Manual Accuation of Z Probe

I have a custom delta printer that I have spend the last three months building. It is a delta type and I am using the latest version of Marlin. I have it calibrated and ready to go but after having many failed calibration prints I would like to attach a z probe to the printer. I printed this from thingiverse on a friends printer and was wondering if Marlin can do auto leveling with a manually acccuated z probe?

I was just thinking and would it work to have this be my start gcode in slic3r?

g28 ; Home all axis
g4 p10000 ; Gives me ten seconds to attach the z probe
g29 ; Auto-Level
g4 p10000 ; Gives me ten seconds to remove the z probe
; start print

Now if I am thinking of this logically will I have to add some code to make the nozzle go down all the way. Because of the offset by the probe?

Might work but use capital letters in start and end gcode or the commands won't execute, host programs capitalise automatically to save you keystrokes.

There is a gcode for wait for User, so you attach probe then hit encoder button to continue, then same again when removing, might be less exciting than having a timeout.

Bah that's way less fun. More fun to have a matter of seconds to perform fine motor function things right next to 240 metal object before your hotend smashes through your bed!

You're right we need more danger it's more fun.

Even though waiting for the user would be a safe idea part of me wants to wire in a big red 7-segment display that shows a count down winking smiley
