Please help! Laser moves but wont fire

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?

I tried linking the LAN to my laptop, would that work? I would have to buy a lloonngg LAN to get it to my router but I’m willing to try anything at this point. I just think it’s odd that I can move it from LB, but it won’t run a project

Did you follow the instructions in my earlier post with regards to deleting files?

@berainlb advised, did you ensure there is no files on the Ruida?


To work, it just needs to be on your network. I’ve used a wifi bridge on mine, configured as a bridge. It cost me $12 back when, now they have doubled, but still reasonable… probably as low cost as a long Ethernet cable…

Lightburn also has a wifi bridge that runs on a Raspberry PI, if you have one you can download the PI’s image, for free, and use it. I did until a thunderstorm made my PI non functional.

I have used a TP-Link wifi bridge that I got from Amazon.

If you mean an Ethernet cable from the PC to the Ruida, but you have to know a bit about how Ethernet works as it won’t talk without a reconfiguration of the Ethernet port on your PC.

It just needs to show up on your local lan.
