Clog after clog

Hey guys maybe you can give me a hand. So first I have to say this is my first filament printer. I am very green and learning as I go. I must add I bought the combo.

​

I first tried printing with the stock head. I believe .2mm if I'm correct and it printed the benchy perfect. Then I tried to print something else and clog. I believe that may have been my fault because I didn't enter in the correct filament type. Then I learned.

​

Ordered some new heads. Ordered .8 heads and printed asa with petg supports. Entered everything in correctly. I believe. When it was switching from asa to petg it clogged again.

​

So this time I tried printing something different. I swapped out the head again to another .8mm head and used petg with petg support. Punched everything in correctly. Double checked and another clog.

​

I'm not sure what I'm doing wrong or what is happening. Any help would be greatly appreciated.

​

Thanks guys!
