I'm Trying to get back into using Simplify3D since V5 release, I have a modified Ender 3 Max running Jyers Firmware. The first thing I did was print a bed centering STL file which showed my prints were not centered within the print bed. I changed my Global Offsets X and Y settings to center the bed perfectly in the middle of the build plate.
Then I moved on to Teaching Techs First Layer Test STL file. When this is being printed and I moved the offset mainly in the Y direction the two top-left and top-right first layer blocks hit a hard stop even thought there is enough room to print the brim and square. The printer acts like its at the end of the build plate and prints over itself. Pictures are attached.
Answer: In the firmware notes for Jyers Firmware it said to use Gcode: M211 S0 to disable software endstops
