Framing includes layers with Output off

Hi, I have a problem in Lightburn with framing. I have 2 objects on my working area and each has a different layer. When I set the output switch of 1 layer to off, I expect it not to be included in framing, but when I press frame, it also frames the non output layer. Today that caused a crash of the laser head into the handle of a mug, because the chuck rotated the mug to the position with the object with the layer that should not be output. Fortunately no damage was done, but I think that must be a bug. Why would I want to see the frame over all objects, even those that have the output switch set to off?
Is there a setting somewhere to exclude Objects with no output layers from framing?

Cut Selected Graphics switch in the Laser window?

What is your start from set at?
When I use current position and disable one object, the green dot doesn’t move so I assume that it is still going to frame both.
Don’t have my laser hooked up so only a guess.

Start From is set to current position, but it does not really matter.

You can try it out simply without even having a laser turned on.
Just draw 2 rectangles on different places in Lightburn and give each one a different layer. Then switch one of the layers output switch to off and then click on the zoom to frame selection button. It will show both rectangles.
I guess, if you send the frame command to the laser, it will frame both rectangles. That is not a behavior I would expect and I think it is wrong as long as someone could tell me a good reason for that.

The problem I have with that is, that I sometimes place some objects on the working area and then decide to laser on and not the other one. So I switch the other ones output switch to off. As framing does not work as expected, I have to remove the other one instead of switching ourput to off, just to get it back by Ctrl-Z after the job is ready. That is weired and in my opinion totally wrong.

I also think, that the green dot that shows the Job Origin should not take layers that are switched to not output into account.Not output layers should just be ignored as they were not present. The totally weired thing is, that they aven are not ignored when they are set in invisible by switching the show switch to off. So t is easy to oversee this and having a hard time, when trying to figure out, why framing does not work as expected.

That does not change anything to framing, as far as my experience is.

Hello Helmut

Please provide your LightBurn version

Post a screenshot of your LightBurn showing the layers selection and if possible the LBRN so we can try to replicate the behaviour.

I have Lightburn 1.6.03, gcode version.

To replicate the problem should be easy. I just opened Lightburn added 2 text objects and assigned each to a different layer. Then setting the output switch of one of them to off and hit the “zoom to frame selection” button. Then it zooms in to show both text objects, instead of only the one with the output switch set to on.

Yesterday, when I used the chuck, I had a project with 2 objects. I just put on object out of the way and set it to not output. Then pressed frame and it crashed, because it framed both. At least it looked like it did.

After that, all my testing was just with the “zoom to frame selection” button.

Now as I wanted to reproduce the wrong framing without the rotary, the “zoom to frame selection” button still behaves wrong (in my opinion), but the actual framing now works.

I am really sorry, but I am pretty sure, yesterday it crashed into the handle of the mug, because it was going way too far and I think, it was because of the second object, that was set to no output.

Here is a screenshot of my test from today with all the settings. With this test the “zoom to frame selection” button still does it wrong zooming in to both objects and not just to the one that is enabled for output, but at least actual framing works as expected.

I am a bit confused now.

I think the word here must be take literal but not conflate frame selection - with Framing the work on the laser. I can see the confusion.

When you click Click to frame selection - it will do one of two things
a) if you have ONE or multiple objects selected - it will zoom to make those objects fit in the screen
b) if no object is selected - it will frame all objects on the screen to the maximum zoom level possible.

This will not take into account the output of the layers.

Think of the button as “Zoom to Fit Selection” instead and I think that makes it clearer.

Just to add:

  1. If you select your shapes or Ctrl + A then switch C01 output to off

    .
  2. If you switch off first then select the layers you want

Thank you for the clearificartion. Makes sense now.

Thanks. Good idea.
