I have an Ikier K1 Pro Max 48/24watt laser. I have done my color material tests and can get pretty consistent colors in my stainless following those speed and powers. But how do I take an image for a stainless etching and get lightburn to make it do multiple colors in an etching?
Can you post a photo of the results and Parametes of the test?
I have the same device too.
exciting topic
I use GIMP and the colors to layers plugin from gimp_gmic_qt. I then export each layer as it’s own image and import the whole stack of them into lightburn. I them move each layer to the correct lightburn layer, and engrave away!
the step of exporting each layer to it’s own image can be sped uo by saving as an .ora file, then unzipping it. pngs of each layer are saved under the extracted /data folder.
I’ve used gimp for the same thing. Separate the colors, then just export a pdf and it imports into Lightburn without an issue.
Some of the colors only vary by around 100C, you need to maintain this for good color. Using my fiber, the ambient temperature seems to change it also, so it’s a bit touchy.
Good luck

“Color” settings need to be on discrete layers as they are speed/power instructions for the machine. Lightburn has 29 layers so you theoretically have the chance of making an image with 29 different colors. These are discrete settings not RGB or CYMK-type of-color generation (overlayed). I have spent a lot of time with a 60w Fiber MOPA on stainless steel working with color and it is very sensitive to a lot of variables. I would be very skeptical of reliably creating work on a K1 (I also have the Ikier K1 Pro 35/70w).
In practical application, you would generate an image by putting graphic / image segments next to each other (not on top of each other). Similar to this simple example done on the 60w Fiber. You could make it more complex but the segments still would need to be discrete.
i was figuring that would work out best , I am still trying to get colors assigned to layers.
the photo is a materials test grid?
yes it is, It was at 24 and 48 watts
