how to set z-height bevore print
-------------
1. heat everything to print temp
2. run this script (best to include in slicer start script):
	G28 ; home
	G1 X0 Y0 Z10 F5000 ; center everything 10mm above bed
	G30 ; probe bed, set height
	g1 Z5 ; hover 5mm over bed

	DONT'T HOME!!!! Because then the height will be DELETED!
	to adjust the height change
	G31 X0 Y0 Z-0.6 ;
	then run M500 to save it in config-override!!!
