My calibration cube comes out as a rectangle, so I went to calibration.h via Arduino and note x and y steps are not independent, if I change the value for xy steps and press upload, how do I know if it really uploaded? I run Pronterface and the cube still comes out the same dimensions even after several variations of trying to change the firmware. Obviously not uploading right. I saw that someone else had a similar problem but haven't found it again
thanks!
