After aligning targets using print and cut my cut lines exceed my frame; even though the file and substrate fit entirely in the working area of my laser bed

LightBurn Software Questions
1

As mentioned above; I set my file up in light-burn, aligned my targets and set my alignment to the scaling option (I have tested both). Then after I look at it in the preview window it shows my file being out side the bed/frame. It also shows a gap where the file could have been in to allow it to fit inside the bed. I will include pictures for clarity. I have framed the file out and it fits entirely in the bed(even though it is literally edge to edge). Additionally my substrate fits within the bed as well. Any feedback is appreciated :slight_smile:

You can see at the bottom of the image where the line overlaps the frame.

Also absolute coordinates is on and I used my onboard laser controller to move the head. also I have less than half an inch of room between the top and bottom of the file and the edges of the frame/ bed

2 suggestions:

  1. Does the gap at the bottom actually cause a problem? What happens if you frame after going through print and cut?
  2. It looks like the design goes basically edge-to-edge of your work area. This means that you will need to place the material precisely such that it fits entirely within the boundary of the machine even before print and cut is applied. This may be exasperated by print and cut since once applied, LightBurn can shift the logical location of the design relative to the print bed. Try running a frame of the entire design before applying print and cut and make sure that the material fits within the existing frame. Only then try applying print and cut.

  1. yes the gap means that when i send the file to the laser the laser returns a frame slop error.
  2. will try

after Framing and looking at the output preview before print and cut i can confirm. the file fits within the bed/ frame with .3" of space

The issue is almost certainly going to be related to getting the aligned print and cut to work within your workable addressable area. If you’re able to frame the original design within the printed area of your material before applying print and cut then you should be able to get this to work.

I would suggest not using scaling in order to ensure that the design is not scaled larger assuming the printed output and the design in LightBurn is 1:1.
