Hope you all are doing well.
I’m starting on the forum with a simple but strange / unwanted result from an engraving project.
I have a very simple leaf made of 2 objects. the outer and the inner line. I want to engrave the space between the 2. I can notice that the machine mark both in and outer line not the space between. I’ve check and both object are closed.
Here are pictures to show what I talk about :
Both inside and outside lines must be on the same layer.
If one of the objects are duplicated, then you will get the results you show. Open EDIT and select DELETE DUPLICATES.
From your preview, it looks like it should work. It really helps to upload the file here, so we can poke at it on our machine. Bottom right of the reply box there is an icon to upload files…looks like a computer with an up arrow on top.
The picture suggests the Scanning Offset Adjustment isn’t set correctly: the figure is duplicated with a significant offset from left to right, presumably along the X axis.
However, the speed & power values seem very low for a 100 W CO₂ laser: 30 mm/s and 2%. At that speed, I would not expect the Scanning Offset to make much difference, which implies there’s something loose in the X axis drivetrain.
To help track it down, this test pattern helps identify mechanical problems:
Scale it to fit the platform and run it as fast as it will go in Line mode with optimizations turned off and power set to mark a sheet of cardboard. Any differences from the design will be informative.
Upload good photos of the result so we can look over your shoulder.
I’m going to make some tests with the offset adjustment and comeback to you.
as for the loose belts I’m sceptical, the machine is new but it may be possible.
Perhaps it’s a loose setscrew in a pulley, a loose screw in a belt anchor, or a stripped screw holding the laser head in place. From what we’ve seen around here, anything is possible.
The point of the test is to check for mechanical problems; if it doesn’t reveal anything, that’s good.
So I’ve made some tests ! I’m happy to say that the problem is solved.
I’ve made the offset adjustment to line up perfectly the fill lines and the result is perfect to !
