My machine is stuck in PAUSE... Return to top of page

If you laser machine control panel says that the machine operation is paused and to press start to continue, but pressing start doesn't make a difference...

Check that the base tray in your laser machine is squarely pushed in all the way.
This is a safety feature to ensure the laser machine is not operated without the base tray in the machine to catch parts and debris when laser cutting.
The best way to ensure the tray is correctly in place is to pull your tray out by at least 200mm and then, using both hands equally distanced along the front tray edge, push the tray back in until it cannot go back any further. Make sure that you have pushed the tray in squarely and firmly.
If the problem persists, clean out your tray, and ensure that there are no debris stuck to any part of the tray or located in the slot in your laser machine that the tray slides into.
In the event that your problem still persists, please contact your supplier for further advice.


The spot size of my laser where it touches the materials (laser bed) is different Return to top of page

Should the spot size of your laser beam (where it fires down on the laser bed / materials) be a significantly different size than usual, this may affect the quality of the cut/engraving and impact on the power of the laser when trying to process materials. If so, please check that;

  • The laser alignment is correct. PDF
  • The mirrors are all cleaned and undamaged. PDF
  • Both sides of the lens are clean and undamaged. PDF
  • The lens is located the correct way round in the machine. PDF
  • The air assist is turned on, operating correctly and blowing down through the lens nozzle.
  • You are operating at the correct focus height for the lens in your machine (the focus gauge provided only applies for the specification of lens originally supplied) and the material thickness you are processing. PDF

Should the above checks not resolve the issue, please contact your supplier for further advice.
