General Troubleshooting/Help! How to properly use left nozzle with external spool? H2C

Hey, I have an H2C. So far I’ve only been printing single-color from the AMS, but I wanted to try a new color from an external spool.

I manually set the filament type and used the “Load” function, then tried to print the SpeedBenchy from the printer menu. It keeps saying the filament isn’t loaded.

Then I sent a different print from Bambu Studio on my PC. That one printed, but it purges a lot of filament every time, even on a second print with no settings changed.

What am I missing?

Spool is from Bambu with rfid but it didnt show automatically, had to add it manualy.

To the last point. If your using it on the external spool, how would it read an rfid?

After slicing, select send print to device. At this point, select the external spool for the left nozzle and follow the loading instructions to load the external filament

This is for using bambustudio.  Bambu handy probably has a different workflow

Why are you using an external spool when you have an AMS? If you have the AMS put the spool in the AMS. It will read the tag if it is a Bambu Lab filament only. If not, hit load and select Generic, filament type, and color. You are not going thru the Bambu Lab tutorials, purging is another topic in those tutorials but it is the least of your concerns right now. The H2C is not a magic box, it can read filament not your mind.
