3D Printer Help

Hi !
I’m a Mechanical Engineer from India. I’ve developed a i3 style 3D printer at home, during the covid lockdown, in India.
Managed to calibrate the printer and all the parts are looking good to me. But somehow the benchy is having problem to print on my printer. I want to know of it’s a hardware problem or my slicing inexperience.
Could really use your help to develop my printer further !
(The printer is made using locally sourced parts and scrap metal. )

Have been following your channel since last year.

Please please please help me!

Slow down the print especially in small layer, also part fan cooling should help too.
