Screw Tilt Adjust

[Tordan004]

First of all a big thanks to everyone involved in developing the helper script. It helped me a lot! In order to make it a bit better I thought I'd give you some feedback on a problem I faced and possibly ask for a correction concerning screw-tilt-adjust. When running this the parking position over the back left screw is too close to the heat bed in order to get a key into the screw when adjusting the height. I therefore propose that either the height is being set by a parameter that can be changed or possibly raise the position from 5 to say 40 in order to get to the screw.
