$3 - Direction port invert mask
2/2
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.
Examples:
- Current $3 value is 2 and the X axis needs inverting: Select the 2 row and the X column, the new $3 value is 6.
- Current $3 value is 3, and the Y and Z axes need inverting: To invert the Y axis, select the 3 row and the Y
column, the new $3 value is 1. To invert the Z axis, select the 1 row and the Z column, the new $3 value is 0.
In Easel, type $3=x in the console command box
where x is the revised number and hit enter to send it
to the route motherboard. Everything should now be
moving in the correct direction. If you changed any
settings, make a note in your file containing your
original settings just in case.
