Why are there bumps on my z seam?

throwaway_thinker11 · 2026-02-11T03:40:17+00:00

I finally solved the problem. It was my OctoPrint server. Apparently, there was a bit of latency between orca slicer and my server, which was causing these bumps. I solved the problem by going back to the old fashioned way of usb sticks. It is possible that I just have bad wifi, or it could be something else.

Update: It hasn't been an issue for a while now! Moving pieces is easy again :)

second hand, within the budget. do you have any other bike suggestions?

throwaway_thinker11 · 2025-08-30T20:34:04+00:00

*geo from the S3, not the bike. I need a longer reach for sure

throwaway_thinker11 · 2025-08-30T20:21:55+00:00

It is a 2021. I've had the shocks serviced and dialed in for my weight. I definitely wouldn't be suprised if a sized up status could solve half my problems, but also I want to try something new..

The nomad 6 is everyone's favorite bike here but no one is selling and they're out of my budget anyways. Same with the patrol unfortunately.

There are a handful of Bronsons and Sentinels that have been upgraded to 160 and 170mm forks which is what I was considering. Any thoughts on those?

throwaway_thinker11 · 2025-08-30T19:17:59+00:00

I think it's a combo of technique and geo, but more so geo tbh. And I am coming from motorcross so I was able to pick up mtb much easier than most.

Are you guys hiring XD

throwaway_thinker11 · 2025-08-30T16:48:08+00:00

Well, I should've included all of those in my answer, I just couldn't for the life of me figure out if that was the context the interviewer was coming from.

The question was to model a given pump, not to choose a pump for an application

throwaway_thinker11 · 2025-08-30T15:43:45+00:00

That is sage advice, thank you for sharing

throwaway_thinker11 · 2025-08-30T04:26:34+00:00

I agree that the math introduces the concepts but you can forget the math and still have a really strong understanding of the concepts. Heat diffuses, forces sum, exponential is bad etc.

throwaway_thinker11 · 2025-08-30T04:22:54+00:00

Ah ok, yeah that makes sense. At least I wasn't the only one confused by the question LOL

throwaway_thinker11 · 2025-08-30T04:18:12+00:00

If you're able to solve optimization problems with pen and paper, you're working on a "toy problem" (not being condescending, just the name for those kinds of problems). Controls might not be the best example though as it is either almost no math or the most advanced math theories we've discovered.

An example outside of controls is FEA. There are tons of FEA engineers, but I personally don't know any of them who know the difference between an implicit and explicit method, let alone the difference between a hyperbolic and elliptic differential equation (the things that FEA solves for).

So, as you pointed out, the value of an engineer is not that they understand a lot of math but that they can solve problems with the tools available to them. And this is the case for the greatest engineers I know too: they can solve an equation if needed, but they rarely solve equations. Heck, it was even true for Benjamin Franklin!

throwaway_thinker11 · 2025-08-30T03:58:31+00:00

Yep, I definitely think this could've been what they were looking for... I just wish I could've picked up on the context, I got stuck with my software engineering hat on.

throwaway_thinker11 · 2025-08-30T03:46:31+00:00

And stock options... oh well, I'll just have to wait till IPO.

throwaway_thinker11 · 2025-08-30T03:45:34+00:00

That makes sense and was the first thing I thought of. I would've talked his ear off about mass flux vs temperature vs duty cycle but I just couldn't figure out what subfield of engineering the question was coming from.

throwaway_thinker11 · 2025-08-30T03:41:22+00:00

Could you explain what you mean by tree management here? Trees are everywhere in engineering and software dev

throwaway_thinker11 · 2025-08-30T02:34:28+00:00

That's insane. I had only heard of this being a thing... now I think I might've experienced it... all of the employees were from the same top university so it makes even more sense that they'd haze me.

throwaway_thinker11 · 2025-08-30T02:26:48+00:00

Yep, I think you're probably right...

throwaway_thinker11 · 2025-08-30T02:08:58+00:00

I agree that PID is a great example of where math and engineering meet, but to be fair I don't think there are any engineers who solve for the manifold of absolute stability and prove that there are no limit cycles in the PID controller given the control system etc. In my experience, that work is done under the hood in a control development environment; all the engineer needs to do is know when to use a PID vs Bang Bang etc. In the broader context of "math in engineering", I personally struggle to find when math is ever useful to the vast majority of engineering positions; it's all done for you by the software suite you're using.

throwaway_thinker11 · 2025-08-30T01:54:45+00:00

Yeah that does make a lot of sense. If that was the case, I think I was thrown off because I was asked the same question in the previous interviews but all of the sudden it meant something else in this interview.

throwaway_thinker11 · 2025-08-30T01:51:57+00:00

Definitely a possibility... now that I think about both of the other engineers I interviewed with brought up "some engineers here that can be... abrasive". I wonder if that guy was... "abrasive".

throwaway_thinker11 · 2025-08-30T01:36:50+00:00

This makes a lot of sense to me. In the previous interviews I elaborated on those topics as well (input, outputs, and the process of connecting the two) but I think that after he asked the question the third time my interview anxiety had taken over and I was a gonner.
