ABL w/ the Rumba Board

[jasay]

I'll be honest... I could do without the ABL and just have an adjustible offset when homing for Z and i would be gloriously happy... because if the glass is level then abl isnt needed and a number to adjust closeness to the bed makes life so much easier than turning a screw

I don't have ABL, but like you wish I could auto adjust the initial offset. Could you change this line in Marlin to "1"?
