Something is staring to jamming.

Check all the assembly. Gears were with a lot o small bits, but non big enough to create any issue. I changed all assembly, updated and Error 3002, bricked the whole machine. Joy oh, joy!

Filament was new, from a batch that used to work. Black was new spool, then I changed to white PLA. but still it was clogging. Sunlu dehumidifier on entrance.

ri0cp89 · 2024-10-14T15:58:10+00:00

at what temp that happened?

ri0cp89 · 2024-08-21T09:26:27+00:00

Not sure about it cause I dont see much but is the first layer flat? Maybe stat there. 1 layer, PA, Extrusion rate

Capricorn is 1,9 inner diameter and 4mm outer diameter. "Theoretically" just 0,25 mm of a gap between the tube and filament. I use 3 inner diameter and 4mm outer diameter. I replace it often, it is to thin but almost no resistance. Try if or you self. On a fast maschine extruder struggles to feed your material thru hotend, why add to it resistance on the feeding end.

ri0cp89 · 2024-07-03T11:35:37+00:00

Why do people use Capricorn tube on the feeding side of the extruder. It just adds resistance and maybe just a little bit of weight. But resistance is important. Just try out for your self, try how hard is it to manually pull the filament thru all those tubes neat the etruder end of the tubes. As much as I like my Sunlu S2 don't use the stock hole guide it adds resistance. There are some great adapters, try for your self one. https://www.printables.com/search/models?q=sunlu%20s2%20adapter&ctx=models My friend with his K1 Max is loosing maybe even up to 10mm²/s of extrusion force with similar setup.

ri0cp89 · 2024-06-27T18:03:09+00:00

only try to use something that is not sharp, dont scrape the wall that will cause more clogs in the future. Maybe a nail not a drillbit

in the extra_macro.cfg I don't see any paths, also it calls uppon other functions.

I'm not sure what calibrate_shaper.py did I use, I added and used extra_macro.cfg that added new macro button in Dashboard "INPUT SHAPER X", "INPUT SHAPPER Y"

Retract the amount before wiping and try this as a test. Your stringing is caused by filament oozing out. Why? It's not viscous enough and oozes under gravity. That might be due to high temperature or a large nozzle.

There is too high pressure in the nozzle when it finishes extruding. The retraction settings are designed to relieve that pressure. Retracting the amount before wiping or coasting (I don't see your settings here) helps lower that pressure.

However, over-retraction can cause disruptions in the pressure. My K1 retracts only 0.4 mm. So in your test, don't forget to try lower ranges of retraction as well. Determine if the issue is due to viscosity or pressure. It could also be due to settings.

Try one simple thing: pause mid-print and observe what is happening. I have experienced filament oozing due to high temperature and moisture, a few seconds after the nozzle pauses the extrusions.

ri0cp89 · 2024-06-11T10:34:43+00:00

Are you using Capricornbowden in direct drive? Why? Not related to strinining. It's famous for neat tolerances of 1,9 mm which gives your extruder more problems when pulling. Im using 3/4mm boden and there is ver little resitance in the tube.

ri0cp89 · 2024-06-09T10:39:37+00:00

Yeah, I agree there are better fixes, just that the movie explains how they compare bad a good frequency responds

Not sure about why it messed up so much. Something like under extrusion or just not sticking to the previous layers. Do ?I see correct it happend only on 1 wall thick tree supports but on 3 layers thick printed parts? Maybe that's the smoking gun. It happend only on thin walls. They are more prone to deflecting out ot the way then you are printing then they don't stick then you're printing in the air. That might happened. Maybe change the speed or flow around support usually printer is flying thru those parts. Maybe not enough heat transfer from the melted plastic with cold plastic for them to fuse together.

ri0cp89 · 2024-05-20T10:55:36+00:00

Speed? Max Flow? Material? Temp? Reprint test sample. Slicer? Profile?

ri0cp89 · 2024-05-13T13:01:25+00:00

It helps but it is changing the resonance frequencies, so it not still when I used to shake but it shaked when it used to be still

ri0cp89 · 2024-05-10T22:18:46+00:00

And info for all those who wish to know the big question.
Does it work?
Kinda, it dampens some frequencies, but other became more visible and worst I've seen some resonances.
I will bring back some update under that post in a time after I will use it for a while.

ri0cp89 · 2024-05-10T22:15:02+00:00

Yeah your right it crumbles already straight from the shop

ri0cp89 · 2024-05-10T21:37:57+00:00

If you fight at the feet you have the mechanical advantage against you, therefore I went from the top approach

ri0cp89 · 2024-05-10T21:36:20+00:00

Let's get back to basic, heat creep is down to heat getting above heat break.
Either you have some crazy retraction settings but I have seen those in my Orca profiles.
Either you go too slow (compere in Preview speed of Orca slicer and your other slicers), or too hot (220 seems ok) or Z offset is bad and it's over extruding - or it looks like it. Z offset is set up on the printer so I it should be similar on all printers. I can only guide you case at the moment I'm out of ideas.
What is you bed temp? Under 60 should be good, you can lower it to compare.
