There is a long standing bug in MBI's firmware. The bug and fix was reported to MBI but they've chosen to not fix it. It is fixed in Sailfish which is why upgrading to Sailfish solves the issue. Alternatively, you can comment out all the M70, M71, and M72 gcode commands and thus avoid triggering the bug.
For more information on Sailfish, see
Installation and setup directions are hosted by MBI at
And note that MBI does support bots running Sailfish.
