I have a Preneex 60w Blue China Laser with 2 different types of rotarys.
I have burned multiple images about a dozen times on 2 different rotary attachments. I also have tried importing a .ai file and a .png file into Lightburn. I have tried burn .png image, burn .ai with fill, take .png and do image trace. I keep getting the same result. I tends to skew about the same spot on all the images. It starts off great and then towards the end of the image it gets skewed. I have already used up 6 yeti cups. I have yet to get one to come out correct. I have tried a lot of different speed and power settings. Any help would be helpful.
