e3d v6 installation problem with peek fan

[duvdev]

Hello,

I got my new e3d V6 kit today and I printed the:
e3d v6 lower plate and legs for stock layer fan.stl
and
e3d v6 upper plate.stl

from this link: http://repables.com/r/296/

Now the problem is after I connected it to rostock max v2 palte the peek fan mout can't fit in correctly.
you can see it in the pictures.

How can i solve that problem?

I had to use custom length standoffs between my platform and the hot-end mount.

I use the same printed objects, but without the towers built in. I use aluminum spacers from mcmaster carr (http://www.mcmaster.com/#93013a625/=tz7lvn)( Black-Finish Aluminum Unthreaded Spacer, 3/8" OD, 1-3/8" Length, #6 Screw Size)

[626Pilot]

My mount comes with a printable spacer that fits that fan (link in sig). Not that I use it myself. I mount it under the effector. Mounting it up top makes it harder to see what it's doing, and at least on my printer, encouraged jamming. Possibly a heat issue. When it's mounted below, there's nothing next to the hot end to trap any heat.

Also, it's not a PEEK fan. All metal hotends don't use PEEK

I've got my e3d v6 assembled and am trying to figure out all the next steps for an Orion. When you mount your hotend under the effector, doesn't that lose you a couple of inches of build height? That seems worth it if it's unreliable mounted above, but I'm trying to weigh that vs. others seeming to have success with it up top.

[jeffhuber]

teejaydub, i gained 10-20mm by installing the e3d over my stock hot end on the max v2. but mine is mounted above the plate... can you post a picture of what you mean?

[Captain Starfish]

There are two lengths of post commonly in use, it appears.

The longer one sits the heater block up into the middle of the effector platform and allows the fan shroud easy access. But the nozzle now sits higher and all the layer fan arrangements designed for the SeeMe hot end no longer work.

The shorter one (the one you and I have) sets the nozzle at the same height as the SeeMe one so the layer fans work, but the shroud doesn't correctly fit on the v6 of the E3D because now the bottom couple of vanes of the heatsink sit inside the effector ring. Presently I have the shroud sitting high, missing those two bottom fins, and I accept that is the reason I'm struggling with jamming at the end of a print.

At some point I really need to switch layer fan assembly and use the longer posts, or model and print a new heatsink shroud that dips into the effector platform central ring to get those two bottom fins.

I was talking about 626Pilot's approach - mounting the e3d under the effector:

Seems nice that way - you don't have to use posts at all, fan clearance is a non-issue, etc. - but it comes at a cost of a couple of inches of build space. Right?

[jeffhuber]

ah yes, completely right. mine is mounted above.

what does "unreliable" mean for mounted above?

[teejaydub]

Again from 626Pilot:

Mounting it up top makes it harder to see what it's doing, and at least on my printer, encouraged jamming. Possibly a heat issue. When it's mounted below, there's nothing next to the hot end to trap any heat.

This doesn't seem common, though, so I'm trying to decide which to do!

[jeffhuber]

I don't print PLA which seems to be the biggest culprit there. i print mainly with nylon and dont have any issues.

[626Pilot]

When you mount your hotend under the effector, doesn't that lose you a couple of inches of build height?

Yes, but it won't matter unless you're printing really tall stuff. Plus, it makes it way easier to see the filament being laid down. You may not need to mount it below, but I would even if I didn't have to.

Presently I have the shroud sitting high, missing those two bottom fins, and I accept that is the reason I'm struggling with jamming at the end of a print.

That'll do it. The bottom fin is by far the most important. It has to be as cool as possible.

[teejaydub]

Yes, but it won't matter unless you're printing really tall stuff.

I figure it doesn't matter unless what you want to print is more than ~7" and less than ~9" (on an Orion). Or, to view it another way, for things that you want to print as big as possible in one dimension, it reduces that dimension by over 20%.

I don't mean to be pedantic, I'm just mulling the pros and cons. Most of what I tend to print is small, but occasionally there's something - a short sword for my daughter's Halloween costume at the moment - where "as big as possible" is the operative dimension.

I've historically mounted my hot-ends above the effector platform like they come "stock", but I've recently been thinking about mounting my e3dv6 below the platform too... 626 does it with good results, Brian does it on the TL Nemesis... Less parts, less weight, less to flex and introduce variables.

I've never printed to the full extent of the machine's build volume, so losing a few inches is a moot point in my case.

I'll let you guys know if I switch up my setup. It will be interesting to see if there are any noticeable changes on my machine.

That brings up an interesting scenario. If you're printing something and your printer refuses to print a flat first layer (like mine) you may have problems printing large-footprint stuff, because one area of the surface is good but the other has the hot end too close to the surface. When layer #2 is put down, the excess filament from the first layer will knock the hot end around. Mounting above can give the hot end the ability to flex more, like a shock absorber. If you have this issue, mounting up top might be a good idea.

[Jimustanguitar]

I actually meant that it wouldn't hurt me to lose a few inches of build height I'm doing really well with the bed and first layer lately.

[REV]

I mounted the E3D below the effector platform, like 626pilot, and used his 'lucky number 7' blower fans. Doesn't really feel like I mounted those correctly, but that is beside the point.

Has anyone designed a revised heating fan that will cover all fins when the E3D is mounted above?
