I’ve been back to playing with grayscale engraving and thought I’d try a mask to get more 3D detail out of an image. The process isn’t dialed in yet but I ran into a problem when using a mask.
I start by doing a grayscale pass of the full image.
I then drew an oval on T1 rotated it and placed it over the face.
I apply the mask and the preview looks right.
When I did the second pass with the mask, the mask is severely shifted.
This is not an issue with my laser. I can make multiple passes of the same image without the mask and it lines up perfectly every time.
