[Motion86]
説明
Set the software limit range for the machine motion.
Syntax
machine.config_PosLimit(axis, min, max);
Parameters
machine
: The machine object.axis
: The axis to set the limit of the software, AXIS_X, AXIS_Y or AXIS_Z.min
: Set the minimum position of the software for the axis, the unit depends on the PPU, usually is mm.max
: Set the maximum position of the software for the axis, the unit depends on the PPU, usually in mm.
Returns
- true: The setting was successful.
- false: The setting error means that the machine does not exist or was set up after the machine was started.
Please make sure that the machine exists and make sure that the machine is set up before starting the machine.
Example
Set the basic parameters of the machine and move the machine to the Home point.
