Neje Max4 X axis keeps shifting left while engraving

My Neje Max4 recently started shifting left during engraving. It starts out fine but after a few MMz up the Y axis it will shift left. It does this several times during the engraving. When it finishes and goes to the lower left it hits and I can’t get it to go home, without going to the move window and moving it right a few MMs.
