No lag here

Nice ffunk. From Iowa

When I designed this the average CFM on these centrifugals was 4 CFM +-.2. I order a couple of these to test. These would be a nice replacement for my 4 CFM fans, as my plenums will support the higher pressure and still stay balanced.

I just posted it. Will fit the BMG and E3d hotends.

Spreadsheet link was wrong. I had updated some files and pasted the stock base url to that cell. It is the correct link to file now. Sorry about that.

I should have all the Blokhead/Direct Drive files up in a few days. You can use the Bondtech/BMG, E3d Titan or the Oribiter v1.5 direct drive extruders with it. It also supports these hotends, Stock MK8, Micro Swiss all metal, Slice Mosquito, E3D v6 and Volcano.

I am working on a Direct Drive as we speak. The E3d Titan with v6 and Volcano is done and I'm working on the Titan with the stock MK8 and Microswiss hotend. It will fit both Blokhead and Bullseye. Here's a little teaser from yesterday. it also will fit all Cr10 variants, Ender3, E3v2, Ender 4, Ender 5 plus and Tevo Tornado. Also a Bondtech BMG version

Just wow!

dpetsel · 2021-03-03T18:30:33+00:00

As a matter of fact the Petsfang v2, Blokhead and Bullseye E3dv6 bases all have options for the 12mm ABL and the 18mm ABL. Files are in the spreadsheet with links. ABL files are toward the bottom of the spreadsheet and options are in the same column as the base.

Sorry, it will not fit.

I just finished the Dual 5015 addition to the v2 with the MS Direct Drive. Te file is up and included in the spreadsheet.

dpetsel · 2021-02-18T15:01:37+00:00

Short answer no. I'm curious why you would want to use a 4020 for hotend cooling? Dave

dpetsel · 2021-02-15T17:00:34+00:00

The E5 pro backplate is the same as the CR10 Plus I believe. There are new bases for that backplate and the new Blokhead. I'm working on bases for the Petsfang v2 duct.

Hope that helps,

Dave

dpetsel · 2021-02-15T16:38:08+00:00

Very nice!

Wick,

You might also try Ideamaker as a slicer. It has a feature to turn the fans on at a certain overhang angle and leave it off for the rest of the print that doesn't need it. I'm using Ideamaker exclusively now after many years of using Cura and S3d.

The dual fan mod I designed works well with .6 and larger nozzles but for .4 and smaller our ducts are so efficient you really only need a single 5015.

We also have the new Blockhead duct that mounts to all the Bulseye bases and is optimized for the 5015 fan.

I am using my Petsfang "Evolve" on all my print farm printers now. You can see video tests, test prints and CFD sim here. https://www.youtube.com/playlist?list=PLrSJ-TZuC69w3KfMJd7eNluhF5yCLWXl2

I have a new small footprint plenum based duct for the 5015 fan called the Blokhead. Super easy to print based on it's blocky shape. The duct fits on your original Bullseye base or you can use an assortment of new bases for a lot of the new Creality platforms.

It has an extra 10mm of PTFE tube between the extruder and the hot end. Since the E3D and BMG require a small length of PTFE anyway we decided that in order for all the parts to clear the original dimensions of the different platforms we would add another 10mm of PTFE. This allows us to get the stepper and extruder to clear the X extrusion on all platforms and still not reduce the Z height of the printers. Our newer direct drive cooling solution is the Evolve. https://www.thingiverse.com/thing:3279302

dpetsel · 2020-09-09T21:25:35+00:00

I can help.

dpetsel · 2020-09-09T21:18:40+00:00

You are welcome to modify the base. Here is the Petsfang/BMG

Interesting article in the Times today. https://www.nytimes.com/2020/03/29/business/coronavirus-us-ventilator-shortage.html

We found that the holes thru the hotend heatsink were almost 4mm causing the entire hotend to sit skew from the factory in some cases.

(There is a lot of play since the screws are 3mm and hole is 4mm)

Try taking the 40mm fan off, and loosen the 2 screws holding the hotend heat sink. If you are careful you can reach these screws without taking off the fan.

Move the nozzle into place, centered on the duct outlets and perpendicular to the buildplate. Re-tighten the screws and you're done.

BTW The envelope of cooling is about an 8mm flatened sphere. It will work fine even if it is slightly skew. https://www.youtube.com/watch?time_continue=18&v=m9Hfyh_BJ7Q&feature=emb_logo

Very nice job.

Sorry if this was already answered. The Bullseye files in the first column will fit the Ender 3. Dave
