Issue Description

When this issue occurs, the laser head won't go back to the home position properly.
You may see the X-axis gantry keeps crashing into the structure of the machine or simply won't move on the Y-axis.

If the machine is connected with XCS in the meantime, you may see a pop-up notification like below.

 

#1 Check the X-Axis Gantry

  1. If the X-axis gantry is not aligned, the Y-axis limit switch can't detect the limit piece.
  2. Push the X-axis gantry towards the rear plate until it touches it.
  3. Then Push it hard against the rear plate so that both ends are aligned.

#2 Check the Installation of the Port and the Sensor

Note: The Y-axis limit switch is in the right corner of the machine near the rear plate.
  • Unplug and replug the cable to make sure it is fitted properly.
  • Check the black sensor probes for deformation. If it's deformed, please straighten it.

#3 Check the Y-Axis Limit Switch

Note: The Y-axis limit switch is in the right corner of the machine near the rear plate.
  1. Manually move the gantry towards the front plate.
  2. Insert a black material into the gap between the two sensor probes as shown below, and observe whether the indicator of the Y-axis homing signal changes.
  • If it does not change, it indicates the switch is faulty and needs to be replaced.
  • If it changes, it means the switch functions properly. Please move on to the next steps.
 

#4 Check the Cable or the Motor

  1. Restart P2 and connect it through USB.
  2. Open your browser, input the provided links in the address bar, and hit enter. Observe if you can effectively control the movement of the laser head after the browser returns "OK".
  3. If you can not control the laser head as expected, the cable of the motor or the motor itself might be faulty and should be replaced.
 

If None of the Above Works

If the issue persists, please collect the work log, a picture of the Serial Number sticker on the machine, and the video about the issue, and contact xTool tech support for further advice at: support@xtool.com
