    Hello,
    I’m using the 6 axis CNC Demo Rumba Arduino code currently connected to three (for testing purposes/have not set up the other motors yet) NEMA 34 motors controlled by DM860A Mircosteppers and an Arduino Mega. I can get the motors to move, but I am unable to control the feedrate using G1. I have tried various set ups and different codes to no avail.
    I’m currently imputing the code ‘G1 F5 X1200 Y1200 Z1200’ and all the motors move, when I change the feedrate nothing happens. I would like it to move very slow.
    Thanks for the help

    I have no experience with such low feed rates. If you set the feed rate

    G1 F5

    and then ask for the current feedrate

    M114

    Does it say feedrate=5? What is the minimum feedrate allowed in your firmware?
