Looks like RC3 has a different marlin_main.ccp

ABL question.

I have RC3 up and running. Is there a way to store ABL to EEPROM and have it recalled for the print?

With pronterface G28 note z position then bump your z down to your nozzle clearance not the z position subtract from probe and that's the offset

Thanks.. ..

So here is my Cura start I just add G29 after the G28?

;Sliced at: {day} {date} {time}
;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}
;Print time:...

Question how do I execute the command to auto bed level at the start of a print using Cura. Sorry im not a coder and some of the basics escapes me.
