I've got a 2 pole 15A breaker in my existing panel with wiring to a laminate machine only. I've added additional 2 outlets, light & light switch with 14/2 wiring to the same breaker and my light and any plug in keep popping. What am I doing wrong ?

Double pole breaker if for 240 volts. Get a single pole 15 amp breaker for lights and outlets and receptacles. Black to breaker and white to neutral/ground bar.

Like HK said, you wired regular 120v lights and receptacles to 240v. This is pretty basic stuff and you unfortunately learned the hard way that there is a very real difference between 120v and 240v.

Or did you only use half the two-pole breaker to get 120v? From your description it sounds like the former.

What is the draw of the laminate machine? Even though you say "only" the laminate machine is on the circuit many of them are a very big draw.

I'll change to a 15A breaker.

U could change to 2 mini breakers and have a free space for future use or divide new circuits between them.

Good luck

Thanks to all.

I don't need the 240v anymore for the laminate machine. It has been removed.
