Laser is not burning for Fox Alien 4040 LE

I am having an issue where the laser is not burning no matter how slow I set it or how high I set the power. The laser works just fine in lasrgrbl software that came with the machine but is not working at all in Lightroom. The only thing I have changed is I set the $32 to =1 as the laser was drawing a line between items.

This is worth review: Common Grbl Setups - LightBurn Software Documentation

Thank you. I believe this will solve the issue of origin I am having with the machine, but I have the correct settings this article shows for the laser output, etc., and I still do not get a smolder using lightburn.

Post your firmware settings for review. Also show the Device Settings page for this Device Profile, and we can go from there. :slight_smile:







I appreciate you taking the time to help out with this issue. Please let me know if there is anymore information you need regarding this.

Do you happen to have another software you can try, to ensure the laser is functioning as expected?

I have used it in laserGRBL and it works just fine

I am not sure if I mentioned it here or not, as I have posted this issue a few places trying to get help with it, but it I was able to successfully use the laser in Lightburn until the other day. The day before it stopped working I had designed a piece and ran it. I noticed that it had drawn a line from the graphic to the wording. It just so happened that someone in the FoxAlien group on FB had the same issue and they were informed they needed to set $32 at 1. So, that evening when I got home from work, I set $32 to =1. I am not sure what it was at prior to that, as I did not look. After that it no longer engraved using Lightburn.

Share your current firmware settings. Go to the Console window, type $$ followed by Return / Enter, then scroll that window to copy and paste the results here for review.
