The bottom panel is hdpe currently and "trayed", but you wouldn't run this machine with flood coolant anyway. mql might work but the idea was to cut dry, suck away chips and rely on coated end mills. I've seen people exp

I designed a little machine that's smaller than the Carvera with a 300W spindle at a lower price-point but requiring DIY (my build is probably around $550-600 now), I kept it smaller for a couple of reasons but stiffness was one of the

Good point - there is a provision for laser-cut steel or alu plates that sit inside pockets inside the enclosure panels as I figured many would be turned off by a full plywood design. The metal parts are symmetric so you can cut 2x of each

Documentation is definitely lacking - I just got the design to a point where I'm pretty happy with it. So far only 1 machine exists and the build has a few bits that are... less than ideal. The plan was to build a second machine and op

I tried [1] - replaced the sides with 2040s, blind-jointed every extrusion, replaced X with MGN12H + 4 carriages, replaced the whole Z with 4080U and even bolted it into an MDF box to stiffen it up. The 3018 could cut alu, but not well. May

It is definitely more expensive than 3d printing in terms of consumables but china/aliexpress has really good hobby-quality equipment now - if you don't mind the country of origin. Many of their coated end-mills are decent and &lt

Shameless plug if anyone is interested - I'm working on a $600-ish open-source, reasonably capable, but small and somewhat "tidy" hobby CNC machine with BOM cost around $600 that requires some DIYing. It's meant to be an

Too little, too late? I haven't rented in SF in a while but I imagine these would have done well 5-6 years ago. Afair, I've heard of the company before so that's probably how long they were caught up regulatory purgatory.

Ask HN: Labor Productivity as a measure of impact of gen AI?

I was thinking of an objective measure of the impact of GenAI on society - labor productivity seemed like possibly one decent measure. Gen AI and esp. ChatGPT has been mainstream for around a year and very popular for at least 6 months (rea

I saw as more of a "look, this can be done without impacting speed - Apple, just do it" kind of video. Which is why I thought they didn't speak to the how.

That seems to be often the pitfall with socialism-within-capitalism as often done in California imo - many of these socialist-ish policies only work if there's no easy "escape hatch" or it's at least uncommon. But not ha

The claim was about _full_ driving being anything but, ie not _fully_ self-driving, not being completely fake. Disengaging every 10-110 miles is just not "full", it's partial. And then the gp went into details in which speci

I think this is valid though. Transformer models don't explicitly do logic but implicitly "vibe" out the answer from the input sequence (using the attention mechanism) and learnt knowledge - they're predicting text seque

The general opinion here on HN seems to be that the most talented that can easily land a new job are the first to leave - might be a good time to skim the cream of the crop, even if for 12-18 months. Who knows, many might even stay when eve

If AI were to plateau, OpenAI would be one of many providers without a clear edge, they'd lose market share. Companies might even start competing on price. Imo, it's not clear any of the software providers would really do that wel

Part of the earlier appeal of YC was that it was a batch of approval that, at least imo, was a strong signal to VCs to take a good look at the company and more-likely-than-not invest in. With larger batches and more lax selection that signa

Most of the (federal) tax money goes to Social Securiy + Medicare/aid, servicing interest and funding the military, probably 60-70% afair. It's hardly "pay[ing] their elite friends for things you’ll never see"?
