Lightburn xTool S1 40W - Job Halted

Hello, I’ve been using XCS so this issue usually on comes up when try array’s with Lightburn. It happened about 4 months ago and I emailed support who didn’t have an S1 40W at the time so I just punted an went back to XCS. I now have a Thunder Bolt 32 Pro coming so it’s time to learn LB so I’m back …

What’s happening is that the job stops randomly and not in the same place ( any job of any complexity) with a Job Halted error. I just restart the S1 and resume the job as support taught me so it’s not a huge deal but I would like to know what’s happening. I LOVE (LOVE LVOE) virtual arrays and since I’m keeping the S1 even after the bolt arrives, I’d like to get this figured out.

Job halted

I have neither machine, but from what I have read, this sounds like a USB communications issue. The usual questions are…

  1. Was it ok before 4 months ago?
  2. Did you move the machine 4 months ago?
  3. Did you install new electrical equipment 4 months ago?
  4. Does the USB cable have a ferrite (knot) in it?
  5. Is the cable a USB-a to USB-c?
  6. How long is the USB cable?
  7. Being a MAC, have you tried an active (powered) USB hub between the MAC and machine?

I am not expecting answers to the questions, unless one is the solution. These are for you to use as a troubleshooting guide. There are known communications issues between the MAC and a laser using USB. You might search the Forum for similar issues, using MAC communications as a starter for example, Eventually someone with MAC experience will pick up on this thread.

Hi Mike, it’s the 25’ cable I was using. In looking up the specs, it’s not suitable for this application. I connected with a shorter version from another laser I have and it’s been running for hours now without issue. I have a better cable on order from Amazon and I’m confident this is now fixed. Thanks!
