I burned Arduino on ramps 1.6 - Dunno why... February 06, 2022 05:21AM |
I am doing my 3D printer project.
i wanted to set on my 3d printer bl-touch. i short vcc 5v with jumper on mega 1.6. The board turned off immediately and my arduino just burned in 3 sec.
Can someone explain what I did wrong ?

There must be a short on the 5v servo rail somewhere.
check resistance from 5v pin to gnd
I checked the resistance and it is 0 zero .
Seems like something is wrong right?
What could it be?

that is very wrong
the 5v pin should only connect to 5v pins on servo plug
There is either a pcb fault, for a solder bridge somewhere.
Finding it will be nearly impossible
Thanks for info. is somewere avalable Ramps 1.6 PCB DESIGN ? i wanna follow where is 5V trace going...

i did already (24v) by mistake. but... i just burn only arduinoQuote

... if it's onla a "small" short, you can try to locate it by high "overcurrent" -- maybe it will burn/explode the short, so you can see where ...

... then good luck with finding the error ... or, better find a different board

ok so it is not gnded there.. was just the picture.
If this was my board, I would cut the track on the red line as pictured
Then test which side has the short to gnd, Either the +5v pin on the servo plug end or just the vcc/5v jumper end.
give you an idea where to look.
If short is not on the servo plugs side I would just ignore it. (apart from curiosity)
then all you need to do is connect +5v on the servo plug to any vcc nearby with a jumper wire.
If the short is on the servo end... next step would be to un solder the servo pins and examine what is on the top of the pcb under the where the pins where

i am planing to unsolder everything as possible.
i will post new images later.
thank for helping and advice..

I desoldered the whole board and its sanded now .
and i think i found why 5V and Ground have shorts..
I think there is a short where I highlighted.

Over kill, but nice!
Yes that looks like the short to me. and a bad one.
Cutting the track like I suggested should work, or drill out that via.
I cut already this track on this board and everything is okay.

Can I use your images?, ill add a note to the reprap wiki about this issue
yes! no problem
