so i wired everything up and checked the endstops. it looks kinda good i guess.
After i pressed HOME ALL, the axes did what they were supposed to.
I want to thank all three of you guys for staying up this late and helping me figure this out and also for not giving up when i had no idea what could be done otherwise.
cheers lads and thanks so much.
the port is perfectly fine, the board just doesnt reply to my messages, makes me sad 
I installed pronterface and im not familiar with it at all
thanks for the help guys.

well alright.. ill wait.
should i do anything else or just wait here?
where should i request for one ?
I understand your concern, but the problem here is that right now i have a lot of free time and i want to put it to good use to build out my custom printer, however this small accident ruined the entire board and i cant get anything done. Im not saying that i dont care about the environment and all, but i just need this board fixed so i can get up and running again.. and because i dont have the expertise to fix it, and now is not the best time to sent the board to other people in the community because of the situation we have in the world, i am comfortable with sending it back to duet.
Is there any way i can maybe get a replacement?
I will consider sending it to someone for repairs.
does duet themselves not repair boards? dont they have a repair service?
there is a short between 3,3 and gnd, the green led doesnt light up, when i apply voltage from usb and no other component gets hot.
no other component gets hot... it was only the regulator, if the others dont get hot then how am i supposed to know which one i must remove?
I have no experience troubleshooting or fixing these boards nor do i have any smd rework tools.
can i send them to duet for repair?
because im not comfortable with removing and adding components, im afraid i might cause more damage than there is.
is there anything else i can try?
as soon as the vcc crimp of the sensor hit the hotend, the printer disconected.
the crimp didnt stay on the hotend, it just made contact for less a second and fell away from it.
i removed the sd card and the green led doesnt light up.
no other component gets hot.
the 3,3v regulator U2, i have cut the 3,3v pin to solder an external power source but when i measured between gnd and the pin, it was shorted and my external source got super hot, so i removed that.
