I'm checking out my new R7, using Sketchup with SketchUCam to Chilipeppr to TinyG. X axis is positive towards the right (from front of spindle). Using Sharpie & posterboard, all my output is mirrored. I didn't notice it at first until I did text. Output looks great in a mirror. It feels like I need to change the X axis motor rotation. I assume this should be simple in software - but I'm overwhelmed with all the gcode options to know where to start. Any solutions would be greatly appreciated.
