Greetings,
Loaded gcode displays inverted. When the image is rotated, and following the X/Y/Z legend in the lower left when the Z is pointing down the zdown comes up from the bottom, and alternately, when the Z is pointing up the zdown comes down from above. 0,0 is overtop of the lower left extream of the table, however the axis don't seem to correspond, but seem to be backwards of what actually occurs.
