    Motherboard issue

    in UltiMaker 3D printers

    More evidence

    Hi guys and gals, I’m hoping someone can give me some advice. One of my um2+’s has stopped powering up. After a close look at the motherboard a resister L1 seems to have blown (picture attached). I do get one green led on.

    Does anyone know if this can be replaced or is there a work around? Or do I need to rob a bank and replace the board. Any advice would be helpful. Thanks in advance.

    I used Cura to send some G-code to the printer to calculate E-steps. I found that after extruding 100mm in extruded exactly half (50mm)

    So I set the E-steps value to 738 double the preset value and the filament now looks like it will move the entire length of the bowden tube but the motor seems to be having issues. It makes a whirring sound and the filament skips as its being moved up the tube. I vaguely read somewhere about the motor settings needing changing after the e-steps value being altered but I can't for the life of me find it again.

    Yes the correct firmware was used. I thought a long the same lines with the feeder possibly being the issue but I fitted it to another machine running stock firmware and all seems to be working fine. Its very confusing. I've even tried a new motor to see if that was the problem but always the same outcome. Thank you for your help though
