As of about April 2018, My I3X has been experiencing deadzoning issues. No matter the slicer (slic3r or CuraEngine) or the STL, the printer only allows me to print in the bottom left of the print bed (and it prints there fine). Is there any way to fix this?

Hi, mark
I think it's probably related to your bed dimension.

You can reinstall the firmware for a try.
Or, refer to this:
