I have been using Simplify 3D for over 5 years with no problems. I am using a MendelMax 1.5 printer. Just recently, it will no longer print the full width of the print bed. Y and Z axis are fine, but the X axis is not. It stops about 25 mm short of going all of the way across the bed. I have reset the printer many times and even tried to change the width of the print bed many times. Nothing seems to help. I have made changes to the width in both the Gcode and the options sections of the program. I am at my wits end trying to figure this out.....any help will be greatly appreciated.
