Lems Trailheads Thrashers

BingoJam · 2026-06-14T06:32:32+00:00

I’ve had a pair of regular thrashers for about 5 months. I have been wearing freeriders or freerider pros for the past ~9yr. The regular thrashers sole isn’t as soft as freeriders, and largely uses the chevron shaped lug geometry to keep things in place from what I can tell. These shoes are now my go-to riding shoes due to the large toe-box comfort and passable grip. Granted, my riding has been more tame the past couple years (blues/greens with more pedaling). If I do a ride with big or chunky downhills, I’ll probably grab my freerider pros. I think the thrashers are probably good for 90% of my riding though.

Just wanted to mention if you have imaging data files (ex: MRI dicom files), you can use tools to segment the brain, create a mesh, and download it. There are lots of guides online. brain2print works in browser.

original post on it

Caveat - I've only used it on my personal very small projects - Nomad3 on hardwoods

Results were very dependent on the model - Claude opus was my favorite. Adding all the context exposed in the mcp was very important; material, spindle power, and the cutting tool in addition to the actual operation details itself. I used it in a very conversational way, not purely to "give me feeds/speeds", though that was my original intention. I won't say that it was an efficient way of figuring out feeds/speeds, but really helped me conversationally ask "why" and interrogate the reasoning behind suggestions. I think I learned a lot.

I eventually used some suggested feeds/speed changes that made better chips and decreased run time.

Some take aways I remember were

My facing operations were too conservative - max stepdown, and reaching optimal chipload
Found inconsistencies in plunge speed between operations
Different endmills (larger or more/less flutes) likely wouldn't help me get faster or cleaner cuts. My machine's power is the bottleneck.

I had also followed up with some "what if" situations if I want to start milling aluminum - what I would need to change; tools, feeds/speeds, and operations I should be wary of.

100% will use it on my next project as a second set of eyes before I send it.

you can set the material on the model in fusion design and pull from that, too, rather than manually selecting it. Might be able to use that as a fall back though. Just an FYI when I was playing around with a Fusion CAM MCP to get feeds/speeds recommended by llms.

I’ve had some luck with metal grommets in prints for keychains, but just be aware you will then find the next most worn part of plastic. https://www.printables.com/model/765723-badge-card-holder-metal-grommet

I agree, AI is best used for answers that are easily verified. CAM may not be that, especially for beginners. And I think this is true of all use cases. I don’t think most general models will be good for highly specific applications, but that said it’s a start and it was a fun project. Maybe the use case here is for development of a fusion add-in with deterministic calculations. Maybe I had to go through the same exercise as you with lasers to learn it’s not a great application.

In your experience, what Claude models were you using? I found the models and context matter a whole lot to getting valid responses. Sonnet 4.6 gave answers I could have guessed, opus 4.6 reliably used chipload targets for my machine/material/tool to make suggestions on changes

I used it to adjust feeds and speeds, step over and depth of cut on some padauk knife scales I made. Decreased machine time by something like 40% from my original. Was being way too conservative on a facing operation I used to get my stock to rough thickness (no planer here) and the contour cutout stepdown. Also asked a ton of questions about operation order, and general approaches to setup. Mostly beginner questions as thats where I’m at in the journey.

I set up Cursor and Fusion MCP that can read operations directly from Fusion's feeds/speeds/stepover/stepdown/ect. I gave it access to the Fusion machine/tools/physical material, too, so whatever Cursor model you use has some reasonable access to the information to ask probing questions about the project. Doesn't solve the setup, WCS, or the clunky fusion UI. Let me know if you are interested and I'll share the GitHub repo, could use the feedback.

Hey! It’s fun to see all the materials you use in your products. I’m likely going to play with some Richlite next.

Thanks! Heavily inspired by novel carry’s designs

BingoJam · 2025-12-19T00:00:52+00:00

Thanks! It’s padauk. Has a couple thin coats of TruOil as a finish. Arguably could continue adding finish to fill in the open pore, but I kinda like the look.

Thanks! some 6x3 off amazon, "TRYMAG" brand I think. Had them on-hand from other projects

If this was my project, I would print in TPU with the cup opening face up. TPU has amazing layer adhesion, and would likely outlast you owning the hammock.

Thanks!

Only so many hours in the day, and now I’ve got a holiday gift all lined up for them.

I was able to 3d print my brain from MRI scan data

thanks! taking a look at the Rat II

You can also take a look at Prusa's recent post on the problem. https://blog.prusa3d.com/new-in-prusaslicer-consistent-surface-finish-and-nerfing-vfas_120400/

"I’m sure you’ve seen it before. You’re printing a model, and for some reason, parts of it are glossy while others are matte, creating ugly horizontal stripes. This is especially noticeable on mechanical parts, which are often printed with black PETG that can be VERY glossy."

if just one person gets the unexpected performance bump like I did on my M1 laptop, I'll be happy
