@jeff Hi, jeff. I see the filament stick on the nozzle in the first picture? Is the filament leak our from the gap between the nozzle and heat block? Could you please clean the nozzle and then check this?

I am also wondering if you put the right direction, you should put the rotary knob on the build plate and the gear side on the top. You do not need to add support in this way. It looks like that you put the gear side on the build plate, it makes the contact area too small in this way.

I did clean the nozzle off after seeing that.

That got me more results like the 3rd image.

This I don't understand, because I am not familiar with all of those terms.

What do you mean by "rotary knob". "build plate" and "gear side"?

@jeff I am meaning when you slice this model, you have to put the knob side on the bottom, and the gear side on the top. Because the 3rd picture seems you put the gear side on the bed that makes the adhesion is not enough.

thx for this info
