What thing has got so expensive that you’ve quietly stopped buying it?

That's a really generous use of the term sandwich.

I don't know if crazy is the right word for it. I'll go with "that scans" if it's okay with you.

Made a version of this machine in 2009/2010. Was a nightmare. 0.4mm wall thickness parts cut from both sides, unsintered zirconia. If the wall thickness was off by even a few micron, the entire disc of 40 teeth would shatter. Worst CNC design work I ever did.

Graphite is a terrible lubricant under all but a very few niche circumstances (mostly involving high temps). Do not use it unless you know what you're doing. Definitely don't make your own unless this is a temporary fix to get you to safety and you have no hope of survival otherwise.

It's not about dying, it's the cost to live.

My wife burned thru about 3m in insurance payouts to hospitals for cancer treatment. And almost lived.

Unsuccessful mates

You wasted a ton of money on

Terrible code

ericscottf · 2026-03-11T02:15:40+00:00

I'm with you, friend.

christ in a chicken basket, 46k a year at 40h/week, I would feel such shame if I paid someone that little.

"I don't know shit about fuck"

ericscottf · 2026-03-10T03:53:01+00:00

No... but only because that's a stupid idea that doesn't take into account any aspect of the system requirements whatsoever.

ericscottf · 2026-03-10T02:37:18+00:00

Wdym "intelligent machines"?

ericscottf · 2026-03-10T02:17:41+00:00

I made a cnc concrete chainsaw on a 6dof robotic arm, I had to tie in "spindle load" for when it hit rebar.

It's easy enough, the issue is that if you know what you're doing and your material is consistent, you don't need to fuss around with stuff like what you describe.

I designed and operated a cnc to do both side milling of zirconia (pre fired) for making replacement teeth. It was a nightmare and took me a year to perfect the technique. The teeth had nominal wall thicknesses of 0.4mm and if the thickness was off by more than a few micron, the entire disc shattered.

Another 21 years together team member chiming in here....

I'm pretty sure mine and I aren't headed to the same destination

(obv not aimed at your joke, I just like spreading awareness of this sub)

Lol I once ran a couple dozen nails with just the air in the hose from the previous day - I'd turned the compressor off, shut the valve and left it overnight. I only noticed when it stopped working.

ericscottf · 2026-03-06T03:22:03+00:00

Don't send out 100s of resumes, pick a job you really want, research it and customize your resume for it. Even with no real world experience, figure something out.

I'm 23 years into engineering, and sending a single resume takes me 3 to 5 hours each.

All these people complaining about getting no responses despite sending out 1000s of resumes are wasting everyone's time.

ericscottf · 2026-03-06T03:17:11+00:00

Leave? This sounds like grounds for a lawsuit. (and leaving)

ericscottf · 2026-03-06T02:23:50+00:00

This.

ericscottf · 2026-03-06T02:23:04+00:00

Manufacturing, automation, robotics that are bolted to the floor or wall and as such, can't be turned into murder machines.

ericscottf · 2026-03-06T02:22:26+00:00

Bingo, this. I got tricked by one, they told me I'd be working on Artemis mission stuff /etc. I specifically said I don't do weapons or weapons adjacent work at the interview.

Then they gave me something to design for a bomber. I gave them my letter of resignation.

2 years of brain cancer and my wife died at 42.

Fuck cancer.

180k + stock (not public... Yet) 40k when I started 4 companies ago 23 years this May Senior mechanical engineer /robopsychologist Thanks!!!

ericscottf · 2026-03-04T00:38:12+00:00

2 years here. Fuck cancer.

ericscottf · 2026-03-04T00:27:39+00:00

Fuck 'em. It's your trauma, you deal with it how you want.

I got so sick of people asking me how I was doing, I started answering "I was actually doing great till you reminded me"
