  • Page 51 Part 4 Recommended Settings Key GRBL Settings $3 - Direction port invert mask If an axis is moving in the wrong direction, you need to change one of the settings, namely $3, the direction port invert mask to be precise. This is very easy to do.
  • Page 52 Part 4 Recommended Settings Key GRBL Settings $3 - Direction port invert mask Use the following table: Select the row for your current $3 value, go across to the column for the axis to change and the value there is your new $3 value. This only allows you to change one axis at a time. If you need to change more than one, make multiple passes through the process.
  • Page 53 Part 4 Recommended Settings Key GRBL Settings $100,$101,$102 - [X,Y,Z] steps/mm These parameters controlled the distance travelled by each axis. These values are the number of microsteps required to move the spindle on each axis by 1mm. $100 sets the X axis, $101 the Y axis, and $102 the Z axis. These should all be the same.
  • Page 54 $13=0 to set back to mm. We want to work in mm. So leave $13 at 0. You can check all the defined GRBL settings and what they mean using the link below: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration Note – changing GRBL settings beyond those mentioned above is not recommended by YoraHome, and is done at your own risk.
