    Meus motores aquecem muito, uso DRV8825 NEMA 1.5a, Conf. o vref 1.05a 70% (0,55 xy e dobrado 0,77 no Z, esquenta muito, nao consigo colocar a mao nos motores ???? HELP

    I recently went through this process on my Maker Select v2. The formula used was current (amps) x 8 x sense resistor value (.1). Then that number was multiplied by .9 to get 90% power. I'm setting my Voron 2.1 up now (using the recommended 2a stepperonline motors w/ 4988 drivers (sense resistor r100) and was wondering if the 1.4 vref value I got would do the trick?

      On Voron 2.1 and preferred motors (from official BoM) you need only 1.2-1.4A on 12v and near 0.9A for 24v.

    If you cant measure voltage with a Arduino uno CNC shield, your Arduino needs to be powered on... Just in case this helps somebody, that was my issue.

    input voltage 24 volt.
    Vreferenc is depend on voltage..?

      input voltage does not affect setting your drivers Vref

    Does klipper need to be pre installed on the Mega?

    • @CanuckCreator

      No. No software installed on the controller is required to set the vref this way

    I saw another video saying you want to make sure the motor connected to board as well before powering the board or you can fry the drivers.
    That was for an Arduino CNC shield and DRV8825 drivers though. ua-cam.com/video/OfyT1xTZC6o/v-deo.html
