it doesn't make any sense. linux and the gpl have no technical reason to exist. one could've just bought a copy of unix, right? oh, some people couldn't afford unix, or wanted a bit more control about their own computers? "well that's a you problem" or what. remember the bill gates borg memes in the 1990s? remember "linux is a cancer"? but now it's totally fine to get assimilated by anthropic, which is the new microsoft btw. hello mcfly, anybody home?

reload STEP macro is also quite short. i put the STEP's path in the object's label (i'm sure there's a cleaner way).

svg to step is basically just:

with BuildPart() as p:
extrude(import_svg(sys.argv[1]), amount = 1)
export_step(p.part, sys.argv[2])

2026-07-09 18:36:00 UTC

i'm more comfy in inkscape than in freecad sketcher, but also i often need to import and replace step files in a freecad assembly, so i made two little scripts today that are super useful for my workflow: 1. conversion (extrusion) of an svg face (outline) to a 3D STEP file 2. reloading of imported STEP files in freecad so that the object stays at the same position + rotation as before

After we received CNC production samples, I sent out final detail changes for 2 of MNT Reform Next's 4 case parts to our CNC manufacturer and gave the green light for the first 90 aluminum cases. I wanted 2 corners on 2 of the parts to be smoothed off so that they don't become annoying to touch during heavy use. Here you can see Ana's updated corner design.

@nprofile…msjp after implementing most of the SNK-side PD state machine incl VDMs, my main issues stemmed from the timing and retry behavior of the first Source Capabilities message(s) that i have to send. this has to be done exactly right, and devices behave very differently in terms of how tolerant they are or how long they need to boot and respond (or don't respond anymore if they don't like a detail).
