    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.

    Here we go again

     

    Poly fuses seem to have recovered , all cables re-done , applied power – ran up repetier – hot end and bed still not heating up – more investigation required.

    So How to check the motor side ?

    Give the arduino a new sketch to check the motors , done that , reset the arduino and all the motors kick into life.

    So now the problem is the +- on the left hand side that distributes power to D8,D9,D10 – – q1,q2 look fine q3 looks discolored so next job is to test them.

    But’s that is for another day.
