Does your laser head regularly pause for cooling?


You will only get this software message, when the laser head exceeds a certain temperature. It will then pause for 30 seconds for safety reasons. This should mostly be ok. However, if you are seeing this message very often, please check the following: 


1. Is the laser head dirty and needs cleaning? Or have you put it back together incorrectly after cleaning?


It depends a lot on the materials you laser cut and engrave how often you actually need to clean your laser head. If you work a lot with leather, wood or paper, we recommend to clean your laser head more regularly, than if you are working with acrylic, felt or foam rubber


If you receive the cooling warning message right after cleaning your laser head, it's a hint that you have probably assembled your laser head incorrectly. We have put together a tutorial on how to clean a laser head. This is also where you can double-check, whether you have put together your laser head correctly, as well as in this video:




Important: Please make sure the fan's opening is facing up, so that the air can circulate in the right direction. Please make sure the fan cables are not squeezed between the both sides of the heat sink when they are put together! And please make sure the heat sink closes tightly!

2. Does your air filter need to be changed? Following signs will help you to answer this question:


  • Are there fumes and sharp smells inside the devise housing of your Mr Beam?
  • Is the fan inside your Air Filter rotating faster, thus making a louder noise than usual? 
  • What filter status are you getting in the software? (Settings > Maintenance)





Step 1:

Please replace your pre-filter mat with a clean one. To do this, please unscrew the lid of your filter and lift it to remove it, then take out your pre-filter mat. The more often you change your pre-filter, the longer the main filter is going to serve you. You can order a pack of new pre-filters in our shop


Step 2:

If you don't experience any improvements, please replace your main filter. You can order a new filter in our shop





We have put together more information on the air filter system in this article.
