Cutting and engraving issues

using xtool s1 40w laser, running LB 2.0.04. problem when cutting or engraving the laser stop about half way thru the job. it has happened about 6 times. this has happening for about 2 weeks. anyone help me.

That’s typically due to USB communication problems:

The Console window will probably show the controller resets every time the job stops.

Replacing the USB cable with a known-good one is a good first first step. Paying enough for a cable with ferrite cores on both ends seems to get enough QC to improve the internal wiring, if you buy it from a known-good seller rather than a random Amazon / eBay / Ali-whatever source.

A cautionary tale about other solutions:

Possibilities:

  1. Laser overheating
  2. USB communications issue
  3. Possible USB energy saver timeout

Details:

  1. Lower the power and speed to see if it will complete the job.
  2. Replace the USB cable with a quality shielded one that has a noise suppressor (ferrite) on it. Reseat the USB connectors on both ends. Look for a RFI (electrical interference signal) that was related to 2 weeks ago.
  3. Cannot help you here, I am a Windows guy.

Half way thru a 5 minute or 5 hour job? It makes a difference.
