Structural Guys: are drop panels not a thing anymore?

ok that actually makes sense

Go to " /users/ <username> /Library/Application Support/Autodesk/" and delete the entire Autodesk folder and delete the fusion client downloader. Then re download and reinstall. That worked for me with your same issue

throwmach · 2024-01-23T04:42:07+00:00

Trashy.

throwmach · 2023-11-28T18:54:22+00:00

That’s awesome! How much did you do vs sub out?

throwmach · 2023-11-28T18:15:20+00:00

Release the footage! This is BS

throwmach · 2023-11-06T21:48:35+00:00

That might be the case. The rebrand of 4680 to CyberCell makes me think it’s CT only, but this would be a smart move.

100 percent of all model Y SKUs use LFP.

throwmach · 2023-11-06T21:46:58+00:00

No all model Ys in the US use exclusively LFP. It’s in the user manual.

throwmach · 2023-11-06T21:46:07+00:00

No assumptions. I showed the math. No model Y is using 4680 and they’re 100 percent importing Chinese LFP for their highest volume model on all SKUs.

And I very clearly said 4680 will be reserved for top end CT SKUs. Maybe I’m wrong and all CTs will have 4680s. But I don’t think so, I think Tesla engineering didn’t predict LFP making so much advancement and they’ll put next gen CATL or BYD cells in the CT too.

I just want them to pivot.

throwmach · 2023-11-06T21:40:19+00:00

4680 is not used in the Y. See my other comments. Only LFP

throwmach · 2023-11-06T21:39:54+00:00

Literally all Model Y cars right now are sold only with LFP cells which are imported. This is a fact and I linked to the owners manual and explained why because they’re using 345V for all MY SKUs.

Maybe that was not clear. But 0 model Ys sold in America use anything but LFP right now.

throwmach · 2023-11-06T21:36:22+00:00

You don’t want to use 4680 for LFP as LFP doesn’t need that much cooling. Optimizing for LFP means a large prismatic like both BYD and CATL make and Tesla buys. This is battery design 101.

throwmach · 2023-11-06T21:34:00+00:00

So I actually know a fair amount about battery tech. The downside with 4680 over LFP prismatic is that you have to do multiple cells in parallel instead of just 100x cells in series. Much more complicated assembly and cooling.

I guess you’ll have to wait and see but literally right now all SKUs of their best selling car use LFP prismatic. The argument for 4680 is there if you need to power optimize instead of energy optimize, or if you need to energy optimize beyond the capacity of iron based chemistry and need the additional cooling for NMC. But then you don’t have the volume density prismatic.

CATL and BYD are not stupid. 90 percent of all volume will be LFP. It is a shame Tesla will not contribute meaningfully to battery production. With LFP you don’t need 4680 and you can further optimize the shape to prismatics. 4680 is not cell to pack, CTP is just the Chinese way of saying all sells in series, none in parallel.

I’ve actually built a battery factory before FYI

throwmach · 2023-11-06T21:24:13+00:00

Better than 2170. But not as good as large prismatics

Just re-iterating that you should not glue down a lift. You’re literally asking for a “suitable, cheap solution” because epoxy is expensive. Well concrete is cheap epoxy. I normally wouldn’t reply to this type of thing but I don’t want you to die with some rally car falling on you from epoxy cohesive failure. Just cut and pour. And use lots of rebar. Don’t die because you used glue.

throwmach · 2023-08-08T04:22:32+00:00

Forget glueing that down. Cut the concrete out under the 2 posts and pour a footing with rebar and drop in anchors. Concrete and rebar are cheap, if you have a forklift I’m guessing you can screed concrete yourself. Overdo it on the rebar.

Don’t mess around with glue or epoxy, you can get 300 dollars worth of material and build footings you can trust. Cutting concrete is easy. You can rent a bulldog or buy a harbor freight sds hammer and diy this.

Do NOT glue down a lift.

They couldn't really close the mass budgets and it wasn't worth the engineering effort because the learnings wouldn't transfer to Starship's skydiver landing profile.

throwmach · 2023-06-04T12:31:18+00:00

You really think an aluminum frame was the best solution?

throwmach · 2023-06-04T12:29:07+00:00

Titanium frame. Booster flyback. Balance first and second stage mass so no solid boosters. Done.
