Nodes won't snap together

There is a thread with my exact problems from a couple oof months back. Unfortunately, while the user was able to resolve the issue by breaking apart the shapes and rejoining, that solution does not work for me. The nodes all appear to be snapped together, but receive the following error:

Choosing “view” results in:

Please advise.

Node Eding works fine for you, it’s visualization of results that is your problem :wink:

There are also a few “construction defects” that I have corrected manually. In Node Eding, when you zoom in very close, you can see that some lines are put together with the wrong nodes. You can only manually correct them.
In addition to that, I will change the script in the Inner Circlen of the Sterne with non -traced writing, i.e. write and paste it.

Hi, and thank you for your response. I’m not quite sure I understand… Are you saying these two nodes won’t connect as they are the wrong type?

Also, did you edit and upload the file itself? There’s a png attached, but if I import it this is what I get:

And what is the significance of the filled/smooth option?

Appreciate your input.

I haven’t reviewed the overall design but for your specific question, note that nodes can only be joined in pairs. You cannot have 3 nodes joined at a single point.

I see, so you cannot join a send line in the middle of the first line. That seems a bit problematic. How does one work around that? I suppose I could connect the two ends of the different shape together, then move them together so they are two separate shapes but appear as one?

This is really design dependent. Primary strategies include stacking of shapes or placing shapes directly adjacent to each other.

Hmm… although upon further consideration, I’m not attempting to connect three nodes together. I am inserting a node in the middle of one line, then trying to join a second node to the line.

Also, that doesn’t explain using the same method why some of them will join, while others will not. As you can see here, one of the circle shapes is connected, while others are not:

When a node is inserted into an existing line segment the net effect is that you have two line segments joined by their nodes. From that perspective, the scenario becomes the same of attempting to join 3 nodes.

Closer inspection of the design will reveal what’s going on:


The node at right is indeed joined to another node on the circle but the circle itself is not a closed shape.

Think of them as segments not nodes. Only two segments can be joined.

sorry, but I was busy with some orders that had to leave the house.
But you got those answers already. An easy rule of thumb is, if you cannot fill the desired shape, then it is not closed :wink:

I downloaded your file and edited it, and sent a screen dump.
I’ll just open the other computer and send you the edited lbrn file.

Here’s your file, edited

You see what you are filling out and the two options are related to one’s computer power.

Lol. No worries. I appreciate the time you’re taking to share your knowledge. I don’t quite understand it all, but I am sure closer that than I was prior to this conversation.

Thanks so much!

… that’s not good enough :wink:
We want to help you understand what you are doing, what are you missing in the process?

Ha ha! Once I get a chance I am going to look at the file you uploaded and compare it to what I was doing. Once I have evaluated it further if there are gaps in my understanding I’ll clarify my thought process in more detail.

I looked at your edited file, and the text was cleaned up very nicely - other than the year 1889. Well, it was cleaned up as well, but is mirrored haha - nothing a little ‘flip horizontal’ won’t cure.

I still have the same issue I started with, however.

Your edited file does now include border, but does not show the ‘star’ around the text you edited – I assume because Lightburn can’t fill shapes that are not closed. But that does bring up the fact that somehow a couple of those shapes WERE closed, leading me to think the rest of the shapes could be closed as well.

So that is part of my lack of understanding, as well as from your earlier response you stated, “when you zoom in very close, you can see that some lines are put together with the wrong nodes. You can only manually correct them.”

I took that to mean there were other nodes I COULD connect, or that I could close them manually. If you offered a suggestion or solution regarding that, I have somehow missed it… Hopefully I articulated that well enough it makes sense.

Edit: This may give you an idea of my process… here is the original image that prompted me to start this whole thread:

Yes, it went a little too fast. The star must be “separated” and of course also form a closed Shape.

Your original image is colored and has different shades, it always makes it a little difficult to reproduce it to laser use, but you have already found a reasonably fine compromise, I think.
A problem I see in the size of the stern content, it will not get good out of the laser machine if the whole logo is too small. You might try to invert content in the star and see if it becomes more clear.

I haven’t been very accurate it’s more think like a demo :wink:

I hope you can use it otherwise we have to look at it again tomorrow, it is half past 1 at night here and I have to be in my workshop at 8 am again.

No worries. Have a great night!

I have learned that joining nodes is kind of like nuclear fusion. Intense heat and pressure to get them to join.
