Constant filament changes after going to single filament

After using 2 filaments on a print, when it goes to a single filament in A1 mini the printer will change filament to other color then change back every other layer. Is there a setting in BS to prevent this?

Not sure, but kinda sounds like the same or at least a similar issue. I just wanted to start my very first print sliced in Bambu Studio and noticed way to many travvel moves…
Where can I turn that of?

In order to reduce travel moves In Object mode, click on first part (Assembly) in list and put that part in one corner. Then click the next part put it directly above (beside, beneath) then go to the next one and do the same. When finished with that row (column) slide over to the next one and go opposite row (or column). Hope this helps.

Have the same issue with the A1…printed some stuff in dual color and after that even its a single color it begins maybe 10 times to “clean old filament” but why is that?! anyone has an Idea? its really annoying and cost a lot of filament that wasted on that process…

I have the same problem with my new A1.
I noticed that the problem already exists after slicing the model.
As you can see if you take a look at the travel paths.

The presliced prints work perfectly fine, so I assume it’s a bug in the slicer.
Or maybe a misconfiguration, but I didn’t change the default.

I found a bug thats matching to our Problem, deleting the extra G Code for Timelapses helped me out.

Update: Not all printing breaks are removed with the deactivation of the timelaps.
Round about 95-90% are removed, but some stops are still there.
The Display shows “clean old filament" in this case.

I am not near the printer now but do remember 2 settings for “Timelapse”
one was “Smooth” and the other was “Standard” or something like that.
“Smooth” will park the toolhead after every layer to take the picture. And I guess purge and restart

“Standard” just takes the picture at layer change without the park.

I would think Timelapse off it would not do it either.

And this is on my P1P not sure if it is different on the A1

Set the Timelapse off but he keeps doing it …didnt know what the heck is the problem…not on every print thats a bit weird for me…and also if its smooth of traditionell makes no change. Any idea whats going on or what i can try? I feel like its going to be to delete the timelapse G-Code than it has to be gone…but thats not normal to go as far as this for a normal Print.

was this ever figured out my a1s are all doing this and its so very frustrating ruining all of my prints

Removing this block of code fixed the issue for me. No matter what I tried, the slicer was adding almost 30% more print time because of travel moves.

Couple that with my AMS being very picky about filaments (everything is a jam) 3 hour prints were stretching out to over a day.

I have the same problem with my A1.
Something happened, or I made some change, and I don’t know what…
Every print I slice (only one color and with no time-lapse) goes through every layer to purge the filament.
I uninstalled and installed Bamboo Studio, cleaned the settings, but it’s still the same.
I managed to avoid these travels by locking in special mode > Print sequence > By object, but this is not a solution…

Does anyone know anything about this? Thank you in advance

Yeah I just tried printing a snorlax and saw it going to the poop chute back there after every layer. I was like wtf… because I thought it was thinking it had to change filaments… because the file was set up for 4 colors, but I reduced it to one because I just got a p1s and didnt get teh AMS (poor) lol.

so i was like sheeet man is it wasting material everytime?

but yeah the time lapse thing was checked off… so it took a picture of every layer and the nozzle was getting out of the way lol
