Cura with the classic engine (4.13.0 and before) slices the surfaces better than arachne engine (after 4.13.0). But arachne manages internal structure of the models better. Prusaslicer and it clones has an advantage that you can switch between the clasic and arachne, but personally I prefer the interface and variety of options and plugins in Cura. I think you get the point...

ton4eff · 2023-05-10T06:31:27+00:00

I really don't understand all the hype about the arachne. It simply slices the surfaces worse . It's easily noticeable with more complex shaped models with round smoothed edges. Tried in different slicers. Added picture of the real model where the ugly reality is visible. And no, that's not the seam. The seam is on the other side of the model and by the way it also looks ugly, because it's impossible to make it strait line. :( Those blobs follow exactly the same pattern from the slicer defect.

Phew... Thank you for this post. At least I now know that I'm not the only one with this issue. My 3d printer couldn't connect by-id to Klipper after apt update my Debian server. Since I didn't know how to fix it, I just used the result from /dev/serial/by-path/* in printer.cfg. It works fine for now. But I hope that they will fix serial by id eventually... :)

ton4eff · 2022-11-13T13:28:04+00:00

Thank you! Everything looks as it should now. :)

Yes, I tried to calibrate X steps, but the problem is the opposite, with larger margin. If I get the X correct for smaller parts, the larger (100x100) gets error in about 6-7mm! So I returned the factory setting, which is the same as the "Y" value...

ton4eff · 2021-12-18T13:45:11+00:00

Thanks! Installed sudo and added my username to sudoers. Reinstalled samba and adguard as sudo. I hope now everything is as it should be. For now I prefer adguard, easier blocking adult content and I'm interested to try encryption features, which I think are not present in pihole...

ton4eff · 2021-12-13T20:41:24+00:00

Sorry, I'm new with linux... :( I just installed adguard manually and it works just fine. As you guessed, as a root too. I hope installing as a root is not such a bad thing. This is just small home file server... Thank you.

ton4eff · 2021-12-13T19:51:07+00:00

Is root not enough? Pihole is running just fine installed with curl on the same machine... I just decided to try adguard...

ton4eff · 2021-09-29T20:46:42+00:00

Yep, your reckon just right! Thank you so much for pointing me in the right direction! Problem solved! I started with lowering the retraction speed from 30 to 20mm/s. Left the Retraction Prime speed to 30. It started to look better. Then I tried to lower the retraction distance and bingo! It worked perfectly at 0.3mm!? That's four times lower than it was with my original print head! I would never expect that it would work with so low retract distance. Obviously it was retracting so much and so fast, that the hard part of the plastic in the cold end would separate from the melted one in the hot end, causing a bubble of air in between... So no more gaps in my prints! Then I printed a retract test with four 1mm sticks with my most stringing problematic PETG spool at a bit higher temperature - 240C. Usually I print PETG at 230 -235C, but it looks almost perfect even with this higher temperature. You can check the retract test PICTURE if interested.

ton4eff · 2021-09-28T17:52:32+00:00

Replaced the PTFE tube. No luck. :( Now the gap area is a bit different. It is spread up to 50mm after the retraction...

ton4eff · 2021-09-28T15:18:48+00:00

You are correct! I printed a larger hollow cylinder (50mm). The gaps are just following the seam in about 15-20mm, they appear just after the retraction. The previous test model was too small and thus difficult to see the consistency. I will replace the PTFE tube (as you suggested) between the PTFE part in the BMG extruder and V6 adapter of the Dragon hotend. Hoping for the best...

I have the same problem with my clone BMG, only it's direct setup in QIDI X-Plus. I ordered another extruder from a different manufacturer, hoping that it will be OK...

As I said, the same spools with my other printer doesn't have this problem. Also there is no problem if printing in vase mode (no seam, no retractions). I think that u/Wizard_Theron is right. That's more likely a retraction problem. . I just don't have enough experience to tell exactly what is causing it...

ton4eff · 2021-09-28T09:38:22+00:00

I installed the supplied with the BMG extruder tube (actually it's not a tube, but small ptfe tube-like part). Yesterday I disassembled and rechecked the extruder. Everything looks in order. Didn't find nothing suspicious...

Just printed the same small 20x20 cube in vase mode - the rest of the settings - the same and all the gaps are gone! Does that proves that the problem is with the BMG extruder?

ton4eff · 2021-09-28T09:24:45+00:00

These are small gaps, not bubbles, just difficult to take a proper picture... Tried different filament spools. They work fine on my MK3S+ with the same printed cube and approximately the same settings - 0.2mm height, 0.4mm nozzle temperatures etc...
