I recently bought a used Omtech Polar 50W and it tested OK but then suddenly stopped midway through a material test and went back to home for no apparent reason and now says “ There was a problem sending data to the laser. The Machine may be busy or paused”. I checked and there are no files on LB and i have restarted it and the laser multiple times. It moves but wont run any projects. Please help!
Go to Window->File List and check to see if you have a lot of files on your controller. If so, delete all the files that you don’t need to store on the controller.
If you have a Display on your laser you can go through the menus to do the same thing.
If that doesn’t work, share information on how you are connected to the laser.
Follow @berainlb suggestions.
This could mean the controller isn’t talking to Lightburn, a communication problem, so you may have a problem with the USB… or do you have it wired using Ethernet to the local lan?
