had several failed prints recently, couldnt figure out what was happening… so i spent all day babysitting the printer to see why the supported arms of a figurine kept snapping off… turns out the bambu slicer was doing funky stuff with the supports… for some reason the slicer is trying to build a support of say 1cm wide at the base… it then tapers down to a smaller size, before mid-support deciding it need to be like 1.5x the original size…which the printer just attempts… leaving a semi detached support that just snaps off 15minutes later
am i doing something really wrong here? im only even playing with the support settings because the default downloaded profile from makerworld was having the same issue… but i can only get the supports to build properley by choosing tree hybrid(which will fix this print… i found the support was only 2 weak because i had my enclosure shut and i have just discovered 500 hours in that this is a nono for pla) but i feel like the slicer should never be trying to do what it is doing?
it’s not. Under certain circumstances it can be but most of the times it isn’t.
It depends very much on ambient temperature. If your printer is in a room with a low ambient temperature, you will probably get away with having the enclosure shut. However, once the summer comes, you may well run into trouble.
well im still having temp issues, but that wasnt really my main problem… the bigger problem im having is strong mode supports making these decisions to just make the support column 50% bigger in 1 layer, something that just seems like a massive glitch but the only settings i changed are in the screenshot
Have you tried changing the wall generator from Classic to Arachne? I seem to remember seeing some bizarre tree supports when using the default “Classic” generator.
Alternatively, try turning the model around by 45 degrees and slicing again.
This is also the reason why it is recommended to remove the lid when printing PLA 
One of my reasons for using the CryoGrip Frostbite Plate. The heatbed only needs 35C instead of 60C, so the chamber heats up less and everything can stay closed. Which also means less noise. And, of course, lower electricity costs. This is definitely noticeable over the many hours. And everything sticks greatly on the plate.
Had a power cut in the office for 10 hours, then the printer started up again and just kept going, the print piece was still stuck in place. You can forget that with the normal PEI
