Surprised this hasn't been shared here before.

Built by my former colleague, Stewart Allen (Co-Founder/CTO of WebMethods, CTO of AddThis, Co-Founder/CPO of IonQ, et al.).

What caught my attention:

- 100% free, no subscriptions, no accounts, no cloud

- Local-first: all slicing and toolpath generation runs on your machine

- Works in any browser, even offline once loaded

- Supports FDM/SLA, CNC milling, laser cutting, wire EDM

- Fully open source: github.com/GridSpace/grid-apps

Refreshing to see a tool that isn't trying to lock you into a subscription or harvest your data.

Now if we can only get an offline printer…

Elegoo printers can be offline - you can run everything from the machine itself, as long as you have your model/s on a thumb drive. Or is that not what you mean?

I've used kiri:moto for several simple CNC projects!

This probably won't scroll to the correct place on the page but there's some images of my project at https://hcc.haus/propmania/#2024-palm-torches and https://static.cloudygo.com/static/Prop%20Making/2024%20Palm...

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.

More open source, browser-accessible tools is a good thing.

That said, aren't Prusa/Orca/etc. all already open-source (and part of the same lineage)?

They’re trying to introduce legislation that would require 3D printers to be online so that if you try to print a firearm, it won’t let you…

Granted, today, you can print offline.

Tomorrow? A firmware update might just brick it the next time it goes online or won’t be able to read the grbl

Same with Bambu's. They include microSD slots.

Am I weird in not being too surprised? It don't have experience with wire EDM but every toolpath generator or slicer I've ever used was just local software.

no shared lineage. Cura and Kiri started around the same time (2011/2012), but as completely separate projects. Cura is a C++ desktop app and Kiri has always been 100% browser-based (no cloud, all computation in the browser sandbox). the licenses are different, too. Cura/Prusa/Orca are GPL based and Kiri is MIT.
