Those with an E3D V6, which layer fan design do you use?

shentheory · Post by **shentheory** » Tue Dec 02, 2014 9:01 pm

I am mounting it with the EZ Groove Mount Adaptor, So even better if you use that. I thought that the layer fan design from the manual would work, but I've read a few posts that give me some doubts, tho I'm not 100% sure.

Much appreciated!

For mounting above the platform, I have found these two designs:

http://repables.com/r/399/

Thanks for the files.
One of them really stands out as the one I want to try.

I made repables 399 because of low clearance. I used the standard setup with 40mm standoffs to clear the PEEK fan (what do you call it when there isn't PEEK?) which made the clearance beneath the platform much lower. I think my duct on Repables clears a 9mm gap.

I've been meaning to update that design.... I've learned a lot about 3D modeling since then.

Jim, if you do update the design would you let us know?

Will do!

Dang those are massive!!

I wonder what kind of mount/effector that is to let it be mounted below??

They are not as massive as they appear in the photograph.
They are designed to fit under a normal effector.

Ah nice! And I meant for the Hotend to be mounted below the effector like that. Seems cool!!

Jim any chance you could upload the raw file and the program you drew it up in?

I was just getting ready to draw one up myself would save reinventing the wheel. I just want to modify the height.

Seems another part of the puzzle for my E3D hot end jamming might be the layer fan is blowing to much onto the nozzle and cooling it down.
I modified the original with a belt sander which was quick and works but might be causing problems since it opened up the entire bottom.

Thanks,
Pete

I drew it in FreeCad 0.14 - Source file has been uploaded...

I must warn you that I did a terrible job drawing it

I was fighting with FreeCad the whole time and barely pulled it off because I kept breaking the model every time I added a new feature. Now I've taught myself DesignSpark Mechanical, and that software works much much better with my brain - that's why I want to draw it up again.

I'll try to do that this weekend and upload a less janky version with improvements.

What's the consensus on source filetypes? Obviously an FCstd file is not friendly to most people, and an STL is not easily edited (BTW check out the Cleanup3 extension in Scatsup for recovering STL files!)...

STEP or IGES are good "portable" model formats.

Be sure to keep inches and mm separate. I sent a STEP file to a mold maker and he called me saying they couldn't do features that small. Small? Turns out they were reading mm while I had sent inches.

Had that the first time I loaded an STL into MatterControl, there was a tiny little small infinitesimal speck shown in the preview. Oh, THAT problem AGAIN.

Why don't people store UNITS in their file headers?!?!

Umm because STL doesn't store units. So you just have to multiply by 25.4 if you work in inches.

So it's a 1 way problem that only exists if you START with inches?
Why can't we just switch to metric already?

+1 to that

Hence my lament of why not? It's ONE byte in a header. Or if someone had wanted to get really fancy you could give a ratio to mm so I could use furlongs if I wanted to.

[rant]
As to why not use mm, my CNC milling machine speaks inches along with my manual mill and lathe. Almost all my clients look at me cross-eyed when I speak mystical metric. The raw materials I buy are mostly in inch. Metric tools cost WAY more than inch ones here.

We as in the whole country. It's not easy, but we are the oddballs.

Just wait until someone starts telling you layer height in inches. How many thou?

I love how "thou" is a unit to a lot of people. They couldn't tell you what it equates to or what the name implies, it's just "a thou!"

Bam! Right in the heart...
I've been using my American dial indicator to calculate steps per mm

It bothered me enough on my motorcycles to buy a "real" set of metric feeler gauges, but I haven't dropped the dollars on a metric dial yet.

bot · Post by **bot** » Thu Dec 04, 2014 4:36 pm

How many steps per yard are you running?

precisionpete · Post by **precisionpete** » Thu Dec 04, 2014 9:57 pm

Getting off topic but those of you who are old enough back when they tried to teach us all metric in school. How did that work out?

And the fun thing which is my pet peeve, I get drawings which have both mm and inches

Who does that?

Yes captain we are not in Kansas and we WILL crash.
