    Great job @Bruce Walker ! :thumbsup: Life has a way of getting in the way of a good build sometimes :D But you pushed though and are rewarded with a super sweet setup man. Nice one.
    Do you have plans to paint and if so what colors? I would love to send you out some of the new OpenBuilds stickers to tag this build!
    Keep up the great work and thank you for sharing

    Thank you, Mark. I am kinda proud of it. It is still a work in progress. I need to go back into my story and add how I added a custom Z axis with a custom quick-change tool mount so I can use different lasers. I also hope to get a drag knife setup working for cutting vinyl and such.

    First, I plan to put the box to work making some custom Christmas gifts, but I do plan to paint it. I have a battleship gray color in mind. It would be great to have some OB stickers to tag it. Can you get my address from the Part Store? If not, message me.

    Thanks, again, for the kind words.

    Why yes; yes it is. I forgot to mention that I 3D printed a custom Z axis in my build story. When I realized I would need to move the laser up/down to preserve focus based on the thickness of the item I was etching, I decided a Z axis was needed.

    I will write up the Z axis add-on in a Project and include my STL files. After I finish that write-up, I'll add a link to it in the build. I'll also add a reply to this comment thread after I do so you should get notified.

    I'll be printing a set of these once i figure my PETG settings. Never realized how much of a PITA it is to work with all-metal setups.

    Yeah, especially for PLA; ABS is easy to print with an all-metal E3D V6.

    PETG can be messy to print. Getting the settings dialed in to prevent build up of filament on the nozzle takes a while, and getting the first layer right is pretty critical because build up of filament on the nozzle will peel your print off the print bed. I seem to have to fuss with it for a while any time I switch back to PETG.

    I print PETG a lot. I put acetone on the build plate then take left over ABS rafts and smear it where I will be printing. I am using an Anycubic glass plate. Then I print the PETG over the top. I usually print it on a raft. The first layer will definitely stick. Sometimes I have a little difficulty removing it. My theory is the two have a similar melting temp so the PETG sticks well to it. Or maybe it is just luck. I haven't had a part come loose since I started doing it this way.

    Sounds like a winning solution. I've never used the smear/slurry adhesion techniques.

    For PETG I print on FR4 board lightly sanded and use glue stick. Adhesion is good, but if I try to print my first layer too thin the nozzle gathers filament as it prints - especially when doing solid infill - and as the sticky mess on the nozzle grows the problems multiply. ABS is much more forgiving in this regard.

    I started doing it with ABS because I was getting some warping and parts coming loose. In fact it works so well for me ABS has become my favorite material to print with since it so easy to "acetone weld" parts for a large project. It helps that it is the cheapest, too. :)
