The BOM listed is pretty much worst case scenario. A lot of items (that aren’t from Misumi) are more “Market Price” and I just listed whatever I found to be the upper end.
I build the units I have (3 currently) for about $350 each
That’s mostly left up to the user at this point though I’m sure I’ll be releasing at least “reference designs” for that in the near future. Assuming you have a relatively flat and level surface, nothing more than some rubber feet on the bottom (recommended in the coming-soon build guide) is more than enough.
But you may notice that there are cutouts at the bottom of the enclosure panels - This is so that you can attach to the T-slot extrusions. At the least I’ll release a design for a simple L-bracket that attaches there that can then be used to either screw or clamp down the machine. But mostly I find it unnecessary.
Depends a little on your software but there are a couple ways I do this (usually both):
- There’s an enclosure panel designed to work with most of the laser modules out there that provides a “targeting frame” of sorts. It’s 135mm square and has tick marks along all sides to aid in visually aligning everything.
- In software I tell it to move to X65 Y65 (which is dead center of the work area) and then either using the focusing button on the laser module or a similar option in my software to turn the laser on at ~1% power, I use the laser dot to aid in placement and then make sure in the software my design is centered.
It runs grbl so anything that supports grbl like LightBurn, LaserWeb, LaserGrbl, etc. I use LightBurn because I value my time and puts everything else to shame I’ve even gotten LightBurn to work quite nicely controlling a pen plotter modification that will be available for the machine.
