Hi. I've just bought UM2C, and I have some troubles testing the printer

First, It often makes rough corners. (layers don't bond well)

Second, I tried some overhang angle test, but quality is kinda sus

 

Here are some pictures about these problems..

 

I tried changing nozzle and heatbed temperature, print speed, and etc... But these troubles still remains

Please help me..🥺 Thanks.
