Hello. When cutting the final product along the contour, it is during cutting that a displacement occurs in one direction (if you cut in rd works, then everything is fine, there is no displacement), I send a photo of how it looks. We can’t figure out how to fix it.
I attach a photo of how it looks
What is it that we’re supposed to be seeing here? I don’t see a displacement, but I’m not sure what I’m supposed to be looking for.
We make stamps, on the right you can see a strip that remains, it must be manually cut with scissors so that it does not then leave a mark on the paper after being soaked in paint.
It appears due to the fact that when cutting, there is a displacement to the side by about 0.1-0.2 mm (there is a discrepancy between the layout and the real product). If the program cut out according to the layout, then this strip would not exist.
The most interesting thing is that if you cut in another program, then no displacement occurs.
Maybe it will be better seen here (strip on the right)
And here is a photo that shows that there is no offset in the layout
This is most likely just the order of the cutting operation causing your machine to miss a couple of steps. Is the engraved part an image, or vectors? Which version of LightBurn are you using?
We only have two operations: engraving and cutting. Displacement occurs both when engraving an image and when engraving a vector (the format of the picture does not affect this in any way). There is the latest version of LightBurn
Try this: Set the working mode to ‘User Origin’, with a center job origin. Click Save RD File and save your file to disk, then email that to me (support at lightburnsoftware dot com), along with the original LBRN file, and include a link to this thread. I’ll run the file here.
My suspicion is that your machine settings are a bit aggressive, causing the motors to slip when moving from the engraving portion to the cut. This is very common, particularly with cheaper machines where the factories have set the speeds a little too optimistically.
If you import the RD file back into LightBurn, I’m betting that you’ll see that there is no offset. You can save an RD file from RDWorks and import that into LightBurn to compare them as well.
Thanks, we’ll try tomorrow, but we don’t have a cheap machine. We called a specialist to fix the problems with the cut offset, but checked everything (motors, belt tension, etc.) and we ran several tests, in RDWorks it cuts without offset, says that the problem is in the software. We updated LightBurn to the latest version but it didn’t help.
