This is not entirely uncommon with that board and can be caused by a number of things:

  • poor quality USB cable
  • improper grounding
  • power noise from chiller, air pump, etc

If the board re-homes, it means the USB connection dropped. C3D has guidance on their forum for troubleshooting and fixing this.

hmm thats well crap for a £200 board …

any reason why in optimisation settings if i select both top or bottom - it goes from the bottom (nearest origin) - trying to get this complete so i can then look into the issu

It’s not really the fault of the board - if the supplied power isn’t clean, or you’ve got a ground loop, it can happen, and it’s not terribly hard to correct. Most Chinese lasers come with an EMI line filter for this reason, but a K40 cuts every possible corner to get it to the price point it’s sold at.

For the direction, if you are scanning something, it runs based on the angle you’ve chosen in the scan. If you want it to scan from the top, set the scan angle to 180 degrees. If you’re scanning many things, they’ll be ordered from top to bottom, but the scan angle controls the direction of scanning per item. In the pic below, each individual circle is scanned from bottom to top, but they are run in order from top to bottom (as I’ve numbered them):
