Asynchronous z-axis

[TheGuv]

Visicut enables the z-axis to be set at the start of each job which would allow optimum focus to be set according to the thickness of the material being lasered.

Unfortunately the 'move z-axis' (SimpleCode 2) command is designed to be asynchronous. This means that the job starts cutting while the table is still being moved and still a long way from being in focus.

This command should be made synchronous so that the Z move is complete before the job starts being lasered.
