Why do some 3D printer beds require turning knobs on the bottom for leveling?
Why do some 3D printer beds require turning knobs on the bottom for leveling?
On my ender 3 I have to turn the knobs on the bottom for leveling.
I just picked up a Bambu Lab P1S and it doesn't.
Fundamentally, what is different that allows the P1S and other printers to get away without it?
You're viewing a single thread.
BambuLab wants to be the Apple of 3D-printing. So they simplified and decided the factory bed level with auto bed leveling/compensation is good enough for the user.
On high end printers there is just no need to level them. The factory does it and the bed won't move at all due to the excellent mechanical designs.
Everything else? They have it to level the corners of the bed and use automatic bed leveling/correction to get it perfect and adjust for build plate imperfections.
There is one system that does level the bed but doesn't need the knobs as each of the three mounting points is connected to an independent z-axis (kinematic bed): https://www.youtube.com/watch?v=bgkK7Fez8VU
Good comparison with Apple (no open source anything)
There are some differences on how locked down their (bambulab & apple) ecosystem is:
-
BambuLab talked with the X1plus guys and made changes to allow it (apple would never allow a jailbreak)
-
BambuLab talked with BTT/BIQU regarding the Panda touch The conclusion isn't as fortunate.
-
BambuLab collaborated with E3D.

WebKit is open source 😅 so maybe Bamboo is a little worse in that regard.
WebKit is only open source because they forked KHTML to create it, which is licenced under LGPL
Hahaha fair enough😂😂
