@NedManIn today’s adventures in Laser Crafting I found a largish mirror curb side on the morning walk. It’s about 22”x28”, so too big for my 50W laser. But guess who now has access to a larger bed 60W laser machine through their local maker space.

@NedManGoing to engrave the back and I needed to remove the mirror from the frame. Soo many staples. 
@NedManUsed a pair of beefy needle nose pliers and a dead blow hammer to tap them loose with a few lite taps.
@NedManI measured and marked the vertical middle of the mirror. My design has a group of elements at the top and another at the bottom. From the software layout I found the horizontal middle of each group relative to the respective closet edge. Marked those horizontal middle lines on the mirror as well.
@NedManI had to use the pass through slot opening on the machine to fit the short side of the mirror into the bed area. #LaserEngraving #LaserCrafting #MakerSpace
@NedMan@social.makerforums.infoI used the horizontal lines to set the mirror edge parallel to the x-axis by running the laser head and laser pointer down the marked line and adjusting the mirror until the laser pointer stayed on the line from one side to the other. #LaserEngraving #LaserCrafting #MakerSpace
@NedManFinding and marking the middles allowed me to set the Job Origin to Center in Lightburn and then position the laser head over the intersection of the lines on the back of the mirror. Then started the engraving. Since the job origin is set to center Lightburn engraves everything relative to that point. #LaserEngraving #LaserCrafting #MakerSpace
@NedManSince this is being engraved from the back I had mirrored the engraving so it faces the right way when viewed from the front. Top went fine. Very happy. Rotated the mirror to do the bottom and did a vertical mirror of an already horizontal mirrored engraving which turned out to be a mistake since physically rotating the mirror canceled out the horizontal mirroring. Should have just rotated the horizontal mirror image instead of doing the vertical mirroring.

@NedManCurrent plan is to cut off the bottom and engrave correctly. Will also have to shorten the frame. Oh well, live and learn I guess. 
@NedManEnd up cutting off the bottom. Then engraved the bottom the right way. Now I just need to cut the frame down. Still a relatively large mirror at ~ 22” x 23”. #MakerSpace #LaserEngraving #LaserCrafting
@NedManSince I engraved the back I will be painting the back to match the frame. So the engraving will show up dark. Test painting shown on the cut off piece. #MakerSpace #LaserEngraving #LaserCrafting
@NedManOk, finally wrapping this project up. Cut the frame down, glued and used some flat angle braces to reassemble. Painted both the frame and the back of the mirror. Hung it in the laser room at the maker space. Looks good.

@NedMan When I saw the picture before reading the text, I thought that it was a visual pun on mirror!
I think you should keep it.
@NedMan@mcdanlj Lol, maybe. 
@NedMan That looks great. 
@NedMan
Oh no!
Damn, that's an easy mistake to make.
Similarly I still have two rubber stamps of my logo that now print in reverse.
