The D Series Laser Machine Stops Mid-Job

This article applies to:

D1 and D1 Pro with all laser modules.

 

Issue Description

When you use an xTool D1 or D1 Pro laser machine to laser engrave or cut, you may see the machine suddenly stop working in the middle of a job. In addition, you may see one of the following responses from the XCS software.

 

• The pop-up window shows that the device is still processing.
• A pop-up window shows that the device has been disconnected.
• A pop-up window shows complete.

 

In this guide, we will provide troubleshooting steps case-by-case. Please refer to the instructions according to XCS response to solve the issue, and if needed, collect diagnostic info and contact customer support for further advice.

Note: Please avoid turning on or off high-power electrical appliances to avoid circuit fluctuations leading to the suspension.

 

If XCS Remains at the Processing Screen

In this case, you will see this processing screen below on the XCS software even if the machine has already stopped mid-job. This usually happens when the USB connection is used.

 

#1 Check the Connection Method

The computer sends the data to the machine bit-by-bit in real time under the USB connection mode. If your computer is not fast enough, data conflicts may occur during the transfer, causing processing to stop.

 

1. Check if you are using the USB connection mode.
2. Use the Wi-Fi connection mode instead and try again.
3. Move on to the next step if the issue persists.

 

Note: If you use the Wi-Fi connection mode, the entire data will be sent to the machine before the processing starts, avoiding any data disruption. XCS supports both USB and Wi-Fi while Lightburn supports only USB.

 

#2 Check the Computer Configuration

Make sure your computer configuration meets the following requirements.

Hardware	Minimum Configurations	Recommended Configurations
Processor	Intel Core i5-6200U	Intel Core i5-11600 or higher
Operation System	Win10 64-bit Mac 10.14	Mac 10.15 or higher
RAM	8GB	16GB or higher
Display Resolution	1280*720	1920 x 1080 or above
Hard Drive Storage	8GB	12GB or above

 

Note: Please collect the diagnostic info listed in this guide and contact customer support for further advice should the above instructions not solve the issue. Especially for this info:

• The XCS software's version.
• The machine's firmware version.
• The log file of the processing.

If XCS Shows 'The Device Has Been Disconnected'

In this case, you will see the pop-up window showing that "The device has been disconnected" below on XCS software.

You will also see a blink of the blue indicator at the edge of the motherboard blink, which means it's rebooted.

This could be the case regardless of the USB or Wi-Fi connection method, as long as any of the power adaptor, the motherboard, and the laser module is faulty. So we will need to check each of them in the following steps.

 

#1 Check the Laser Module

1. Unplug the laser module connection cable to disconnect it from the machine.
2. Try with the same project file and see if this time it can complete the run.
3. If it can, the laser module could be short-circuited. It needs to be replaced.
4. If it still can't, please move on to the next step.
   

 

Note: To second confirm if the laser module is short-circuited, do the following:

1. Get a multimeter and set it to buzzer mode.
2. Place the needle probes on the GND and PWM pins on the laser module.
3. If the buzzer goes off, the laser module is short-circuited.

 

 

 

 

#2 Check the Motherboard

After the laser module is ruled out, check the motherboard.

1. Check the status of the blue indicator on the board.
2. If the indicator blinks, the motherboard is faulty. It needs to be replaced.
3. If the indicator stays solid, move on to the next step.

 

#3 Check the Power Adaptor

After the laser module and motherboard are ruled out, check the power adaptor.

1. Check the status of the green indicator on the adaptor.
2. If the indicator blinks, the adaptor is faulty. It needs to be replaced.
3. If the indicator stays solid, move on to the next step.

 

#4 Check the Software Operation

Note: Please avoid additional operations on XCS during the process, otherwise XCS may be disconnected.

1. Make sure you don't run Lightburn software when XCS USE Wi-Fi connection.
2. Make sure you don't change the device on XCS during processing.
3. Make sure you don't minimize the XCS interface during processing.
4. Make sure you don't press the buttons on XCS during processing.

 

#5 Check the USB Cable Connection

1. Make sure the cable is connected properly at both ends.
2. Make sure the cable is intact. Try another cable and see if it works.

#6 Check Other Appliance Connection

We do not recommend that you connect your laser machine and other high-power electrical appliances to the same circuit. It may lead to a large current and unstable power input. If you have already done so, please avoid turning on or off those appliances. If the issue persists, disconnect the high-power appliances and try again.

 

If all the above methods don't work, feel free to contact our support team if you have any questions

If XCS Shows ‘Complete’

In this case, you will see that XCS says "Complete" even if the machine stops mid-job (as shown below). This usually happens on the TF card or Wi-Fi processing mode.

#1 Check the TF Card

1. Turn off the machine and replug the TF card.
2. Turn on the machine again and see if it works.

 

#2 Check the Wi-Fi Environment

1. Try with a different Wi-Fi connection.
2. Try with a portable hotspot and see if it works.
