When I looked at my slate with a very strong lens I discovered small bulbs of yellow glass near where I engraved. These were only visible after a transition out of a white engraved effect to a high power.
You may find that very low power prevents the slate from making yellow-glass where the laser impacts it. This advice may not work for your slate as chemistry will vary from stone quarry to stone quarry. Different samples of stone may make the finished colour that you want impossible.
As an experiment I would attempt a High power run to generate as much yellow glass as possible then a second pass at a lower power to fracture the glass to make a white surface.
I encourage your to continue experimenting… I believe that you can get the results you desire.
Also es ist besser. Habe andere Marke und da war es nicht Gold. Zweimal Laser funktioniert nicht perfekt. Obwohl ich nicht verschiebe Laser er nicht genau. Egal man Merk aber ein Unterschied und es wird „heller“
Danke für den Tipp
So it’s better. I have another brand and it wasn’t gold. Laser twice does not work perfectly. Although I don’t move lasers it doesn’t exactly. It doesn’t matter, but you notice a difference and it becomes “brighter”
This appears to be ‘lost motion’. It happens when something is loose on the machine or when commanded high speeds overwhelm the machine. It can also be caused by stray electrical noise interfering with data transfer.
Your previous work was perfect in this regard. If you have changed speeds or any cords or nearby equipment go back to what you were doing previously and see if the problem is corrected.
DIe Zahlen geben die Maximal Geschwindigkeit vor. Ich hatte mal versucht was mit 180mm/S zu lasern. Lightburn hat gesagt es dauert 2h es hat bei mir aber immer 3 Stunden gedauert. Der Max wert in der Konsole war ca 6000. 180mms = 10800. Ich habe den wert in der Konsole auf 12000 geändert und schon hat das Projekt immer genau 2 Stunden gedauert
