Don't know if there is already some way to do this that I'm missing, but it would be useful to have a "Home Z" button in the bed leveling wizard. The way I level (on a Makergear M2) is to move the nozzle around to presets in the wizard, then home Z at each preset and adjust the leveling screws accordingly. I have to home Z because the bed level wizard always drops the bed about 10 mm before moving to the next position, and it does not raise it up again. I like this method because it both levels the bed and sets the z-height at the same time.
So I have to have both the bed level wizard and the Machine Control panel open and accessible at the same time. Not a huge problem but the only way I've found to do it on a Win 7 laptop is to force the main window to the right half of the screen (win + left arrow) and then have the control panel open on the left. Be nice just to have the Home Z button right next to the Next Position button (or whatever it's called) in the bed level wizard.
