Hi everyone.

Previously I have create a project then i fabricate the pcb for the design. It is working well without any problem/short.

But then I created a new design with compress a bit the the space. I already run the DRC to check the cuircuit and it tell me there is no short on the design. But after i fabricate the pcb, my pcb become short. Can anyone help me to check the circuit explain to me what is going wrong with my second design?

Refer below my project file.

Where is the short? For me the sketch passes DRC, and there is no obvious short in the gerber output, it looks fine.

Can you mark the short on one of the images?

Sorry mister. I have found the short. I have joined the COM together with the copper pour. Which is I have created the copper pour for grounding.

I have fixed my design and hopefully no more short in the future.

Image is the shorted pin
