This is my temporary workaround, just installed it a few days ago. I have two fences, one set at the limits the X and Y axis, cut with the machine itself, and another temporary fence system with the touch probe clamped to a block which also gives me the workpiece x/y 0.
I work with x/y offsets in Vcarve or create an artificial spoilboard in my CAD software, with the workpiece offset. Of course it could be more elegant, but seems to work perfectly fine.
