On my Airwolf XL printer is doing something weird when I try to print. The picture is of what is supposed to be a calibration square, as you can see it looks more like a set of stairs. Have tried using different print file, different printing software, re-uploading firmware, different print files and everything else I can think of with no results. Contactred both AIrwolf3d and Ultimaker (manufacturer of the Rambo board) and neither were able to help. As with so many printer issues it is most likely something simple but I cannot for the life of me figure it out. ANy help would be greatly appreciated.
