@@draildrums Turning up the speed on the display keeps the acceleration and extrusion rate limits. In the settings that@@fail_fastgave us those values are raised from the default.
@@Dann.y Ah ok, yea just was wondering I don't really mess with speeds and always wondered if just turning the knob would suffice for a little bump, say if I was going from 100 to 150
In your triad, I would replace melt with "extrusion system". Even with plenty melt capability, without the filament grip and extrusion force to overcome backpressure, you won't get high flow.
But this mod changes the weight and CG of the toolhead, without the accelerometer on the toolhead wouldn’t it be a problem?. Not having it on a printer this expensive is a massive oversight from Prusa
Love it: - that's how you beat any other "speed-heavy" printers out there!! :D On that note, I wouldn't overdo it with PETG : ) Nice. Don't you think that Prusa knows the "secrets" of higher flow though? Unfortunately not all of the projects are "open". It would be much easier for everyone - including Prusa - if more manufacturers cared more about open source like Prusa does. In fact, the Prusa nozzle technically is not proprietary.
why didn't you test the CHT nozzle on the nextruder? If the V6 results are anything to go by, it would be VERY close to the volcano results, without needing the larger heater block. More powerful heater might still be needed, though.
The CHT was the first thing that I tried even though I didn't mention it in the video. The heater was underpowered and couldn't feed the CHT nozzle. One of the main reasons I went for a volcano is because mk4 uses a custom length heater cartridge and 50w heaters aren't available in that size (or they weren't 6 months ago)
Great video! I might give this a try. I think the MK3.5 is also a very interesting candidate for high speed printing, as you can easily install any hotend, such as Revo HF with 50W heatercore, Phaetus Rapido or Goliath.
Could you please describe the settings you made in prusa slicer? Did you just change the max volumetric speed? I also think you forgot the thermistor in your list. :) Do you use a 0.4mm Nozzle?
you can use the same thermistor! Basically all you need to do is bump up the flow rate, you can start with increasing it by 50% but I've been able to push it up to 100% when I want a part done RIGHT. NOW. You'll want to increasing your part cooling fan as well. After this, you can basically increase your speeds and accelerations to whatever you want. I've pushed it up to 500mm/s and 15k but I haven't run it for hours on end. yep, 0.4mm
CHT nozzle can easily get 35mm3/s without a noticeable drop in quality/adhesion with just the V6 adapter (from my own flow tests - I use orcaslicer's flow test to determine this), so I'm not sure why yours is so low.
Different filament brands/colors, different testing methods, and different environmental factors all can add up to that. For instance, I use CNC Kitchen's method and occasionally use orcaslicer's flow test and get different results. Not a big fan of orcaslicer's method, even if it's faster, as it's harder to quantify scientifically compared to weighing blobs. Still, clearly practical as it's popular.
@@applepiesapricots3109 Orcaslicer's method I prefer because its far more rooted in how it actually looks in a real printing situation, and you can also determine part strength etc. too.
Also to add - put x/y jerk to 30 and watch it go brrrr That and CHT nozzle = it's now actually a little faster than my P1S and print quality is still exactly the same lol - maybe I'll tweak the P1S next as I have the Obxidian CHT nozzle in it
@@fail_fast Did you ever upload a video of a car accident? I might be going nuts but I thought I saw something like that on your channel before you disappeared
Have followed all your instructions and purchased the specified parts. My Mk4 consistently fails the loadcell calibration tests with the E3D adapter and included .4 brass nozzle, Reinsert the stock parts and all works well. Any suggestions - have used multiple E3D nozzles with the same failure.
Firstly, that's a low blow at IS. MK4 has had IS for so long now that some people wouldn't even know if didn't exist. Secondly did you have to modify the firmware to enable this hotend? Did it mess up the thermal profile prusa set in FW for runaway? I also wonder how this mod affects IS as your adding a fair chuck of weight.
No FW changes needed. I've been running this mod since IS was released - it just took me forever to make the video 😅. No issues with the stock thermal profiles. It only adds a couple grams of mass to the entire 500 gram nextruder assembly so IS is unchanged.
This is interesting, but if it won't produce equal part strength and print quality to going normal speed it isn't of much value to me. We want the best quality these machines can make. Even input shaping speeds often reduce overall quality compared to going a bit slower.
Thank you for posting this. I'm pretty new to printing, just started with a Sovol SV07+, and it took me awhile to figure out that in stock form it has substandard parts cooling. The directional curtain fan on the back of the X crossbar is part of the problem - it creates differential cooling zones across the width (X) of the plate as well as by exposure time, with the -Y areas of the plate getting the effect continuously and the +Y areas not getting enough. This leads to differential layer heights if you're running the thing at speed, then the nozzle starts knocking on them, etc. Finally worked out a design for dual 5015 blowers to ride on the print head. Seems to have solved all of the problems. Curtain fan is now removed. Also the overhangs look much much better now :) Anyway it's up on printables if anyone else has a SV07+ with the same problem.
Not that it would concern me, but wouldn't it be more practical to have the Nextruder Adapter act as the Volcano Part ( longer thread portion ) thus enabling the use of _actual_ nonproprietary Nozzles instead of like this requiring _somewhat_ proprietary Volcano Nozzles? 🤔🤨
I get what you mean! I use a nozzle spacer to accomplish this (see the link in video description) it allows me to use standard length V6 nozzles with the volcano block
You can have a ton of motor torque, it's easy. What's not so easy is transferring all that force onto the filament without it slipping back. That being said the MK4 with its giant extrusion gear and two idlers should have the least issue doing just that?
Part of the "ghosting" comes from the fact most slicers do a super crap job of using arcs. Running through arc welder can drastically what appears to be ghosting on curved walls.
I have always thought the cooling on my mk3 was not good enough. Has that changed on the mk4? Clearly it is going to be more important with your volcano mod. I would love to see a video comparing stock cooling vs upgraded.
That would be the matter of material choice wouldn't it? PLA has a really low Tg so it takes a fair bit of effort to get it to solidify; PETG though and especially Styrene polymers (ABS, ASA, HIPS) don't need much effort at all. I have a DIY printer not a Prusa and i have a Sunon maglev 5015 part cooling fan... it was a mistake, the maglev bearing really hates vibration so i converted it afterwards, and it has another issue with PWM control as well, it just goes crazy, which i had to work around with a DIY pi filter, but the fan does differ from ones usually supplied for 3D printing by being a fair bit more powerful. I can get a lot of air in. But i heard the commonly sold used Delta 5015 fan rips even harder. I should try it. DBB is the right bearing type for machine. By the way i can really recommend HIPS. Matte, little shrinkage and warpage, open printable, good cohesion, cheap, high temperature capable, very smooth and controllable flow, lightweight, less degradation in the nozzle than ABS, less styrene vapour emission by an order of magnitude. Still poisonous though.
Very interesting comparison. How about a Nextruder with CHT Nozzle? If normal Nextruder is better then V6+CHT how about Tuning the Nextruder-Block with the CHT Nozzle?
I should have mentioned it in the video. I tested a CHT first but the heater didn't have enough power. The nextruder uses a custom sized heater and they aren't available in higher wattages. The real reason for moving up to the volcano was that we could use standard length cartridges heaters which are available up to 70w
@@fail_fast interesting that the heater of the nextruder is not sufficient for the cht nozzle. I am using a cht in my mk3s+ and have no problem going up to 25 mm³/s. I was hoping that the nextruder can bring it at least to 30mm³/s. I mean, in the end most of the filaments that I use aren't made to be printed that fast so it is not necessary for me, but it is always good to know your system, right?
There is a quite good reason why to set lower limit for PET even when the nozzle can melt more (see Prusa and Bambu printers for example). So comparing 9.5 vs 20 may not make much sense.
Why actually? I mean i have noticed that PETG "likes" being printed at consistent speeds, with not too much retraction and non-print moves and not too much acceleration deceleration in the extrusion, and the higher you set your speed, the more real speed variance you're going to get, but i don't understand why this filament behaves the way it appears to, what the underlying cause is.
