Homing Introduction

Movement Direction

• Description of XY motor control inversion and incorrect movement direction for the COREXY structure

Case	Phenomenon Description	Hardware Solution
Case 1	XY axes control each other, and both positive and negative movement directions of XY are reversed	Reverse the wiring of the X motor (swap any two phases of the X motor)
Case 2	XY axes control each other, but both positive and negative movement directions of XY are correct	Reverse the wiring of the Y motor (swap any two phases of the Y motor)
Case 3	XY axes control each other, X positive and negative directions are correct, Y positive and negative directions are reversed	First reverse the X motor wiring, then swap the X and Y motor wires entirely
Case 4	XY axes control each other, X positive and negative directions are reversed, Y positive and negative directions are correct	First reverse the Y motor wiring, then swap the X and Y motor wires entirely
Case 5	XY axes control is correct, but both positive and negative directions of XY are reversed	Reverse both X and Y motor wirings simultaneously
Case 6	XY axes control is correct, X positive and negative directions are correct, Y positive and negative directions are reversed	Swap the X and Y motor wires entirely
Case 7	XY axes control is correct, X positive and negative directions are reversed, Y positive and negative directions are correct	First swap the X and Y motor wires entirely, then reverse both X and Y motor wirings simultaneously

Homing Instructions

Step 1: Check Endstop Status

1. Move the print head to the center of the heated bed.
2. Enter the following command in the console:

   QUERY_ENDSTOPS

3. Check the returned endstop status:

• All endstops should display OPEN under normal conditions (indicating untriggered status).
• If TRIGGERED is displayed, it means the endstop is already triggered. Do not modify the configuration yet; proceed to the next step first.

Step 2: Manually Trigger Endstop and Check Status Changes

• Manually hold down a specific endstop switch, then enter QUERY_ENDSTOPS again in the console to determine the endstop switch's working condition. The details are as follows:

Status Change	Meaning	Possible Cause or Recommendation
From OPEN to TRIGGERED	Endstop configured correctly	Switch and wiring are normal, configuration is correct
From TRIGGERED to OPEN	Endstop signal inverted	Signal logic in the configuration is incorrect; reverse the endstop state
No status change	Endstop not responding	Pin configuration error, wiring disconnected, or switch damaged; hardware needs inspection
Other endstop statuses change	False triggering	Pin configuration conflict or wiring error; configuration and wiring need inspection

Multi-Axis Movement Method

Configuration Steps

1. Add the following configuration in printer.cfg to enable the force move feature:

   [force_move]
   enable_force_move: true

2. You can perform force move operations through the control interface (as shown below):
   

Notes

• Single Motor Movement: Only one motor can be moved at a time, even if the machine has a multi-axis structure.
• Multi-Axis Synchronized Movement: If multiple axes need to be moved simultaneously (e.g., dual Z axes), set the print head position using the following command before executing the movement:

  SET_KINEMATIC_POSITION x=50 y=50 z=20
