It’s also simple enough that you can tweak it out and upgrade it in a bunch of ways if you’d like. You can get good stuff out of it (see my Laser Made posts). But they are solid & serviceable if you want to play & practice. They are definitely not in the same class as a GF is (will be). They also have a proprietary software application (LaserDRW or MoshiDRW) similar to ones like LaserCut (which came with the $5000 laser in our MakerSpace). They supply a copy of Corel as well but it’s not licensed and my AV software flagged it. The software I use is my own copy of Corel with their plug-in. Good instructions on how to align the mirrors here: (You’ll learn a lot about Adobe Illustrator, Corel or Inkscape when you get to the software part.) But for $350 you get a decent little laser that can do a lot. No, this is not the machine for people who aren’t comfy with a screwdriver and wrench. When you get it right, tighten up the screw on the end, making sure you have the same slack in the belt as is on the left side. It’s easier to jump a tooth towards the front of the machine than toward the back so take it a tooth or two at a time. Run the rail to the end and measure at both ends of the X-rail to get it right. Loosen that and you’ll be able to push the end of the X-axis rail toward the out of square end and feel it jump the belt teeth (the axle on the stepper motor is toothed). There’s a screw & adjusting nut on the far end of the rail. No need to mess with the X-axis rail or the head - it’ll just be a question of getting the belt lined up right. To square the rail I needed to jump the belt a tooth or two. It just gets in the way and it restricts the air exhaust. While you have the rail out, take the blue exhaust manifold out. Make sure you pull the cables for the stepper motors - grab a picture of the connections so you get them in the right place (if one is the flat cable FFP type that won’t be hard - except which direction is up is something you want to make sure you know - a picture helps). Then there are 4 bolts - two on each end that you take out and the whole rail assembly comes out. That’s easy enough but for you, first you need to get rid of the bed (I did mine so long ago I don’t remember how many screws or where but it was pretty obvious at the time). If it is, you’ll need to take the rails out to get it squared. Just grab a speed square and try to tuck it into the corner. It was about 1/2" out of square in the lower right. It seems its only out of alignment in the bottom right corner
