I have a problem where the lines on my piece have different depths(Material is flat) This problem however only occurred when engraving on plywood and not mdf. I could see that the problem did have some meaning with the acceleration, however even after increasing the slack on acceleration i still have the problem. It did seem to help by having a slight angle instead of a straight line, but that only works on a test piece with a straight line. I am not sure what settings i can tweak to make this work. I feel like it might work if it focused on doing the individual lines instead of a whole segment of multiple lines.
I’m not sure in your case, but it could easily be inconsistency of the plywood. Try holding your piece of wood against a strong light source and see if you can spot any irregularities within the wood. (if your material is not too thick )
Hi gilaraju. It is vectors, i’ve been able to to do the same engraving on mdf with no problem only difference is that is it now scaled to 400x300 where as the mdf was made on 300x400(6400 mm/min 30P)
Here is the file
And the settings i’ve tried playing a bit with(tried changing to fill shapes individually and an angle of 5)
The design already takes 3.5 hours so i am hesitant to decrease the speed
Here is the before and after i did the changes with angle and fill shapes(improvement but still not quite what i am after, but implies that settings could be tweaked)
Sorry long week eyes failed me, 70% yes
Something is up with your module then
Try this test if you can on a spare bit of that wood and see what you get
Also for clarification, when you mean vectors
The image you posted is an image, are you are tracing it light burn or you import the vector itself SVG of AI format?
ok so couple imediat issues
Your machine is set to GRBL M3.
You got to rebuild your profile because if your Svalue max on Edit-Device settings is 255 you are using 25% of your module power
Edit - device settings take a pic please
Devices → double click your profile > what grbl is selected?
Expanding on it so you understand
When machine is set to M3 mode, which is legacy GRBL
The controller does not accommodate and modulate power levels to account for acceleration and deceleration.
This creates this distinct pattern of overburn at the edges.
A bigger downside is M3 GRBL Power range (svalues) are 0-255, where M4 mode is 0-1000
As your controller is M4, and Lightburn is only sendinging 255 as max, you are using effect 25% power
