I saw a similar post but figured I wouldn’t hijack that thread as the machine is different from mine.
My machine: Lasermatic Mk2 20W
I have a project with two turtles to be cut out using these settings:
Speed 100
Power 100
Version 1.7.07
The project has 3 layers. 1st the entire pattern minus the outer most outlines. 2nd only the outer most outlines. 3rd a tool layer. (btw when the tool layer is shown and you select an object the sizing handles are not displayed, you have to turn the tool layer off). While cutting I have both the first and second layers set to show and output, the tool layer is turned off.
All of the internal shapes are cut out correctly, first. Then the software shifts to trying to cut the outer outlines. It starts to cut the outline, on the turtle at the bottom, at the tip of the top most front fin. The very tip of the fin gets cut and then the laser turns off but the software continues to move the laser as if it is still trying to cut.
I have to stop the cut, hide the first layer so it doesn’t try to recut it, and then home the machine and click start. At this point the laser goes to the top most turtle and cuts the outline and then moves back to the bottom turtle and cuts the outline. turtle2.lbrn2 (721.1 KB)
You can just drag and drop the files intothe editor or click the button in the center of the toolbar with an upward pointing arrow. You need to wait for the file to load before clicking the reply button on the bottom..
You didn’t show your entire Lightburn screen so I don’t know what start from you’re using. What happens if you try the cut in a different position of the bed, away from the edge?
I’m using absolute coordinates and always homing the laser to the lower left corner of the image (lower legt corner if the image was in landscape not portrait) showing the turtles, which is the front left of the machine, where 0,0 shows on th bed. I’ve had to reposition these, slightly, for a few cuttings and same problem always happens in the same place on that fin. I’ve seen this in another project as well but assumed i had just done something wrong.
Try this. All of your design is open shapes, a whole bunch of line segments, none of the lines were closed / connected. I joined them creating all closed shapes. This may or may not solve your problem. Also, I would delete the guide lines once you dont need them. The issue with now getting select handles is because the lines are so long they extend way off the screen, so just delete them when you’re done with them. turtleEDIT2.lbrn2 (337.9 KB)
Thanks will give it a try. I do know the shapes are a mess. I’m new to this and I’m still figuring out my process to go from a jpg/png ton svg to a project fully cleaned up. How did you join them? Surely you didn’t do them all by hand, lol.
I used a couple tools. First Edit Menu> Select open Shapes, then once selected Edit Menu> Auto Join Shapes. This got most of them. There was a point of the upper turtles lower fin that I manually joined using Node Editor because it wasn’t touching.
