Laser will not fire when framing

Can not get the laser to fire when framing.

If you mean by using one of these two Frame buttons then it’s not supposed to fire.

frame

The intent is that you can run the laser head around the extents of the job to ensure that, for example, it’s covering your work piece. Once happy then you can run the job and the laser will fire.

If you hold the ‘shift’ button down then press one of the ‘frame’ options the laser will fire at the low power specified. this is only for diode lasers.

From our documentation on the subject: Device Settings - LightBurn Software Documentation

Enable laser fire button

Diode lasers often don’t have a red-dot pointer like CO2 lasers do, so it is often useful to enable them at low power for focusing or framing. (Please do NOT do this if you have a CO2 laser, as the beam is invisible and this could blind you or start a fire). Turning on this setting will enable a button and a power setting on the Move Window that allows you to turn on the laser at low power for focusing and positioning.

What is the difference between the rectangle frame button and round frame button?

To save too much retyping, I provide our description from our in-progress documentation: Laser Window - LightBurn Software Documentation

The docs are worth a read. We make them to help folks learn LightBurn and to ease support by providing answers to many of the most common questions as well as the more advanced features.

The two Frame buttons are used to preview the position of the job on the laser. The first is a standard rectangular frame, also called a ‘Bounding Box’. This is the smallest rectangle that will fully contain the shapes you’re sending to the laser. The O-Frame button, called the ‘Rubber Band Frame’, traces a path around your design that is the shape of a rubber band stretched around it.
