Hi, Can you provide print pictures or videos?

i did make a little testprint with change the 3 colors its with original geeetech firmware only its a magnetic bed of creality

i find the problem the steel balls where tight in the head i clean the head again and now its working normal with the original firmware.

And now back on vert his b483 Marlin 2 version i think is the best.

Hi,

I have the same issue but I don't understand what you mean. Could you post a picture of these "steel balls" please?

there for every filament tree imbus with behind a second imbus and there behind are the steelballs

Thank you for your reply.

I understand that what you call "imbus" is what I would call hex screw / Allen screw in my country.

I tried to unscrew the 1st "imbus", but I did not manage to make it turn at all.

I used the key provided by Geeetech. It seems to fit just right in it, but when I turn it slips inside. I feel that I am damaging the "imbus".

make the head hot with hair dryer or paint burner when you have the rest removed
sometimes then the get lose
