Sculpfun S30 Pro Max, connected to the TS1 module, randomly stops, while the laser remains on, during operation

Good day. I’m having a problem with one of my Sculpfun S30 Pro Max 20W lasers (I have two). It randomly stops working occasionally, with the laser on. The X and Y locations of the stops, when they happen, are also always random. This suggests that it’s not the generated G-code.

I’m using it connected to the Sculpfun TS1 module. The firmware is the latest version (1.1.32). Version 1.1.31 also had the same problem.

  • The motherboard is model XY-DLC32-QH v1.2A, also with the latest firmware version.
  • The USB cable is shielded and short.
  • The machine is lubricated.
  • The SD card is not corrupted. I always save the G-codes first on the computer and then copy them to the card. I don’t overwrite files. I use short names without special characters.
  • The power supply is original and stable.

I’ve already tried all the recommended solutions, but it continues to have these interruptions from time to time.

The other one, after I updated the firmware, stopped having this problem, but it has a different motherboard model (XY-DLC32-MC v1.2).

Is anyone else experiencing this situation or has already solved this problem?

I appreciate any help in advance.

Did you try adding EMI filters to the power supply lines? This is the most common issue with this type of lasers.

Ditto on what @misken said. If one machine is a foot closer to an EMF source, it can make a big difference.

Maybe buy a clamp-on ferrite and add it to the TS1 ribbon cable. Like this, but don’t pay $20 for just one.

That’s something I haven’t tried yet. Now that you mention it, I noticed that the power supply for one unit differs slightly from the other, including the output voltages. Although they are stable, one supplies 24.5V and the other 24.3V. I don’t think this slight variation affects the machine’s electronics, though it is a possibility.
@MikeyH, I’m going to attach a clamp-on ferrite to the power cable connecting to the TS1 and see what happens.
@misken, what type of EMI filter would be recommended for this machine if the clamp-on ferrite doesn’t solve the issue?
