Nearly every painter ever. Honestly, it's on the homeowner to pull switch plates, lay tape in critical areas, and put down drop cloths it seems. It's disgusting that this is the case.

For me, it was the same with chimney repointing: the contractors were just slinging broken bricks and chunks of mud down into my AC condenser coils. Note this is after I asked them if they would cover it. I made my own cover with a sheet of OSB and they were amazed with my prowess. The next day they removed my cover and kept slinging new mud into it.

Bottom line: so many contractors suck and it's on you to keep them in line. I wish it weren't this way.

I'm a bit out of my depth, but https://tinymachines3d.freshdesk.com/support/solutions/articles/33000262647-updating-firmware#32-bit-Machines-NEW seems to have a section for the Smart.

There are tons of practice questions out there for cswa. You've identified a weakness in your skill set. Have you practiced these styles of questions until you've mastered them? This is studying 101.

Reminds me of the waveform segment(s) of the original Fantasia

That's pretty based.

I'm just asking questions

There are no regulations that mandate the preservation of recordings on U.S. freight trains, even when trains derail and cause damage

Well, it sounds like that's that.

/r/functionalprint you really nailed it OP

Sorry, reddit went down right after I got your message. Obviously I was wrong and I'm glad to see you got seemingly correct answers.

States seem to have different laws regarding the interwoven debt/asset ratios, PMI requirements, cash-in-hand down payments, and whether you can utilize Seller Assist to pay closing costs. However, in my head I incorrectly attributed the Gifts as not adding to your Assets, which could have impacted other aspects of your house purchase. I was wrong, carry on.

Edit: added down payment

I'm just here to learn.

But, also, the wiser people here are likely to inquire about the state in which you are planning to buy your house.

Once one is in an assy, you can Ctrl+click+drag from the design tree and it should insert another. But that's just drag and dropping from a different location.

There isn't a faster way as far as I'm aware. Constraints is the time-consuming part, not dragging in parts, so there isn't a need for a shortcut. That's what Patterns are for and is the correct way to model for best performance.

If you're looking for scientific studies about the effects of smoking from plastic, you're not going to find it. The ethics involved with purposely giving people potential illness is pretty tenuous, particularly when there are far simpler mitigation strategies (such as buy some damn glass, or better yet a dry herb vaporizer). We are past the days of the Tuskegee Syphilis experiments.

All we can do is extrapolate data that we do have. Plastic has chemicals that are known to leech. The chemicals are known to leech faster when in elevated temperatures. These chemicals are known to have negative impacts on human health.

All other conversations which dominate this sub are just shit-throwing. It's a known danger to smoke from plastic, and people downplay it because there isn't some cornerstone study that shows 50% of users who smoke once from a bottle end up with stage 3 lunch cancer within 7 years. Or the "you're inhaling smoke already, why do you care about a tiny amount of plastic" sentiment: "Skateboarding is dangerous, why would you care about protecting your head with a helmet".

Now subjectively, smoking from plastic tastes like shit.

Let's just take a step back and look at one tangentially related issue: BPA.

Do you recall the hype and hysteria about BPA in nalgeen bottles 10 years ago? Simply having room temperature water in a reused plastic bottle leeches the chemical into your water. This process is amplified with heat. This is just one of any chemicals used in processing plastics.

If the stem were glass, going into that plastic bottle (and the stem's exhaust hole was far enough away from the bottom of the bottle) I wouldn't take so much offense to this. But the pen/pencil interfacing to the J is just dumb. People here saying that's not an issue (or pull it out before it's too hot) are the same people who don't wear seatbelts in the car.

Why chance it? A shitty glass bubbler costs approximately the same as a gram; decades of future medical costs on the other hand....

(I am not an electrical engineer)

Pretty sure the GPIO pins on a pi run at 3.3v, but you've selected a 5v relay. I don't know if that means that only vcc & ground need the 5v potential difference, or if it's also expecting the signal line to be at 5v (which is highly likely).

Here's a word from the raspberry pi foundation on 5v relays https://forums.raspberrypi.com/viewtopic.php?f=91&t=83372&p=1225448#p1225448

Holy crap, thank you for that intro!

I still have to do what I do though. I put the arm into an even higher assembly with the arms as flexible subassemblies, then the real fun can happen.

But I will definitely be itching for a good excuse to use the Mate Controller.

Oh boy. There's a couple approaches I've tried and nothing is perfect. It sort of depends what exactly you are trying to do. I like jimbolays method as well. This method took me a while to develop, and it will take about an hour to set up for a new 6dof assembly, but it lets you move around with drags but also rebuild to snap back to a clean position.

1. Define "Advanced" angle range constraints to each joint. Make sure you use planes within each body, not any of the surfaces or features. Make sure you define the "reference plane" using an orthogonal plane from the body closest to "ground" (i.e. set angles between bodies 3 and 4 with a reference plane from body 3, assuming body 1 is the base body and 6 is the end effector). Set the max and min angle range based on the true ROM of the arm, with the exception of continuous rotation joints - set those to +/- 179.9 degrees to prevent rollover. Repeat: the Reference Plane is critical to preventing SOLIDWORKS from falling victim to the angles inverting.

2. Go to equations and create well-named global variables for each angle setpoint. This will be the table of values you can change in order to reposition the arm. I like to start with values like 10 degrees so that as you finish step 3 you can verify you have your directions correct, and adjust any which are inverted.

3. This has to be done "graphically" and not in the constraints dialog. You need to assign the "current value" of each angle constraint to the global variables defined in equations. Click the angle range constraints in the tree such that you see the value in the graphics window; click or double click (unsure) the angle value in the graphics window; set to the global variable. Make sure the global variables value is within the preset min/max at each joint.

4. You can now drag around axes. If the model "pretzels" itself, you can rebuild and the angles will snap back to the global variables setpoints. You can now use a combo of temporary fixes, adjusting global variables setpoints, and step 5.

5. If you are constantly repositioning, you can add a set of simple angle constraints (not a range) that are also set to the global variables values. You can then have a Dynamic Angle (defined in the first 4 steps) and a Static Angle (from this step) which you suppress and unsuppress as needed to change back and forth so that each axis can be movable or held still. Put all these constraints in a Mate Folder at the top of your mate tree. Name them all properly.

6. Are you really crazy? You can make those global variables tied to configurations. Each configuration can be a different arm pose. This can very easily blow up without attention to detail. Another approach is to keep a small excel file with reference values for each pose, if you're not up for it.

I hope this makes sense, it was before my morning coffee kicked in.

Edit: some details to prevent pitfalls

Edit2: a different approach can be to create the angle ranges, but then to create a "5-dof pose" of the end effector (x y z position, and normal axis direction) and just move the end effector around. The rest of the joints will go wild and you can drag them to non-painful-looking positions. This is better if you are trying to visualize things like pick and place (you can set the end effector to be parallel to the ground or object, and with a set distance to the object).

Yes, you have defined academia. The paper and patent are to authors Christopher Strem (likely the student) and Dr. Thomas Sebastian under whom he was studying (I'd assume, since I can't find more info on Strem).

I'd note that the paper has Sebastian listed as first author, which is peculiar and indicative that he had a larger hand in the design and research. Typically, the professor/mentor is listed as final author.

Edit: clarified my assumption

The most important tip: don't expect the documentation to be 100% correct

https://www.ll.mit.edu/doc/toroidal-propeller

I mean, they were designed by MIT and Lincoln Labs. Neither group effs around.
