what about changing the laser head?

Did you focus the laser? It's very important to do that every time you put an object under it that is of different height. If it's not focused properly, it won't burn but just scan and you will see nothing. Also, if the intensity is too low it also won't burn.

I am having a similar issue. It seems like the last two engravings I did became progressively lighter. I have attempted to modulate the amount of time the laser burns before moving on, but it doesn't have an effect. I was wondering if anyone had a solution?

Did you ever find a solution?

I ended up getting a full refund. Thing is just sitting around collecting dust now.

Did you find the solution to your problem?

I'm having that issue with mine. Did you find/get a solution?

Same thing for me :(

too little engraving time
