New e3d v6 filament clicking/grinding filament

3D printing news - 18 min 14 sec ago

Everything went well with my anet until I thought about upgrading to bowden. I got the problem that the filament (1,75mm) hardly pushes throught the tube (tube=2mm diameter inside).Because of that I get a lot of underextrusion and missing layers. Im currently printing at 60mm/s. At 30mm/s it kinda works but not really better, it still doesnt extrude on some places. My extruder temp is 210C and I already cleaned everything and looked for a nozzle clog but everything is completely fine.Any suggestions?

Cheap Programming Laptop Canada

  • Total budget and country of purchase: Looking for <$500 CAD. Country of purchase is Canada (willing to look above this amount if necessary)

  • Do you prefer a 2 in 1 form factor, good battery life or best specifications for the money? Pick or include any that apply. I don't care about 2 in 1 form factor. Battery life is important as I will be using this laptop in class.

  • How important is weight and thinness to you? Lighter is better, but willing to sacrifice for price or battery life.

  • Which OS do you require? Windows, Mac, Chrome OS, Linux. Linux (so preloaded windows is fine, but will be removed after purchase)

  • Do you have a preferred screen size? If indifferent, put N/A. 13" / 15" (Current laptop is a chromebook with an 11" screen and I find it too small).

  • Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. No (I have a desktop that I use for gaming)

  • If you're gaming, do you have certain games you want to play? At what settings and FPS do you want? N/A

  • Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)? Needs to feel good to type on. Smooth trackpad is a plus.

Looking for a 15" law school laptop for a friend

* **Total budget and country of purchase:**

$2100 USA

* **Do you prefer a 2 in 1 form factor, good battery life or best specifications for the money?

Pick or include any that apply.**

Not want a 2 in 1 but a dedicated laptop. Touch screen for note-taking Best specs for the money.

Question:: Is an 8th gen i5 going to perform better than an 7th gen i7? or a 8th gen i7? (Yes, I'm confused because I'm not sure if the 8th gen is worthwhile for web browsing, word processing, research with a little netflix on the side.)

* **How important is weight and thinness to you?**

Don't care.

* **Which OS do you require? Windows, Mac, Chrome OS, Linux.**

Windows

* **Do you have a preferred screen size? If indifferent, put N/A.**

15"

* **Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run.**

Few games, no photo editing (movie and video streaming, though.)

* **If you're gaming, do you have certain games you want to play? At what settings and FPS do you want?** Nothing specific

* **Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)?**

Good input devices, yes: keyboard (not too shallow) Touch screen, touchpad, reliable build, good tech support

* **Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion.**

I was leaning towards a Dell XPS15 but am confused about the processors. The 8th gen gets pretty pricey with a touch screen. I'd love recommendations, though. Thank you all so much.

Can someone help me understand why some walls end up thicker than others?

3D printing news - 36 min 22 sec ago

Hi everybody, I'm at a loss as to why this is happening and I can't find anything on the internet, but this is a common problem with my 3d printing.

On the right is my 3d print of muzz64's Fish Fossilz and on the left is the approximate layer preview in Cura after slicing.

As you can part of the middle bit of the 3d print has fused along one wall but not the other - however in Cura they're the same distance apart/same wall thickness. This happens no matter where on the print bed I print and I'll see the same sorts of problems on other 3d prints when decent tolerances are needed.

If it was my Cura settings wouldn't I see the same happening in the layer preview? And wouldn't it affect both sides of the fish and not just one?

I'm really new to 3d printing - could someone help me out? :(

Cheers.

FYI I'm using an Ender 2, if that matters.

Reordering a list of tuples applying reordering rules to their second element

Learn Programming - 55 min 11 sec ago

Let's assume we have:

[('The', 'DET'), ('red', 'ADJ'), ('window', 'NOUN'), ('is', 'VERB'), ('closed', 'VERB'), ('.', 'PUNCT')]

It is a list of tuples such that their first element is a word of a sentence (in this case, 'The red window is closed.'), and the second its grammatical category (or tag).

Suppose we have the following rule:

  1. [('ADJ', 'NOUN'), ('NOUN', 'ADJ')]

This says that if we have an ADJ immediately followed by a NOUN (in this example, 'red', and 'window'), we should reorder them so that the NOUN is immediately followed by the ADJ. The result of applying rule 1 to the sentence would then be:

[('The', 'DET'), ('window', 'NOUN'), ('red', 'ADJ'), ('is', 'VERB'), ('closed', 'VERB'), ('.', 'PUNCT')]

Any one has an idea of how to automatize this for any number of other rules and sentences? Or even just some basic strategy would help, really.

Any help would be appreciated.

Please help! I need assistance with the electronics aspect of a DIY build

3D printing news - 55 min 36 sec ago

Ok, so I have a printer that had been shelved and I have one that works. I would really love to make the older one work, it's based upon a Prusa i3 but it's the Geeetech one, I have everything except the electronics. I have the stepper motors, the heat bed, the frame, the belts, the guide rods, auto level sensor, etc.

I don't have the PSU (but I can solve that one), the control board (I do have the A4988s), I would probably need new wiring if the CB will change and I have no clue how to plug it all in and program it all in once I get all the parts I want.

Secondly, I'd like to get as close to a Prusa quality as possible and we are looking at a budget of probably 100-200 (considering I already have 75%). Is this possible?

[Java] How to create a collection of objects with custom comparator?

Learn Programming - 57 min 21 sec ago

I am wanting to create a collection of objects and then implement some custom methods as well as sort this collection.

The objects I'm working with are playing cards, and I am wanting to create a "hand" of five cards and sort these by their rank. I would then want to compare two "hand" objects with each other to determine the winning hand. To accomplish this, I am thinking it would be best to create a "hand" object as well where I can implement these custom requirements. My confusion comes when I am trying to use the "card" object within the "hand" object.

The card object makes sense to me as there are two attributes each card has, being the "suite" and "rank". The hand's only attribute would be five "card" objects, so how do I represent this in the code? Am I approaching this the correct way?

Should I learn C/C++ before getting into iOS development?

iOS Programming - 1 hour 26 sec ago

I'm an intermediate developer and I know Java and Python decently well, I want to start making iOS apps and I hear Swift is a lot like the C languages. Would it be a good idea for me to jump right into Swift or learn the concepts of C first? thanks
