Run test job only without laser firing

We are new to using Lightburn, but I have experience with a Co2 laser from many years ago. One of the features the software had was to run the job as a test without actually having the laser on. We have found the preview within the software, but that is not what I am looking for. Hopefully this question makes sense, and thank you for any assistance that anyone can offer.

I’m not sure if I am reading this correctly. But if you set the laser power level to 0% then start, the job will run without laser output


Honestly, that though never crossed my mind! Duh :slight_smile:

Thank you for the slap upside the head. Certainly I am not the first person to want to do this. However, nowhere have I also never seen others do or mention this in beginner videos other than drawing a frame around their target. Seems like a lot of time is wasted in setting up jobs, but again, this grasshopper still has much to learn before the pebble can be taken from the hand! (dates my age I guess, referring to the old Kung Fu TV series).

Thanks for the reply!


P.S. this might be a hard hobby for me for awhile because I tend to overthink things… A LOT! - lol


I remember the Kung Fu series very well, not sure if that is a good or bad thing !
This forum is very friendly packed with extremely knowledgeable people.

Have fun

I often use this to help diagnose a weak power supply in diode lasers.

If a job cuts out at high power and full speed, reducing the laser output to zero (making the laser power draw zero) allows the engraver to literally ‘go through the motions’ and complete the task and confirm that everything else is working if the power supply is marginal or declining.

I remember this… there was also a later reboot.
I’ll post a link for the ‘kids in the back’


I think it’s worth mentioning that there is a very recent reboot of the series that debuted last year.
