Filament of E0 can't pass through & Disable Mixing

[krmmr]

Just got a new A20M and did 2 Prints. The Dog which was on the SD Card with the Mixing function which turned out quite cool.
Then i printed a Statue in a filament using E1.
Today i tried printing a lizard with two Colors (sliced using Cura). But the A20M always used the one Color i set the Mixing option to, for both colors. Cura sliced it fine and in Cura i can also see that both colors are used in the prepare tab.

When i changed the mixing on the printer itself to the other extruder, he printed all in that color.. how can i disable that mixing?

Also when i changed to the E0 i noticed that the filament can pass through the nozzle and nothing is getting print.. i know nozzles can clogg but on my other printer it clogged one time in a year.. after 2 prints a clogged nozzle..? How can i clean it up? i tried to remove the ptfe tube of the E0 Hotend Part but i wasnt able to get it out.. also after unscrewing the quick plug thing i was not able to get the tube out... any ideas?


Thanks everyone! i really dont want to send it back to amazon because of this.. already installt a 3dtouch and everyting working fine else..

Hi，if your hotend is blocked you can refer to this https://www.youtube.com/watch?v=uKxPIGal74E
and clean the nozzle.

Thanks will try that.. and what about my problem that the printer only prints what is set in the Mixer option on the printer and not what i define in Cura?
