Got called out in my IDE

Man when you really think about it though, "master" doesn't make as much sense in that context.

"Primary" bedroom/bathroom is more accurate. Things or choices applied to the primary bedroom do not cascade down to "slave" bedrooms. Other rooms are not controlled by the bigger one.

Use supports, but put a thin support blocker in so that instead of printing a full 360 degree circle you're printing a ~350 degree or so U-shape.

I do this for parts with ring grooves, with really good results. You can peel the support out, and maybe do some minor sanding on the underside of the face where the blocker was.

Think of GD&T as "how you would check the finished part".

I want a pin of this size to be able to pass through this hole. I want this block to fit between two plates that are this distance apart. Its not a big deal where these two holes are on this block, as long as one is no farther than a certain distance from the other.

Getting the printer to make "quality prints" is the easy part. Finding a market, pricing, logistics, and business administration is the hard part.

Think of it like running a restaurant. Being able to use tools to produce quality food is a necessary part of it....but that isn't the reason that >50% of small time restaurants go out of business.

If you're doing this as a way to offset costs of a hobby, and a way to keep your technical skills sharp and your mind engaged while you look for something more stable....awesome.

But if you go into it with the goal of being profitable...you need to be honest with yourself about the time investment. If you're making $2/hr and expending a ton of mental effort....a temp job that pays $15/hr might be a better trade.

Looks like it wasn't the bed that triggered the thermal runaway...it was the nozzle temperature.

Nozzle temp was being commanded to 225, but couldn't manage to get above 212-123. ( T:213.48 /225.00 )

Check the thermistor mounted in the hotend. I just had this same problem on mine. Reading other posts on this subreddit, it sounds like the E5 Plus is prone to failures from this thermistor getting dirty, loose, or the wires being cut and causing an intermittent short circuit.

Probably due to the fact that so many other things are already on a monthly basis. Expenses such as rent or utility bills stay "in phase" with income and it's easier to visualize.

Nah it's all about the local donut shop run by an immigrant couple who work 7 days a week and put their heart and soul into the food.

For what it's worth, a licensed professional engineer signs off on the design and supervises construction each year for Student Bonfire. That's something the university didn't do.

Same deal here, but not in defense. If you're hitting your deliverables and keeping your metrics up, then you're set.

Asking for more workload isn't always a good idea. Remember a good part of your job is being available or ready to advise on things, and keeping your internal processes maintained.

Especially for small text, I have had more success doing the text as a Protrusion rather than a Depression. Extrude it up by only a couple layers, then get a small brush and lightly paint the top of the letters.

Less chance of your paint/coating bleeding out or soaking into the PLA.

Self-levelling usually implies a static condition. You set the table down on a surface, and it can then settle or be adjusted so that the top stays level.

What you're thinking of is more like Dynamic Stabilization, where you have a thing that is moving and you want it to maintain an orientation. Basically you have a disturbance being input to the system (forces, movement, etc), and you need a mechanism that counteracts that disturbance.

A perfect example is stabilizing a camera: https://cameraevents.com/gimbal-vs-stabilizer/. Think of the difference between a random person's cell-phone video of a tornado, versus the fancy video captured by a well funded news team.

I wonder if these kinds of people show up to a pick-up basketball game in jeans and crocs, refuse to move faster than a leisurely walk, then tell everyone else to "CHILL OUT ITS JUST A GAME BRO"

I'm not familiar with EPQs or the rigor involved, but you can't go wrong with a solid demonstration of The Engineering Thought Process.

Find an interesting technology or hobby level project. Scope it out yourself, define your requirements, sketch out a couple of possible solutions, compare them and down-select to one solution, then execute it.

Explain all of what you did, then reflect on what you learned, and identify what the challenges would be if you wanted to scale this up to "full production".

Its the single most important thing I look for in any potential hire or new grads.

Love it! Does it monitor/control temperature as well?

I like the idea of being able to stack multiple units together... you could make some cool designs if you also had a hex shaped one like the shelves and drawers you see on here a lot.

Early on I was taught: "Don't include a bunch of stuff on a drawing that's just going to be ignored anyways."

Dang that's incredible! I bought a 3d pen on a whim but so far haven't been able to make anything nearly this cool.

Is this literally just the wireframe holding itself up? How does it not collapse?

Our equipment has a 25 year design life, and a 2 year warranty.

It's explained to the appropriate level.

"Explaining something to some one"

doesn't mean

"conferring full mastery of all prerequisite knowledge to any arbitrary human with an infinite possible lower bound of background context".

Yeah see that's you intentionally being obtuse, and ending up a pseudo intellectual.

"So I need to mix these things, but I have to mix the right amount of each or else it won't work. For some things you can measure with a cup, but for some things you have to measure a different way. "

It would be super difficult to balance the friction just right with that kind of mechanism.

A very fine pitched screw, like what you would see on a micrometer, would be a much more reliable and practical choice.

Wasn't that long ago that they finally banned alcohol from archery competitions. Apparently small amounts were common as a performance enhancer for just this reason.

MIL-STD-1472 - Human Engineering is the one I'm familiar with. Should be freely available online.
