4 axis help please

My 4 axis foam cutter is build and everything seems to be in working order, at least with CeNeCe in windozzz.

I've been reading posts and manuals to the point of confusion, are there someone who could please help me step for step to get my EMC set up for 4 axis foam cutting?

Thank you for you're reply. I liked the link, great idea. Unfortunately I am not much wiser. I've got a linear machine. I think the way of getting somewhere is (1) to use stepconfig and create the a axis configuration. (2) Change the .ini and .hal files so that I have 4 linear axis and not 3 liniars with one rotary. I've tried but stil no results.
