I’m having a strange issue with a logo I have designed. The logo file is working, and I have burned it before, but If I copy and paste it into another documents, I then do a preview, and I get an error about open shapes.
Clicked show me an it highlights the open lines.
Tried the all options under “Edit” to close path, or auto-join that I have seen where and also suggested on Google, but they do not seems to work
What I don’t understand is that if I do a preview of the file itself does not show any open lines…
This is really annoying, as I have a file with coaster position and I need to be able to but the logo on the back
I have Lightburn 1.3.01 on Linux Mint 21 Ortur 20w diode
When you get the error, and do the “Show Me” option, does it highlight anything?
If it does highlight something, zoom in a LOT and look for gaps, usually with one shape having more than one large green square. Then you can try “Auto Join” or drag the ends of the lines to connect.
The problem is that each node on a path can connect only two lines. The vertical lines on your design are separate lines, with a node at each end, and cannot connect to the horizontal sides of the rectangles and lines at their ends.
You can mark those lines as vectors, but you cannot engrave them as filled shapes.
If you redesign the logo using thin rectangles, rather than lines, it should work better for engraving.
So these can’t be joined to make it like the one on the right. I had someone ask this question and the only way I could do it was to make two separate pieces and group them.
Correct: a T intersection at a node isn’t possible.
You can abut two closed shapes, so it looks like they share a common side, but that “line” is actually two overlaid sides from two separate shapes. The optimization setting Remove Overlapping Lines should take care of cutting only once along that path.
Thanks for your reply. That might well be the case…but I think you have missed the point in my question. The design works on it’s original file. The problem is when I did Copy/Paste into another project, with the coaster positioning marked, so I can laser it on the back.
I have tried to import instead than copy/paste, but somehow it seems to still mess up the design.
I did this before, is not the first time that I used my logo… that’s what i find odd.
Sorry, I did not address that “back of item” alignment problem.
It makes me think that when you copy/paste it, you might be picking up some little speck of something that becomes a problem with alignment on the pasted side.
I do a lot of aligning front to back on coasters, and I will design the front, select all of the front design including the cut line for the outer edge of the coaster, then I just flip it vertically, delete the front side artwork, then put the backside artwork where it belongs. I usually register the cutting origin in the upper left on both sides, but I know some people do it in the center for flipped items.
Hi Patrck
I engrave on slate coaster so I do have a cutting line
I have a cardboard cut out of the coaster tapered to my wood board for positioning.
What i did was click & drag to select the logo and copy and past it to the other project.
If there was any “specs” on the drawing, would it not create the same preview error on the original file as well?
I’m gonna try to burn the original file and see the results.
You would likely see any speck in the preview, except the preview zooms into the object selected so you can’t see the larger area to make sure anything unwanted might affect the location. So my last “shot” at this is to do both sides of the coaster in the same file. Don’t have another “project” file different than the frontside file. Using a cardboard cutout is how I do the front-to-back alignment.
SOLVED (kind of)
Thanks for the replies. I realised what the problem is, kind of…
As I mentioned, I am still a beginner, so this was a stupid mistake.
The original file the blue layer is actually set as line, so it burns OK. If I switch to fill I do get the same error.
When I copy/paste in the other project with the coaster template, I had another design outside the table that I burned previously, so it picked up the blue fill layer from the other design…
I did a bit of tweaking on the design before I even realised it.
Actually do like the line finish more than the fill, so I will leave it as it is for now
