PLA Ramen

The PLA not having been dried properly will cause this. Have you read the sticky on polymer extrusion?

Tim:  Any special considerations for the drill bit?  I'll throw some of these:  http://www.mcmaster.com/#2958a24/=t5lshy (and incremental larger sizes) into my upcoming order at McMaster.  I do want to setup the winder and get a read on what those diameters are before I drill the nozzle. 

@Titaniadioxide:
That's why I wanted to make sure that all the ABS was flushed out.  Took me longer than 2 hours.

Nipple rotating is a sign that the motor block needs to be moved back a bit or the main block moved forward.  The back end of the auger should not touch the hex socket, this will cause the nipple to rotate. 

The writer of Tim's 2nd link mentions going as low as "138-142" with PLA which is the only reason I felt comfortable doing it.

Grab a cheapo toaster oven for the pellets.  Then store the filament in a sealable container with desiccant.  I just did that to revive some purchased filament and rechargeable desiccant cartridges like what Revolve3D sells.  Amazon had 4 for $10-12.

Those are probably fine, but I use these:  30565A227

That is *a* sign, not the only sign. Another cause of nipple rotation is motor overload, like what happens when the polymer isn't hot enough to extrude.

He was using a different controller, and the only person to use that controller. 150C is about the lowest I'd go with PLA. Removing moisture is key. After that, running vertical/using a winder are helpful, I've heard. I almost never use PLA, so others have more experience than I.

Thanks a ton!  I'll make sure to dry off the pellets in an oven before we use it again.  Do you know of anything to store the pellets in that actually /is/ airtight?  It would be a lot more convenient to dry all the pellets and spend a bit of money on something that keeps the air and moisture out, than to bake the moisture off of each batch off before we use it. 

Also, is there something about the pellets that make them susceptible to the moisture, or will we have to do the same to any old prints we grind up to recycle?  Gut feeling is that PLA as a material itself is moisture-sucking, right?

Thanks for all the help!

That's insane.  It's that pissy and it's still one of the main 3D printing materials?  We'll look into some mason jars or other airtight containers.

Thanks!

I use "Iris Watertight totes" to store pellets, colorant, and filament. They work really well with some of the rechargeable desiccates inside. My first container for filament was a pet food storage bin made by iris which also worked well.

Oh man. Here we go again.

The title is "Polymer Extrusion - a brief tutorial". It covers much more than PLA extrusion, why would I name it PLA exclusively? It even talks about PLA extrusion and the need for PLA to be dry on the product page, which based on your bit about the melt filter nozzle, you didn't read much of. Here's the blurb right on the product page:

The website always displays the lowest cost variant. This is not a scam, the other available variants have clearly displayed prices. This is the way Shopify works, it is not something I can change in the store's settings. E3D hotends work the same way - bowden variants cost more than regular variants.

The text on the product page about the melt filter nozzle is not at the bottom, it is near the middle of the page, actually the top-middle. It is the 4th paragraph, out of 13 paragraphs. Your claim that it is near the bottom is entirely false.

I am not sure what you mean by "no option to buy the filter with the Filastruder". People do it all the time, about half of my customers. Your claim about this is also false.

There is nothing dirty about this "tactic". Shopify always displays the lowest variant's price, and there's no need to include melt filter nozzles when some folks have no use for them, as they run bigger printer nozzles (or use the Filastruder for things unrelated to 3D printing, of which I have several customers).

Spreading lies is not something I will tolerate. Your posting style is not constructive. Tell me this - how much of the product page did you read before purchasing?

It is not a lie, not a trick, not a tactic. It is how Shopify works - it always displays the lowest cost variant. Here, let me show you:

See there? $79.99. That is because the lowest cost E3Dv6 option costs 79.99.

The 3.0mm Bowden version costs $89.99. All prices are clearly displayed when the version is selected. The Filawinder comes in two versions - the PCB kit, and the full kit. It is not a trick, it is two versions of the same product. I have no option in Shopify to change this behavior.

On a 1920x1200 screen, only the first paragraph is visible. It is not reasonable to pack all relevant information into 4 lines of text. If you choose not to read the whole product page before making a purchase, I'm not sure what to tell you.

Yes i do find it more suitable for filawinder. As for E3D, i see no problem with it. I saw the picture an the price. When i ordered it and recieved it, it matched and no additional  (see below) hardware required to make it work properly.
By properly (for filastruder) i mean to extrude usable filament, not just extrude filament. Its a fine line that makes all the difference.
Filastruder absolutely needs to have filtered nozzle offered when selecting the size of the nozzle as well as offer an explanation as to why you should get it.

I dont know what you mean by "how Shopify works" Is this a pre-made website where you only get to edit small sections ?

In any event, i am not trying to score a $159 filawinder for $59 or get a free 1.75mm nozzle with filter. I really want the filawinder and i fixed the filter thing as i described in my $3.00 filter post as well as ordered one from another source for less so its no issues. Biggest problem is that someone else (another jerk like me) could run into the same problem as i have and start the same issues all over again.

I've not sold nearly as many as you have but i do lots of buying online. When i realized that filter was needed to extrude usable filament i got mad. When i saw the $59.99 to $159.99 switch on filawinder, i got even worse.

My fever is down now thanks to your price range specification on filawinder but still steaming over the filter and false hope of getting the filawinder for $59 Oh well, maybe one day or another place will emerge.

Thanks for taking action.

Oh yeah i know those. I hate them man. I had few websites of my own and never picked pre-made stuff. They just never seemed to work for me. Always had to design it my self so it would not only know how to change it but also how it works.
I dont code websites for anybody so i cant  help.

No need to include it in every kit, but users should get some IN YOUR FACE choice of getting one instead of stock one (for additional price just like the printed hopper/no hopper option you already have)
