I have a workflow that relies on UDP commands to load files and start the laser. Some designs cause it to trigger the duplicate detection popup on cut “start”. This popup requires a manual click to “continue”. I cannot find anyway to disable this check, and it has broken my workflow.
No, having duplicates did that. Duplicates mean you will run the same path again, doubling your burn time for that section. I have seen, and personally experienced, many duplicates in a design. Worst case is when it is not exactly a duplicate and Lightburn does not catch it.
Use the Preview window at very slow speed and you can see wierd travels.
The solution is to clean up the file. Garbage in, garbage out.
The duplicates are not the problem. I want the machine to cut what I tell it to cut.
My issue is that Lightburn has a smart feature to detect this that there is no way to automatically disable. So when a file has duplicates in it the machine (which I am not actively supervising) freezes until I go over and manually click continue. For my purposes this smart feature is a huge headache and time suck.
Can you use multiple passes to accomplish this? I have not heard of, until now, anyone doing duplicates to accomplish multiple passes.
Not really… I need specific control of the order of various passes so I’m loading one large SVG file.
My current workaround is adding a few microns of noise to the vector paths so it fools the smart features. It works but frustrating that Lightburn has smart features that are getting in the way of using UDP automation effectively…
The other pain point I ran into is that it automatically centers the graphic unless you hold shift during import… Well of course if you’re doing things via UDP you can’t hold shift (and users of UDP are pretty likely to want to control object placement external to lightburn). So now all my graphics are framed with an extra rectangle that is on a layer that isn’t outputted…
This is the source of your problem, and adding “noise” to the vectors is making those vectors non-exact.
I your SVG proprietary? If not, add it to a Reply (you may have to add .txt to the end of the filename). If it is proprietary and you trust me with it, do a Message and attach it there.
I will examine the file, remove the duplicates, if I can, and let you know how long it took me.
The SVG is proprietary, but also kind of besides the point. Yes there are things in the .svg that are duplicates. I want those - I’m using them to get more control of the number of passes & order of the laser paths. My issue has nothing to do with the data in the svg.
If I could automatically force the machine to start the job my issue would be gone. My issue is that duplicates trigger a popup window that needs to be manually clicked. I’m controlling the laser machine via a server that is controlling Lightburn on a laptop over UDP. If you’re familiar with 3D printers & octoprint it’s like if the printer requires you to manually click on the UI when you send a job over the octoprint server. Sure there might be a valid reason for it to be want you to double check, but it’s really frustrating if you can’t clear the hold from octoprint.
I just did a search of Lightburn looking for something that says ignore duplicates, and found nothing. Your desired workflow, whether it be out of habit or necessity, does not currently suit Lightburn. I can only suggest you submit a Feature Request (https://lightburn.fider.io/) and see if you can get it upvoted.
Emailing support@lightburnsoftware.com will probably get the fastest, most direct answer to your query. I could not find a way to disable the check either.
May I suggest something that might work for you though? Move the duplicates to a different layer with the same settings. This would run your main single graphic on one layer then a single set of duplicates on another layer after the first one finished. If you still need multiple passes on an area you could use the pass number. If there are areas that require more runs, move them to another layer.
Just a thought.
