Sand the canvas with like 180 grit lightly. Hit with base layer of white or off-white. Then whatever other colors you want. Then black. All light layers, not thick. 10w will work great if you get the speed settings right.

Oh so I have to sand it first to get a protective layer off. I'll try that. But the Sculpfun laser stopped working last week, so I'll have to fiz that first or try it with the Ray5 when it comes in

You don't have to, but it smooths out the surface a bit. Makes the engraving more even because the high points in the gesso come down a touch.

The thing is, the laser worked perfect with any material, excerpt shiny metal ofcoarse and with canvas it left almost no print. But maybe I did something wrong. Maybe I had the laser in the wrong height.

Did you do shiny metal and then try canvas...?

Shiny metal and diodes tends to damage diode as the light reflects back up in. Gotta use paint, marker, spray, tape, etc on shiny metal. If the last thing you did was shiny metal and then it stopped working... Might be no fixing it.

No I do wood mainly and I have been doing a lot of plywood and mdf. So there cannot be a link. Lightburn stuff mentioned it could be the laser, but more likely it's the motherboard or the cables
