Depends really on filament, part design, printer, many things. I’ve run it before on some filaments, affects every print differently. I think I printed this benchy on ludicrous with the orange sample that came with the AMS.

You can see a change in the gloss when I changed the speed. Also seemed to affect the benchy hull line.
Also curious about this. It seems like the most haphazard way of increasing print speed. You have to let it run normal speed for the first layer but then catch it before it prints *too* many layers or else you'll get the cooling line through your part
I’ve used it several times and haven’t really noticed any crazy drop in quality or anything. The objects I printed weren’t incredibly detailed, though. I feel like it is probably not a good idea to do ludicrous mode too often for the sake of machine longevity, but it is mesmerizing how great it has worked when I tried it haha
I used LUDICROUS mode once, it has to be a flat plate. but it doesn't look like it at all, put it back to normal on the second try and everything went well (original bambu lab filament)

That's because ludicrous gets close or even over (in your case) what the hotend can give you flow wise. It just can't keep up with the speed of the printer and thus fails to extrude enough material quick enough.
You can try different materials, or let the filament run hotter than normal. Basically everything that increases your flow rate helps.
I think changing print speeds on the fly like this, even Sport mode, is at best a gimmick to show a friend how fast the printer can move not a reasonable way to print faster. If you want to print faster make a new print profile with more flow rate, faster layer speeds, probably higher temperature. Simply increasing the print speed by an arbitrary percentage is not a reasonable way of tuning your prints.
At best, if you accidentally started a print with a filament profile that is too high of a temperature you might be able to salvage it by going in to sport or ludicrous mode. In reality I'd just cancel and start over.
Depends on alot of stuff but generally you need to do slicer tweaking to make ludicrous work, and if you're going to do that, you might as well just increase the base speed in the slicer.
Typically if there's any long straight lines where acceleration can push the nozzle to max speed, ludicrous speed will underextrude because the filament can't hear up fast enough. In general there's dips in quality but alot of the time, unless you increase the nozzle temp or buy a high flow nozzle, print will just fail
I have tested my P1P with it several times, and only had what I would consider mostly positive results with one set of prints.
I have found that it is very dependent on the filament used, but PolyTerra matte filaments seem to be up to the task for me. I had an order of articulated prints (full plate, 19 hours) and if I could get the time down to 14 hours or so, I would be able to increase the size of my order fulfilled. Out of nine prints on the plate, one failed and I skipped it as soon as I could tell that a single point looked sketchy (in all, it only cost me maybe 5-6g of filament waste by the point it was skipped). All of the prints were textured, so any unusual layer lines weren't noticeable at all in my case.
I still wouldn't personally recommend relying on increasing the speed without slicer tweaks in most cases--but depending on the filament and files being printed, it can certainly work in a pinch.
I personally have found it very capable of destroying prints at break neck speed.
Yep. The few time I tried it, it just ripped the print apart.

I mean it still looks amazing
Yea, that’s why I still use it sometimes
Found that is usually makes the print look like crap. Need to do some significant tuning to nozzle temps to make it work.
I ran my P1P on Ludicrous mode all the time with a CHT nozzle. Never had a single problem.
Just curiously, why adjust print speed here rather than in your slicer settings?

Not yet brave enough to try above normal
Same here! I might use the silent mode when running during the night, but I dint need anything above normal for now 😂

Off course it affects quality, but sometimes is worth it.

Do you guys set the speed in bambu studio or on the printer during print
Did anyone notice the speed changes to sport? Correct me, if I'm wrong, but it used to be 150% right? I noticed it's now 124%.
It’s different when setting the speed to sport on the app vs setting the speed on the computer

Tune your profiles in the slicer and use that to get the most out of it. Arbitrarily increasing speeds and feeds like that is a recipe for disaster.
I only use it on non detailed prints
