K2 Plus CFS system isn’t working for the 4th slot. Using the provided RFID filaments. after 2 successful two color prints, slot 3 is not working as well. Even after manually pushing filament in, it never gets picked up.
I am having the same problem. Have you had any luck getting it to work. Mine worked the first time I loaded the slot but it lost the setting after a short while, not sure when, maybe when I powered down and started back up.
I am having an issue where the creality print doesn’t recognize the spool/color. The cfs itself reads the filament and feeds it properly and shows it is ready with the indicator light. But on creality print it doesn’t show there is a spool in that slot. It is a cardboard spool but it has treated edges. Event with the printed caps, it still doesn’t recognize it.
A quick update on this issue. It turned out two screws were missing on the 4th slot. Guess where I found one of them? Yup, caught in the gear mechanism, it was covered with grease, so not easy to see until I tried to turn the mechanism. The good news is Creality did send me a replacement.
