Tree Journeyman with Dynapath Control

Hi All,
Been out of CNC machining for a while now, looking to get back into it again slowly. Just bought a Tree J425 with Dynapath Delta 20 control. Powered up this weeked and was able to home and zero machine after a couple of day's playing with it.I mainly program in EIA GCodes and looking for help on how to use fixture offsets. Also, I seem to loose program position whenever I shut machine off. Anyone in the Columbus Ohio area with Dynapath control?

You will loose position unless you use a fixture offset (E).

Underthetire, thanks for your response, it explains a lot. I will appreciate if anyone can post a simple Dynapath G Code program that uses a couple of (E) fixture offsets and has more than one tool. Thanks in advance all.
