    Did you have any smoke problems?

    Smoke problems? Yes. I don’t have an enclosure for the machine, so I keep a fan on and the garage door open!

      Hi Jim, I tried 2D scribed siding on the shed, and it turned out alright. I’ll definitely have to refine my process to get the correct relief. Oh, and diode lasers don’t really like scribing on white mat board or card stock. It will though, but there always the chance for some reflectivity.

      CAD is Inkscape, CAM is Lightburn. I also use Alibre Design Pro for the 3D stuff, and cannot wait to incorporate the router and printer (Elegoo Mars 3)! CAM for Alibre is Meshcam (of which I have yet to figure out) and the much user-friendly Estlcam.

        Thanks for the rundown. I had not heard of Lightburn. I use Fusion 360, and will probably have to write a post processor when I get the laser completed. F360 exports .stl files that the Lychee slicer does a nice job with on the Elegoo resin printer.

          I tried using Fusion 360, but my computer’s graphics card was not up to par. In fact, it’s not even that great for Alibre Design, but it works good enough though the more complex designs take longer to render.

          On a somewhat related note, I placed an order for the Comgrow Comgo Z1 10W laser engraving machine on the 18th that is scheduled to arrive this Saturday. I’m looking forward to cutting thicker materials, those in the 6mm-8mm range. The working area for this machine is 15.75” x 15.75” (400mm x 400mmm). This will be large enough to do projects from N to G!

            I used Meshcam when I first got my Sherline CNC mill. I later found CamBam 1.0 from a British company. I use that for the Robo and Sherline. CamBam has a free version that allows you to do 40 fully functional evaluation sessions before having to purchase the program. I think I paid around $150 for it and it's well worth it in my book. I've tried 360 Fusion and even bought a faster newer computer system to run it. I do all my CAD work with Draftsight 2D and export it to CamBam for the CAM. Another free 3D program is DesignSpark Mechanical. Not as powerful as Fusion but is a good program for getting used to do 3D design work. Design Spark outputs in an .stl format.

            Right now my CAD work is on "slow" speed with the summer months consuming other activities.

            Enjoying your input on this subject.

              It's been almost a year now that I've had the ROBO router/engraver. The machine has given me fits at times, but I've learned all of its little quirks. The machine is great for small delicate work, like the critter shed. It's not as rigid as a commercial router, but for hobby work like what I'm doing it works fine. I had made a cutter holder utilizing a cutter and cartridge from the Cricut Die Cutting machine. Today I received the laser for the machine.

              Here's a description of the laser, "Comgrow 48W Double Ultra-Fine Compressed Spot Laser Module,10W Optical Power, Fixed-Focus Laser,10mm Wood High Energy Laser Cutter, Compatible with Most Laser Engraver Cutting Machine". My hand gives a size comparison.

              So now I have three different ways to produce parts, route them out, cut them out using a knife, and now cutting/engraving with a laser. From left to right, cutter, laser, knife.

              When I went to mount the bracket that holds the laser to the machine, I noticed that the screw wouldn't hold the bracket securely. The screw was not tightening down all the way. I removed the back cover and discovered that the screws were about .062" too long. Had I forced them it probably would have damaged the board underneath.

              I ground the screws down level with the back of the board and remounted the back plate. That fixed that problem. I probably could have ruined the board in back.

              Laser mounted to the machine. It just clips on in front of the cutter motor. Wires are label to where they connect. I won't be trying this out till I do some research on how it's used. Also need to download a program called Light Speed to run the laser. Too many projects going right now to play with this new toy. I'll post an update when I start working with the laser.
