Here is the link to the excellent RFID for CFS tools.
DnG-Crafts is showing us the future. I hope that BigTreeTech supports an open standard with the VVD and that all CFS style machines get this feature.
Hello mcjamez,
I don’t have a need for for a CFS, but I am interested to look into the GitHub files as I saw Arduino mentioned and that is right up my alley.
Cheers.

I also can confirm that new version of Android-app works writing RFID labels for new CFS firmware.
Yes, it is used only to find out default filament type and, even more important, the color.
For non-CFS users they can identify still the spool on the RFID reader of the K2 on the side of the spool holder.
The RFID tag is not used to track the usage of filament (even if it would be possible to do it because you can access this information on the mainsail/klipper interface of the printer which is done also by CPV6 where you can see some infor as well instead of directly on printer).
It helps the CFS to calculate the available filament on spool becuase when the filament is loaded it measures how fast the spool spins (measuring time between passing of RFID) and then calculating with the spool size (which is written on RFID) the available filament amount to show. This works only in CFS of course.
Anyhow, I create for all filament (types/vendors) my own profiles where I set the right print temp, PA, max flow rate, flow rate and bed temp … and I need to change in the slicer the filament type from ‘General …’ to whatever it is.
I have > 100 filament rolls from ~15 different vendors and seldom use normal PLA(+) other than for fast prototyping but even then I use for example Elegoo Rapid PLA which prints faster than Creality Hyper PLA @ half of the price.
I have also some SUNLU/JAYO filament (JAYO & SUNLU are the same, JAYO is just the 'cheap brand and SUNLU the bit more expensive original brand) and I may test some newer filaments like the high speed matte PLA/PETG or so because I hate the normal glossy PETG look.
My experience is that If I get very high discounts for some filaments it most of the time does not fulfill all promises and they just clean off stock!
Are you aware of Filament Sync?
I haven’t tried it yet (broken K2 waiting for spare parts from Creality) but it looks promising.
Make sure you read the whole readme because it requires another repo that must be installed on K2
Yes, but I did not install it because it is a bit too heavy mod and I have only one K2 and some other printers and switching a lot between Orca and CP6 because of some CP6 bugs (especially with support).
I would prefer an Orca-Addon or so which would handle that without a printer mod.
Unfortunately, it is impossible to happen just from the slider. There has to be something on the printer side to talk to. Besides, the mod is not that intrusive, as long as you make sure not to go crazy and start installing things via entware that could potentially break dependencies with creality’s print server.
Regarding filament usage, have you tried Spoolman?
There’s native support in moonraker and by creating filament profiles with IDs that matches Spoolman’s, you can insert the Spoolman macro to set active spool on filament change gcode section of the slicer

That’s pretty slick, thanks! I too am very much desiring a single place to interface with the K2 including filament management. Orcaslicer looks right, but I haven’t had luck getting a really solid configuration yet.
I feel like the K2 could really use a concerted community effort to put all of these Klipper mods together for a much improved version of what Creality releases. I’m impressed with Crealities current efforts, but Klipper is just calling out for all of it’s nice to haves to be put together for the K2. We’ve got the open firmware advantage over Bambu, we should use it.
