Machine.setHomeSpeed()

[Motion86]

Description

Set the feed rate for the machine to return to the Home point.

Syntax

machine.setHomeSpeed(feedrate);
machine.setHomeSpeed(xFeedrate, yFeedrate, zFeedrate)

Parameters

  • machine: for Machine object.
  • feedrate: A single parameter that sets the speed of x, y, and z axes of the machine to return to the Home point as feedrate.
  • xFeedrate, yFeedrate, zFeedrate: set the speed of x, y, and z axes to return to the Home point respectively.

Returns

None.

Example

Set the basic parameters of the machine and move the machine to the Home point.

#include "Motion86.h"
 
// Generate machine objects, up to machine 0~2 three machines, each machine has three axes. 
Machine machine(0);
// Stepper motor enable pin.
int EnablePin = 4;
 
void setup() {
 
  while (!Serial);
  pinMode(EnablePin, OUTPUT);
  // If necessary, you can reverse the motion direction of the motion axis.
  machine.config_ReverseDirection(AXIS_X);
  machine.config_ReverseDirection(AXIS_Y);
  // PPU (pulse per unit) is a virtual length unit, depending on different requirements.
  // In this example, the unit length of x-axis is set to 80 pulses, which corresponds to 1 mm in real application.
  machine.config_PPU(AXIS_X, 80.0);
  machine.config_PPU(AXIS_Y, 80.0);
  machine.config_PPU(AXIS_Z, 1600.0);
  // Set the software limit for the machine motion.
  machine.config_PosLimit(AXIS_X, 0, 300);
  machine.config_PosLimit(AXIS_Y, 0, 200);
  machine.config_PosLimit(AXIS_Z, 0, 300);
  // Set the pin used to set the limit switch for the home point.
  machine.config_HomePins(2, 7, 8);
  // Before controlling, the machine must be started.
  machine.machineOn();
  // Set the default feed rate.
  machine.setDefaultFeedrate(400);
  // Start the software limit.
  machine.enableSoftLimit();
  // Set the feed rate to return to home.
  machine.setHomeSpeed(1000, 1000, 200);
  // Start the stepper motor.
  digitalWrite(EnablePin, LOW);
  // Return to the home point defined by the limit switch.
  machine.home();
 
home(); }
 
void loop() {
  // Motion control code...
