    HI,

    Im looking to set the micro-stepping on the rumba. Is this done via the

    ON/OFF
    1 2 3

    switches under the driver?

    If so, which number represents which step fraction┬┐

    Cheers

    You are right. Every driver slot has 3 switches/jumpers (under the plugged driver)

    1/2/3 represents

    MS0/MS1/MS2 (ModeSelect pins of the driver IC)

    just from left to right.

    To find out which setting is required for your drivers you just have to look in the datasheet of the driver IC.

    E.g. for DRV8825 : http://www.ti.com/lit/ds/slvsa73d/slvsa73d.pdf you find a table of the settings on page 10.
