  • For starters, I have a Prusa printer, Moose 3D scanner and a full license for Fusion 360, a small custom built CNC and a good selection of specialty tools.

    If needed, I can revert to photogrammetry for capturing high detail on small parts. (Probably within 15um/.5 thou? I need to test the limits of what I can actually do before I say for certain…)

    I can scale printing super fast and am lucky enough to have a Microcenter near me so I can buy more printers and filament in a hurry. (Now that I think about it, I’ll probably order a resin printer this evening. It’ll be useful for my own projects where I need to duplicate some injection molded parts.)

    For now, I am going to let the jobs determine the scale of my operation and how I invest in additional equipment. Thankfully, I am decent enough at the mechanical aspects of this stuff to handle issues fairly quick.

    But yeah, I already have a few thousand dollars in tools, assorted parts and filaments. It’s the odd tools I have that give me a good starting advantage, me thinks. (Nobody else I know has a full set of pin gauges, as an odd example. My electronic component and fastener selection is also fairly substantial.)

    Honestly, it’s time to get an ROI from all of my own, personal projects that I have made substantial investments in over the years.














  • Just isolate the problem, is the rule of thumb. If you can replicate the issue reliably, it’s fixable. At worst, it limits the number of variables you are working with, which is still awesome in its own way.

    My only other thought would be a bizarre stepper motor skip, which would lead me to start checking wiring and such.

    I don’t resin print, but it looks like there is a missing layer or two. The ripples in the interface layers at the bed were confusing me at first, but that seems like it they were formed in the resin not being attached to anything. The rest of the print is failing at the same layers of those strange ripples.

    My guess would be a mechanical issue with the main Z screw, like there is something in that part of the thread that is causing it to lift a bit higher than it should. If it was completely loose, the rest of the print wouldn’t be viable.

    Clean the threads of the screw and try to replicate that error at those layers with a test print. Isolate the problem, is my advice.

    This part is really funky:




  • At 500yds with an AR, shooting in the general direction at a wide area is all you are doing anyway, bump stock or not. With a single shot, you might get the expected 1.5-2 MOA if you are exceptionally good. (That is a ~10 inch circle at 500yds.) Multiple shots? Maybe 50ft^2 area after the second and then rest are probably double that. The problem is recoil. While a proper stock helps, it’s not a magical solution for accuracy regardless of how the rifle is mounted. Even .223/5.56 is going to have recoil, especially during rapid fire.

    For me to get a consistent .25 MOA with my 25lb benchrest rifle takes a fuck ton of practice, lots of time between shots and self-loaded, custom and expensive cartridges that are tuned specifically for my barrel. (That would translate to accuracy of 1.25in at 500 yards.)

    Look. I didn’t want to get into this mess in this thread, but your perception of how these things work is inaccurate. I am not getting all hurr-durr-'murica-2A here as that is not the point and not my cup of tea anyway.

    If you are going to discuss these things, at least do it with the correct information.
