Ramps 1.4 board is it fried

Can I fix it.Started the printer the other day no movement of axis in repetier host , then I noticed the bed or the hot end were not warming up.

Hmmm , then I remembered repetier will not allow you the move the motors until everything has reached temperature.

So what next

Switched it all off and start with the power supply – on inspection there was a frayed positive lead and I suspect it must have been touching the negative lead.

Then I noticed the farmost left input + connection on the ramps was a little burned.

So now big time investigation.

So I guess the poly fuses need to rebuild themselves – in the meantime I will remake all of the cables to ensure nothing cannot touch anything it should not.

 

More to follow.
