I usually only cut 3d with my Multicam MT22, but today i had a DXF file up for running. When i cut 3D files i have to make certain the gcode has -Z for going down into the material and positive Z for lift over the material..
To my suprise, when i loaded the gcode for the 2D cut it was completely oposit i had to change values to positive instead of negative values for it to go down into the material.

Is this normal ? is the Z axis only reversed when cutting 3d not 2d?
