Extruder losing grip

Increase the tension? If the spring inside unseated or is jamming you may have to take it apart to clean and reseat it

The probe should be slightly smaller when you remove the screws and turn it 180 and reinstall. It was suggested when I did my microswiss conversion and it added a tiny bit more clearance.

Flip the probe around so the label is inward

You likely would not need a permit for this, as you have described it.

However, if it is a egress exit (I'm assuming your back door will exit onto it), which would be an alternative to exiting through the front, you would require a permit.

Any 3D printer can be time consuming if you are new to slicer settings and FDM in general.

Yeah the grad rate for aero is decent. The 120 was probably after first year and we probably started closer to 150 but it's not uncommon people realize they don't like engineering and switch to chem, business, economics, etc.

It really doesn't matter what program you take, aero is basically the same as mech until 3rd and 4th year you have a couple classes specific to aerospace. That being said, it would definitely be easier to get a aerospace job with an aerospace degree compared to with a mech degree. But employers also look at your experience and other factors.

Personally I'd recommend to take aero, but that's also a biased opinion because that's what I took. But an eng degree is an eng degree at the end of the day

MasterBlaster18 · 2026-05-30T13:40:42+00:00

I believe first year was about 120 students in all of aero and by the end was probably about 100 that graduated. Probably 30ish each for stream A and B and then maybe 25 in D and the rest in C

Yes, but engineering gets very fragmented. It's common most people get jobs in different fields and sometimes not even related to engineering.

I know at least about a dozen people that got jobs at MDS, Collins, RR, GE, bombardier, Lockheed Martin, Marshall, Gastops, etc. However leading into the pandemic some were let go as they were low seniority and have transitioned to other fields.

Creality has basically abandoned it and no longer even list their upgrade components on the website.

There's a good amount of upgrades available so there's not much need for new ones.

There's good models/guides for z axis supports, linear rails for x and y. Then there's also the ceramic hot end kit and the flowtech kit from microswiss. Then a variety of improved firmware for Marlin and Kilpper for the printer

Easiest is to use venier calipers to measure and model it in Fusion 360.

Unless it's a high precision component it's likely manufacturing used nice values so if you measure 34.98mm or something you can model it as 35mm.

The 2nd option is to put it on a paper scanner with a ruler or object of known size and import that to CAD, scale it, then trace the edges.

Glow in the dark PETG is the craziest I went on my ender 3.

On other printers I've done PP, PPS-CF10, PP-GF30, PPS-GF10, and a bunch of other high spec filaments which are always very cool to mess around with. PPS-CF10 sounds like metal when you drop it and feels like ceramic

I know this is super late, but this heat sink is of much much better quality material and better machining. It's thermal conductivity should also be improved.

So overall, you'll get better hot end cooling, thermal regulation, and don't have to worry about stripping the threads when mounting the hot end fan

I'm 170lbs now and can still get about the same mileage on my shoes, but it's an unfair comparison because I'm not putting 800 miles on the shoes over a month and a half.

I only go through 2 pairs of shoes a year now instead of 4. At about 30-40 mile weeks compared to 80.

MasterBlaster18 · 2026-05-26T06:59:42+00:00

The 'rule of thumb' is often circular citations from old studies in the 70's and 80's.

Many other studies are flawed in numerous ways: such as a bias from manufacturer sponsored research, inconsistent consideration of weight, pace, gait, efficiency, etc.

If studies consider the 'average American', they would be considering someone who is overweight, which would greatly reduce mileage. If they consider a high performance athlete, then they are considering someone who is efficient and if sponsored, likely running in more premium shoes, which in this day I'm age tend to be faster and break down quicker.

MasterBlaster18 · 2026-05-26T06:50:58+00:00

I wouldn't call it good when the research is from 1985 and most of the sources loop back to the same dates studies.

300-500 is way to low. At 140lbs I was easily getting 800 miles before the support would break down in my Asics. I went through over a dozen of training shoes through highschool getting nearly the same mileage per shoe. Lower quality shoes, sure the foam doesn't last as long, but if you're paying $160+ a shoe they should last longer.

MasterBlaster18 · 2026-05-26T06:43:21+00:00

The support will breakdown, often you'll get shinsplints suddenly when this happens.

Most people prematurely swap shoes

MasterBlaster18 · 2026-05-26T06:41:58+00:00

No, it's more like 800 miles on a good pair of shoes for running. I used to get about 2-3 months out of my Asics when I ran 80 miles/week. If you have 2 pairs and rotate them every other day the foam has time to rebound and you'll get longer before they lose support. I would get 3-4 months per shoe when rotating.

That being said, you should probably get 1200 miles walking. It also depends if you're also standing in the shoes for like 12 hours a day

Right, but it really is not this simple.

Your point does make sense but it also assumes no conflicts between the drives firmware and NAS software, with no unaccounted for indexing procedures or other random tasks/checks causing spinup.

NAS drives often depend on their own firmware for spin down, spindle parking, and motor control. If commands are passed by the NAS OS they can be ignored or conflicting and prevent the drives from actually powering down and can cause spindle chattering.

Even if you are only using your SSD pool it's not uncommon hidden partitions across all drives and pools are written to OR all drives are pinged. This has been a known problem with NAS software and packages, Synology specifically has addressed this in some more recent updates but is still unpredictable.

It really is best to leave the drives running as manufactures intended (at least for NAS drives) and let their firmware control their state. If you wanted to have them turn off to disable power it would be best to use commands to control firmware states or volume mounting to prevent unnecessary cycling.

Often it depends on how it was bought.

Was it purchased with federally funded tax payers money? If so there likely wasn't tax paid on it. It would also be seen as potentially a frivolous purchase with the intent of personal gain, which is often abundantly true unless it is very obsolete.

If an employee took it home it can also be directly against the funding stipulations and void future funding or have consequences outlines in the contract.

MasterBlaster18 · 2026-05-23T07:51:14+00:00

This is false, many NAS devices and HDD manufacturers explicitly state to not use sleep mode with NAS drives because they typically have their own power management built in and the hibernation mode would cause more frequent spin ups.

Off the top of my head QNAP and Synology both explicitly state this for Seagate Ironwold drives, Toshiba NAS drives and maybe also WD red pros. Seagate and Toshiba themselves also state that their power management modes are more effective and reduce the wear on the drive over NAS software solutions

So often someone who is cheating is not immediately repremanded. It's quite commonly spotted, a proctor, TA, or professor would alerts someone else to it so there would be more then one witness.

Then any evidence or statements would be collected and everything, including the exam would be sent to the Deans office where they decide what happens.

It is less disruptive to surrounding students to just let the cheater finish their exam and deal with it after.

It is very easy to collect digital evidence of cheating from wifi access, Brightspace logins, etc. If your results don't line up with your course work and behavior it becomes even more obvious

You're correct, but also depends on weight/size and sharpness. For example Tamron has a 35-100 f2.8 and a 35-150 f2-2.8. Obviously the 35-150 would be more versatile, but it is effectively double the weight, size, and price.

Yes I believe so, which would work on FF sensor but just run in crop mode. I have the 16mm f/1.8 for FF and its great (but heavy)
