Huge ghosting issues


I am having big ghosting issues with my Ortur laser master 2. Being new to this, the results were surprisingly good for like the first 8 prints but then at print number 6 I am sudenly experiencing these problems and they get worse every time so far…

I have checked the belt. Not too tight and certainly not too loosen. Also, the rollers seem fine and the machine has good balance while engraving. I have attached an image that has been engra

ved. Ghosting is clearly visable.

Post the file. That’s very unusual.

I’ve seen ghosting due to a poorly-aligned CO2 laser mirror, but never like that on a diode.

How many passes are you running and does the ghosting happen at the start, in the middle or at the end of the job?

Not sure when the ghosting appears, just facing with this end result, I´ll have to check and pause the program in the middle of the print to tell you. I´ll to this today.

A couple of things:

Try ‘fill shapes individually’, instead of ‘fill all shapes at once’
Try just ‘fill’, rather than ‘line and fill’ and see if it makes a difference. It may be that the ‘line after fill’ is the source of your ghosting.

Changing from ‘fill shapes at once’ changed the run time from 3:29 to 1:54

I would also look at increasing the power and speed - if you turn the power up from 21,7% to 50%, you should be able to double the speed.

Lasering is all about light pressure/time.

Changed the settings according to your recommendations and the problem was solved, also way faster than before.
Thanks a lot Bo, you made my day!
