This article applies to:

S1 with all laser modules.

Issue Description

If S1 won't power on, please follow the instructions below to troubleshoot.

Solution

#1 Reset the emergency stop switch

When the emergency stop switch is pressed, the machine will be disconnected from the power supply.

If it is pressed, please turn it clockwise to reset it.

The emergency stop switch is pressed.	The emergency stop switch is reset.

#2 Check the SD Card

When the SD card is faulty, the indicator on the main control board will be on. But the LED strip on the front and rear plate, and the red cross light of the laser module will be off. This may appear as if the machine is not powered on.

Try the following to determine if the SD card has to do with it:

1. Take off the SD card and see if the machine is back to normal.
2. Put it back into the machine and see if the machine gets non-responsive again.
3. If so, the SD card is causing the issue and may need to be replaced.

Additionally, if you'd like to dig into the SD card, here are something you can try:

1. Check the appearance of the SD card.

• See if the card is in good shape.
• See if the pins are deformed.

2. Get a multimeter and switch it to buzz mode.
3. Get the probes and test the two pins shown in the photo.
4. If the buzz goes off, the SD card is likely to be short-circuit.

Note:

• The SD card needs to be in FAT32 format and less than 32G.
• Third-party cards are not tested and may not be compatible with the machine.
• It's recommended to contact support@xtool.com for the card replacement.
• You can replace the SD card according to the video tutorial:

#3 Check the Power Adapter

Inspect the status of the power adapter's indicator light and follow the instructions below accordingly to settle the issue:

Adapter Indicator Light Flashing:

• Disconnect the adapter from the S1. 
  • If the adapter light continues to flash, it indicates the adapter is malfunctioning. Replace it to resolve the issue. Please contact xTool Customer Service for a replacement.
  • If the adapter light stops flashing after disconnecting it from the machine but starts flashing again when reconnected, it suggests the presence of a short circuit in the main control board. Contact xTool Customer Service with these troubleshooting results for further assistance.

Adapter Indicator Light On:

• Observe whether the power indicator light on the adapter is on and solid.
• If a multimeter is at hand, set it to DC voltage mode to check if the output voltage is within the acceptable range (25V). 
  • If the voltage is not within the acceptable range, it denotes the adapter is malfunctioning. Replace it to resolve the issue. Please contact xTool Customer Service for a replacement.

#4 Check the Main Control Board

The Control Board Resistor

• In some cases, the resistor on the control board may fall off during transportation.
• Please check if the black resistor circled in the photo is missing.
• If yes, the main control board needs to be replaced.

The Voltage Readings (1)

1. Connect the power adapter to the main control board.
2. Turn on the main control board.
3. Switch the multimeter to AC voltage mode.
4. Put the probes on the pins pointed out in the photo below.
5. Check if the voltage reading is around 3.2V~3.3V.
6. If not, the main control board is faulty and needs to be replaced.

Note: The control board has a layer of conformal coating, which may affect the readings of the multimeter. Please make sure the probes are in contact with the pins properly for accurate results.

The Voltage Readings (2)

1. Switch the multimeter to buzz mode.
2. Put the probes on the pins pointed out in the photo below.
3. If the multimeter buzzes, the main control board has a short circuit and needs to be replaced.
