[transorsmth]

Is your feature request related to a problem? Please describe. When adding the BedLevelVisualizer start gcode to the start print gcode, the bed levels, but it never triggers the visualization.

Describe the solution you'd like Make an option so bed level visualizer is triggered if @ BEDLEVELVISUALIZER is sent, even if the button isn't pressed.
