Surprised this hasn't been shared here before.<p>Built by my former colleague, Stewart Allen (Co-Founder/CTO of WebMethods, CTO of AddThis, Co-Founder/CPO of IonQ, et al.).<p>What caught my attention:<p>- 100% free, no subscriptions, no accounts, no cloud<p>- Local-first: all slicing and toolpath generation runs on your machine<p>- Works in any browser, even offline once loaded<p>- Supports FDM/SLA, CNC milling, laser cutting, wire EDM<p>- Fully open source: github.com/GridSpace/grid-apps<p>Refreshing to see a tool that isn't trying to lock you into a subscription or harvest your data.

OT: Why is that Alphabet, Mozilla, Apple, etc can get together to create web standards that allow anyone to create software that works cross-platform - only a browser is needed, but Microsoft, Alphabet, Apple, Canonical, etc can't get together to create standards that allow anyone to create software that works cross-platform?

I've used kiri:moto for several simple CNC projects!<p>This probably won't scroll to the correct place on the page but there's some images of my project at <a href="https://hcc.haus/propmania/#2024-palm-torches" rel="nofollow">https://hcc.haus/propmania/#2024-palm-torches</a> and <a href="https://static.cloudygo.com/static/Prop%20Making/2024%20Palm%20Torch%20-%20Complete%20Blank.jpg" rel="nofollow">https://static.cloudygo.com/static/Prop%20Making/2024%20Palm...</a><p>I used it instead of the terrible closed source Easel App for a CARVEY hobby CNC. For metal milling I find Fusion 360 is necessary.

This looks great. I was hoping it would have been a good OrcaSlicer replacement for my FDM printer, but unfortunately it didn't generate any top surfaces (except for the topmost one) for a model I imported in. I didn't know if it was the printer profile (Creality.Ender3) or something else, but it seems I'm still using OrcaSlicer for the time being.

More open source, browser-accessible tools is a good thing.<p>That said, aren't Prusa/Orca/etc. all already open-source (and part of the same lineage)?

Great tool for a Makerspace - really appreciate the ability to use the same tool for laser cutting, 3d printing, and CNC. These are big jumps for people typically - having a familiar tool would help people transition from one area to another.

Now if we can only get an offline printer…
