[Motion86]
Description
Returns the Machine to the home point.
If config_HomePins is configured, the machine moves in the negative direction of x, y, and z axes until it touches the limit switch and sets that position as the home point.
If config_HomePins is not configured, the machine will take the current position as home point.
Syntax
machine.home();
Parameters
Machine
: Machine object.
No parameter.
Returns
None.
Example
Set the basic parameters of the machine and move the machine to the Home point.
