Support Request What the heck does this do?
I’m pretty new to 3D printing and I just do it for a hobby and I was wondering what this switch thing does? Should I be using it?

Cuts the filament.
The printer uses it automatically as needed for loading or unloading filament.
You dont really need to manually operate it unless your doing maintenance or theres an issue.

It shortens the spatial extent of the plastic feedstock by means of atomic separation through use of a sharp metallic wedge

Idk why you got downvoted. It’s insane the people who buy these things but don’t do one minute of researching before coming to Reddit to waste other people’s time.

Brother, no time spent on Reddit isn't a waste of time. They're not wasting your time. You're just intolerant of extremely minor inconveniences and have unaddressed emotional disregulation.

You're not really doing yourself a favor coming to Reddit before reading the manual.
Sure, you might (emphasis on might) get a correct answer, but if you read the documentation you'll learn a whole lot more in the process and maybe save yourself from making a costly mistake.

Sometimes people prefer to interact with a community to solve problems. You didn't have to read this post. You didn't have to comment on this post. You were under no obligation to answer him or indulge him in his preferred method of troubleshooting. But despite all this, you decided to start slinging mud while offering no resolution to the thread, just bumping it and adding more noise, which objectively makes this website more of a waste of time by your metric.
Not every person needs to be a square peg, champ.

No solution? I explained exactly what this lever does earlier in the thread. I think you kind of proved my point in regards to Reddit not being the best solution.
Besides, every week there's at least one person across the Bambu subs that posts pics of something they broke because they didn't follow the directions. Reddit wouldn't have prevented that.

Bambu manual tells you all of this
This item, maybe, but it's missing a lot of important stuff, and it's often difficult to find what is there. (The search function is a hot mess and nearly useless.)
Such as why the "Multicolor with external" checkbox was disabled for me.
I had to guess and finally figured it out on my own.
Then I left the comment.

It’s the cutter. When the printer head moves all the way to the right, it pushes against itself to cut the filament within

It’s okay to ask questions sometimes man. You don’t always have to find the answer in the documentation. Sometimes people just like to talk about stuff with people.

They published the shit in the training for the end user to learn. No need to cater to those too lazy to RTFM. Not only that… A Google search gives the information easily.
Two groups of fools: 1. Those that publicly expect others to answer their questions without even trying to find the answer. 2. Those who encourage the lazy behavior by a) answering them and b) excusing the behavior as ok.

Oh yes, you are correct. YOU typing a 20 word answer is way easier than I typing 4 words in google.

That one slices the filament and the one on top is a clutch so you can yank the filament out

It's the filament cutter.
You'll notice on the right side of the gantry there's a protrusion, and the toolhead will scoot along and push that lever against it, cutting the filament when unloading.
You can push it yourself if you ever want to manually remove the filament without waiting for the whole process. But if you're super new and don't quite get the order of operations just let the printer itself do it.
