Machine.getPPU()

[Motion86]

描述

Get the PPU value of the machine in the specified axis.

The relationship of PPU (Pulse per Unit) is as follows.

86Duino sends a pulse to the stepper motor driver board, which sends a step to rotate the stepper motor.

• micro_stepping
  The number of pulses received from the 86Duino to type a step on the stepper motor driver board.
• steps_per_revolution
  The parameter on the stepper motor, the number of steps to be received from the stepper motor driver board to make one revolution.

The formula for pulses_per_revolution is steps_per_revolution * micro_stepping.

• PPU: The number of pulses required to move the machine axis per unit distance. e.g. 80 pulses/mm.

語法

machine.getPPU(axis);

參數

• machine: is the Machine object.
• axis: is the motion axis of the PPU, it can be AXIS_X, AXIS_Y or AXIS_Z.

回傳

double: Return the PPU value of the motion axis.
