Siemen, less than a minute is fine for calculation, as long as it’s reliable. Bits, drills, material, and cutters cost more than computer time.
Password protected? Interesting, and not in a good way.

Fusion360 and done a lot of market penetration because it has CAM built in, unfortunately. It’s an arms-race for design solutions.

Aside from a large (400mm x 200mm x 1000mm ) 3D printer, I’ve been building a garden-variety CNC machine from recycled chip fabrication parts. I am actually further along than shown this video. I am sorry about my garage work-space, but when youtube demonitied all the small channels, it kept me from renting a proper space. Still, this is a low-buck operation. I put a lot of handwork building this thing.

And because this is a low-buck operation, spending a lot of money to generate tool paths is out of the question.

I have a few uses for the machine: I’ve done some speaker design and guitar making, and this machine is just big enough for that. While I have the chance, I am going to make some video equipment. I have some harmonic drives kicking around here, that would be good for an Arduino-controlled auto-panning rig. It seems like I am always needing little brackets for things, and this machine, as ugly as it is should be sturdy enough for milling aluminum, as long as the depth of cut isn’t too aggressive. I just need to get a spindle motor, but money is tight right now, as always.
I will check out that software after my guitar practice.
I wonder if there should be a front-end interface kit for Grasshopper projects.
