Fidget toy test with UFO duct
Checking finished part's fitment. Quality is not that great, but it was moving pretty fast. Flow was a bit too high.

www.printables.com/model/985942-spiral-passthrough-fidget Testing the UFO duct. This is interesting! With this duct and this model, 10% fan... I had it set to my normal 35% fan @ .7s min layer time, and the layers separate. Move down to 15%, increase temp to 285 and bingo. 700mms/30K acceleration/60SCV/ABS/285C ua-cam.com/video/XFG1Eomm_OM/v-deo.html

This is one of many tests I use to see the cooling performance. This is called a Shrunken overhang test: www.thingiverse.com/thing:6315375 VaLvNaToR can do this in ~2:30 and have been as low as 2:15, see other video on this channel. So that is my reference, for this test, in comparison. This one was 2:38!!! I went to the 8 orifice in order to get more volume. The 4 hole was in the range of ~60G...
REV-2 UFO Duct
Переглядів 29021 день тому
One problem left, that nasty pressure in the front. I believe the issue is the forward mass, under higher fan speed, is not allowed to spread over. When the duct volume is complete filled, and makes pressure instead of velocity, the air has no place to go and overruns the front valve outlet slit. Not sure I can fix without CFD or a lot of trial and error. The air is getting more controlled and ...
New duct design, Take 1

9 min benchy test with new duct. Test the duct slow first so I don't get my hopes up. There are some issues on the start of the roof, small, but there. Need to make an angle change more downward. Impressed for a 1st iteration, hope it get's better. This is an old file, not sure the acceleration. 500mms, maybe 30K, 20-50SCV, can't remember. Tops are slower at 300mms.

Heck, curious if this will be like my old Titan extruder! I used a 5mm bore, 9mm O,.D. bearing. It's too large by about 1mm/.5 per side. The door does not close all the way, but it is putting pressure on the filament. Need a 5mm or maybe even 3mm bore, 8mm O.D. bearing, 4mm wide. I decided to get a straight gear as I hear a lot the twirl is not good. So I hope to get another perspective with st...
Annex Cube test after rail tramming
Переглядів 479Місяць тому
Getting closer... Tramming in the rails makes machine much more quiet and less vibration. Annex cube test for baseline. Seams are not right, non smooth surface/rough/jagged/out of place filament. Some corners not as crisp as I like. The issue I keep seeing is that when I increase PA, the seams get wider and more corner bulge. Less pa and the corners look much better, but lost the edge. Seems pr...

That printer never disappoints
That second layer speed, So brutal 😍
The joy in your voice!
Impressive. How are you liking this new duct?
Best one I made to date IMO!
@@MrRocksalt Nice! I saw your benchie video for another version and you sounded over the moon :)
2504s?
Yes, They sure are powerful motors moving this much mass! But they do resonate in the 75-175mms range.
so the decoupler protect the motor from failing, may i ask if they add any benifit to print quality ? ( getting rid of fine artifacts for example ) or better y axis shaper
is that a g10/garolite sheet glued to a springsteel sheet? what kind of glue did you use if it is? how does it stick as a print surface for different material (ABS/PLA)?
PEI, smooth, sanded, sometimes some glue stick depends on what brand ABS.
Pretty cool, bed movement is often overlooked when designing a printer, I certainly did when I scaled a K3 to 300 mm bed (I can see it moving by eye without a dial indicator 🤣) Did you see something wrong on the prints with the older system? I'm also curious about the constant force spring, is it just on the back because there's more weight there?
I have had at least 3 different bed designs; Dual screw, left and right Triple screw, rigid mount Triple belt, kinematic bed mount with linear rails at 45, 45, 90. All of them were not that good, especially over 10K accel printing. Counter weight is there to support the weight needed to not allow the rear to drift down on stepper off. This also gives more acceleration and speed to move Z since the load is put to the counter weight spring.
The seam issue looks like youre requesting E Accel above what the extruder can handle. Limiting it manually in the cfg or using more pressure_advance_smooth_time could work. But ive also had something similar looking when my duct locally cooled the tip of my nozzle to much when there was no hot plastic being extracted, although i doubt its stopping long enough at these speeds for that to be the case. Btw duct looks real nice
What slicer did you use ?
Super slicer. Same with PS and Orca.
Any stl for this or just a ring shape with a duct would be fine? I don't like my voron 0's cooling performance
This one is much more complicated than a torus with holes. But you can try!
it appears that the end of the 3d printing spectrum is always croxy😂
in my opinion its a seriously underrated kinematic system
@@trumpetsrlife9692 probably because it's more expensive then corexy and cartisan
Does having the top linear rail at an angle provide any advantage?
Angle? Does not sound good, no.
What hotend and extruder are you using, sir?
Currently this is Chube with a VZhextrudort, brass bull gear and straight gears.
@@MrRocksalt thanks
I usually print ABS in a heated chamber at 55 ~ 60 C and im planning to upgrade the machine with a Hextrudort low plus Do you recommend the brass gear set or to keep the standard POM? Straight or twirl?
POM. Don't know about twirl vs yet. No issues either way.
Brass wears down quickly because it's metal on metal, unless you're going above 85C there's no reason to switch to it
I also recommend not using the second gear at all and replace it with a bearing unless you want to go really fast, improves the quality by a bit and only lowered max flow rate by just a little bit on my machine
I know absolutely nothing about 3D printing but this is really cool
I don't know, but it's interesting to follow along with what you have already discovered, so thanks for sharing.
Is that a mosquito magnum hotend?
No, it's a Chubby.
@MrRocksalt ah gotcha, I've never heard of them before. Thanks for answering, your printer is awesome! I have the crown cooler on my Voron and love it.
totally tubular man!
Is this file avaible at all would like to test my cooling on my custom design cooling ducts in my voron. Looks like awesome results for you.
Not at this time and not finished with a barrage of tests I need to perform before committing to this duct. It's a long process.
Sorry I meant the test file you're printing. Cheers
@@jamesm3268 I would be too embarrassed to do that!
8.5 minute benchy with this level of cooling is already impressive. How much faster do you want to make it?
I can get down to ~6-7 minutes with great cooling on the VaLvNaTor duct. Just comparing for now at this speed then a bit more.
What bed probe do you use?
Euclid/Klicky
Its better to see with a Highspeedcamera Google Pixel or so
Are you offering a loaner for the tests?
@@MrRocksalt Google Pixel, Samsung Galaxy, Iphone .... most Smartphones have this Feature
@@Hinghann I am satisfied with the video in what I want to see. Maybe the pixel is for your viewing pleasure???
It's awesome that a more compact duct gives such encouraging results ! It's probably lighter too, did you make input shaping comparisons ?
Damn, nice performance!
Love the reaction
I was playing around the crown duct, and found a 360 outlet at the bottom performed a little better than just 6 outlets, but that was using 5015. The cpap style might be different.
I don't think the original crown duct can work with 5015/5020/axial. It needs some good pressure to perform. In stock form is lackluster with regard to flow. But no idea on it's effectiveness printing and at what speed. I may try a wedge design at some point, but I want to play with this duct a little. I have already added the 'valve' function of Valvnator and reduced the number of ports to 4. I need to find out how it flows 360 before I Can add more. In my mind, 4 is all that is needed + the valve slit.
@@MrRocksaltive used a similar design 360 duct with decent effect with a overvolted 5015 fan, but found the side directly opposite from the fan would still suffer when reducing the fan speed. Having a fan on both sides helped a lot. Might need to try it with 2x roborock cpap next.
Excellent results.
You got super excited on this one. Cant wait to see your improvements!
Thank you for the great video
Epic design!
that a lot of water all over everything. it still amazes me that we dont fling parts across the room with these types of cooling solutions lol
Yea, but no. You wanna cool filament or bed? 😅 Make it more horizontal, and then call it medusa dukt 🤔
100GPM needs to go someplace? We are not moving at K1/bamboozle speeds, we have to step it up a few notches.
Exactly what I've been searching for!
very nice. is it possible for you to make the bigger duct for the origina Crown Cooler duct mount aswell for those who are a bit less savvy with the CAD?
I might be able to do that, but at this stage it's not ready. Center air is not enough, so I will need to make modifications to make it like the valve duct so it can spray external as well. Will take a bit of time to design it, test it, ETC.
it would be interesting to see if directing the air in a swirl around the nozzle would have any positive or negative effect on the cooling while printing
Needitmakeit is working on that…
@MDFP with this guys ducts?
With that you loose the side cooling that you have in the valvinator… I think that in this 360 degree version you can make also external cutout to guarantee some cooling in the rest of the model
This is only the beginning. You thought I would forget the external spray.. Tisk tisk. :)
Nice!
Epic build! 🎉
Wow that’s amazing! New favorite!
The humble beginning of an incredible machine
I just dunked my HGX into the trash bin because non of the 3 gears on it are concentric enough. Bearings also wear out fast. No more ugga booga 20mm3/s TPU for me :(
How do you wire that up so it can be controlled in klipper? I just picked one of these fans for a printer build.
Do you do anything with PLA? ABS makes sense at speed, but when there's a need for PLA? I'm looking to your videos for tuning guidance 😅 so impressive
With PLA it depends on min layer time and cooling. Can print same speeds with PLA depending on layer time. Larger model=faster print/speed/accel. So think of it as a ratio between filaments.If ABS is 1, then PLA may be .7.
@@MrRocksalt that's a nice way of looking at it, thanks!
Thanks for clearly explaining your methodology in the description. Many thanks
What are you using to set the valve depth? Springs?
Valves control the nozzle orifice air. Too open and won't cool right from the nozzle. Typically I set them with about 1mm gap. Don't need much. If you are suffering on overhangs, then open a little more. More is not better.. they are sheet coolers and also hit low on the part/lower than the nozzle orifices.
I am currently building a cross gantry myself taking much inspiration from your build. Do you use 2 limit switches per axis or just one?
You must use 4! 2 per axis.
@@MrRocksalt I have been using 2 and have been having problems hopefully this changes the game for me thank you much!
@@MrRocksalt would you mind dropping the x y config for reference?
@@cristianboivin5832 Just add an endstop_pin:xx.x to each axis.
what type of bed are you using is it heated what material?
MIC-6, 10mm, 1000W AC bed heater, smooth PEI, sanded down/prepped.
takes 12 beers to put it back together
That had my dying lmao
