    Default Current set resistor

    I just want to run this by the experts here, i have 4.2 amp steppers an 80 volt power supply and G203 drives, by my calculation I need a 70k 1/4 watt resistor for each drive, Does that sound correct?

    Ran the calculation and came up with 70.5K

    It also falls within the values listed in the manual

    g. 4A – 62.67K
    h. 4.5A – 84.6K
