Question How to define custom printer?

[Claghorn 1]

My ancient and much modified solidoodle 2 homes X and Y to X max and Y max, not 0,0. X max also puts the print nozzle 8mm off the right side of the print bed.

 

I was interested in giving cura a try, but how the devil do I communicate this bed geometry to cura in a custom printer definition? My poor brain can't see any way to tell it something like this.

 

Update: Maybe my brain is better now. In RepetierHost, the manual controls try to inform me where the tip of the nozzle is at all times, so it needs to know the same things Marlin knows to be able to tell me. I think I finally understand that cura makes no attempt to do that, so as long as Marlin moves where cura tells it to go, all is well. I guess only Marlin needs to know where home leaves the nozzle.
