I accidentally got the PETG filament instead of the PLA which I normally work with. I have an Elegoo Neptune 3 Pro.
Here’s what was weird:
-
The test strip went across the bottom of the board instead of the side. It went back to the side when I put the PLA back in.
-
The temperture melting point changed automatically from 200 F to 220 and then back again when I switched back to PLA.
Does the printer know what kind of filament I’m using and if so, how?
ETA: The filaments have all been the Elegoo brand filaments.
Unless you changed filament type presets in your slicer, the only way the machine would know is if the spools were equipped with RFID tags and the printer has a matching reader. Bambu infamously does this but to my knowledge Elegoo does not.
I couldn’t have changed the settings because I thought it was PLA. I noticed that it moved the test strip, but thought it might be because they didn’t want to always go to the same spot or something. Then the supports were acting kind of weird, so I really checked the specs and discovered I ordered the wrong filament.
Bambu is infamous for that? I can’t be assed to tinker with settings and print a million times to get it right. The rfid stuff they do is a godsend for me and surprised others wouldn’t like it
It’s a transparent attempt to lock you in to buying their filament. If you want to know how the community at large feels about this, just go to your favorite objects repository and see how many solutions people have developed for ripping the RFID tags out of the Bambu spools and integrating them into spools from other brands just to make the damn machine happy with it.
It really doesn’t add any “godsending.” It’s not difficult to, when you stick a new spool of filament in the machine, tell your slicer what that spool was. It’s not like you’re changing spools every 30 seconds, especially if your machine has some manner of multi-spool box like the AMS or various other brands’ versions of the same.
