This may be useful information for others who don’t have a filament sensor in their set. Thanks for sharing. Coprint could indicate this on their Wiki page.
Yesterday I printed a solid black, with a poor quality filament that breaks. It did break, and the printer stopped, saying it ran out of filament. The interesting thing is that Fluid didn’t indicate this, only the printer. I just threaded the new filament up to the feeding extruder, then pressed continue printing, and from then on it automatically threaded the filament all the way through without error and started to throttle the printing. Then the same thing happened as you, that it stopped printing, printed a big blob on it, and started to continue printing. I think this could be due to 2 things, either it needs the flushing tower for 1 color, or the macro for restarting after filament runs out is not perfect. Or it could be that the parameters related to these are not good in one of the CFGs.
I figured it out with help from discord. Co print has yet to answer questions.

Coprint support answer to my query about filament breakage was;
Generally speaking, after pausing the print and changing the filament, the machine should squeeze out the excess filament at the waste slot and then continue printing.
They asked me to record a video
I think it primed the nozzle on the print rather than at the “waste” spot
I noticed, because I noticed right after you wrote this, that when the filament ran out, the head came out completely to the right, and it pushed the tray all the way, and when I inserted the new filament and selected continue, it still extruded about as much as it had, even on the print. It’s like it did it twice.
I need to record it for co print support, but I’m so busy printing I can’t find the time to do it ;D

I use a camera, but since I stopped printing, the timelapse video was automatically deleted. But I will record the reloading the next time the filament runs out. The error is in the G code in the macros. You should also try running out with multiple colors. I will experiment with it when I have time. Can a rinsing tower be assigned to a single-color print? I also asked this question on Discord, but they couldn’t answer it for now.
you could tick the box, but no purge tower would be generated if there’s only one filament

In principle, the KCM set only works well with the Orca slicer. This is also highlighted in all installation instructions. There is no Coprint profile in Creality Print, and it is not possible to add one. There may be an update for it in the future, but as far as I know there is none. Install the latest version of the Orca slicer and try printing with it. Installing Chromahead will reduce the printable area, but there is a solution, although you have to replace the print head carrier with a modified one.
In one color you can use Creality Slicer , but with 2 or more colors no.
The reduce printable , its the problem i have. and it not in the creality store info, .
use @frause head carrier

and modify the cfg files to recover lost space

Filament change video;
Note, I inserted the new filament before pressing retry.
It worked as expected

I made a video too. I used it with two colors. It did the same thing as you. However, if I use only one color, then on top of that, when it goes back to print, it goes towards the print and extrudes a huge blob onto the print, then continues printing as if nothing had happened. But this small mistake is also annoying, because as you can see, it got stuck in my head. A short while later, after I stopped the video, it tore up the part that had been printed so far. https://www.youtube.com/watch?v=J8urTub8q4E
it would be great to be able to share thios with creality support
can you put it on a google drive ?
That’s the way they asked me to do it, so I could share it with them

I’ll upload it when I get home, but in the meantime it’s available on the YouTube link. Does Creality need it too, not just Coprint?

I sent them the YT link, we’ll see how it goes
