    Has anyone else had this problem. I have built my first C-Beam machine using the Arduino Uno and the Adafruit Stepper Driver. I have made all my settings referencing the GRBL settings JPG provided on the Openbuilds C-Bean build section... i.e. step/mm =200. All works as expected except the Z axis. It is moving at twice the distance. I set the z step/mm=55 and that corrected the translation distance. Have I incorrectly configured something or has anyone else seen this issue. Also on another note, I am using Grbl Panel, and you are unable to change the Grbl settings and have it update the Arduino board (has to be accomplished using the Arduino terminal). Maybe this functionality only works with the CNC x-pro as shown in the tutorial video on the C-Beam build page.

    It sounds like the Z driver may have different microstep.

    Which Adafruit driver is it?

    Confirm the micro stepping.

    I had to adjust the grbl setting on my ox when I changed from 1/8 to 1/16 stepping.

    Thanks Teflon4, this is what I have..Synthetos gShield (grblShield) V5 and these are some of the specs..
    • 2.5 Amps per winding
    • 12-30 Input Voltage
    • Open Pin Pass Through
    • 8x Microstepping
    • Screw Down Terminal Voltage Input
    • Hardware 3x Axis (x,y,z)
    • 3x Robust TI DRV8818 Stepper Drivers
    This is all I could find, but I am not sure I can change anything on the Adafruit. Any recommendations appreciated.

    Chillimonster, I have not changed the stepping, at lease not intentional. I have set everything based on the image I posted. Now with that said I am not sure how I would change the stepping or micro-stepping. I am still learning. Thanks for the input.
