I am etching small wooden boxes and after a few minutes into the etching the laser shuts off but the machine keeps moving. I took out the box lids and put a scrape piece of wood and the laser etches the image. when I place a new box lid and hit start the etching goes for a few minutes and shuts off.
I have ruined two box lids and I cannot figure out what I am doing wrong. I have the same settings on the scrape wood as I do the box lids. I have a x-carve 1000mm with j-tech 7w laser
