  • I previously tested the E3D Revo hot end system on a high speed SecKit SK-Tank coreXY 3D printer, and was pleasantly surprised by the performance. The system offers convenient, tool-less swapping of nozzles, so it works best in my opinion when multiple printers have the system and can share components. In this video, I fit a Bigtreetech H2 V2S Revo to my Ender 3, a Revo Micro to a Prusa Mini, and test the new abrasion resistant ObXidian nozzles from E3D.

    I have been tinkering with my E3V2 again after not touching it for a while, and decided to finally make the switch to DD. Came across this vid while researching some extruders, and I'm glad I did, because I've been struggling with what direction to go, and whether to change my hotend as well, and now I've decided to jump in with both feet and order up the H2 Revo. Seems like it ticks all the boxes for what I want!
    I really appreciate the way you conduct all of your reviews and vids. Tons of info, and transparency. You just saved me from going down a rabbit hole of spending too much on multiple different setups to tinker with to try and find the right one.

    My Revo just arrived today and I'm super excited to get an ObXidian nozzle. Leaks and buildup on my current nozzles are what motivated me to go with Revo. If the ObXidian works like brass and picks up even less filament, then I'll be in heaven.

    I've been using the Revo for months to print a lot of stuff, including a bunch of Gridfinity boxes, and it's been completely drama free. Been swapping between sizes, and just pre-ordered ObXidian as well so I can run abrasives and anything else I want through. It's a great system that makes nozzle changes sane. Having to muck around with tools and with the nozzle at temp is stone age stuff, and this also eliminates the possibility of leaks at the heat break. Currently just running on a MK3, but any printer I get in the future needs to be Revo compatible.

    Been running a Revo on my Mk3S+ for a few moths now and i love it, i went from never changing nozzles to switching out all the the time now depending on what i am printing. Been waiting on the new ObXidian nozzles so i can try printing with some new filaments, as it is so quick i can see me still using my brass ones for everyday pla prints and then switching them out when i print with anything abrasive.

  • @nightlurker
    @nightlurker ปีที่แล้ว +11

    I have used the Revo on a Mk3S for the last week, approx 150 hours of print time, and I am extremely happy with it so far. I have just pre-ordered the ObXidian nozzle, as like Michael I also want to fit and forget my nozzle regardless of the filament I am using. After replacing my V6 nozzles about every 6 weeks or so (my printer is almost constantly on the go), hopefully these will last a bit longer than the nozzle X from E3D.

  • @therealharleybutler

      keep in mind that if you're ordering from a reseller that they would have ordered that stock from e3d far in advance, so even though you wait for a first batch of direct e3d orders to happen you might be purchasing an nozzle from the exact same production batch from the local reseller

    I've had a Hemera XS Revo for a few weeks now. I love it so far, about to pre-order the Obxidian as well. I've been getting into glow filaments (Sainsmart PETG & TPU), and while they print quite well quality wise, I can feel the grit on the filament and feel confident it's going to destroy the brass rather rapidly.

    I have the h2 Revo and love it. Results have been on par or better then my ddx v3 I had on the machine before. While more money, I like the easy of taking out the nozzle for clogs which I did cause from my z being too low. Obsidian nozzle is not on my radar at this time, however as I can leave it in for pla or abrasive materials I may look into it.

    I've been through a few editions of the revo beta nozzles and until yesterday was sticking with the original beta which was just the heater core as I was using a standard hardened steel nozzle to print Prusament CF PC. Decided to switch over to the final beta (basically the revo micro with two nozzles without the coloured rings) in preparation for the Obsidian coming whenever they sort out their production issues and just run it on regular Prusament PC and standard filaments in the meantime.

  • @Twxii

    I switched to a Revo Voron just last week on my Voron V0.1, I previously had a Phaetus Dragon and when changing nozzles it would twist the whole hotend slightly and touch the hotend fan. The Revo Voron form factor makes a lot of sense on a small machine. Only have a 0.4mm nozzle currently but will be looking to get at least a 0.25 and 0.6. The Dragon in my 2.4 is still easy enough to change nozzles.

    I've been mostly happy with the revo but flow has been the limiting factor. I'm glad they finally have abrasives covered, but I would love to have a revo volcano option. I would happily buy a new heater and nozzles if high flow was an option, because I love the integrated heatbreak and toolless nozzle changes.
    The revo as is is also a tough sell financially when similar hotends like the Rapido can get more flow with more nozzle options and still have one handed (but not toolless) nozzle changes.

  • @deandavies1462
    @deandavies1462 ปีที่แล้ว

    I converted my anycubic Vyper first to E3D V6 volcano with a hardened steel nozzle which was a great swap for the original fake PTFE lined volcano hotend that came on the machine. With a redesign of the hotend assembely to accomedate the longer legnth of the new V6 volcano mounting to the machines strain guage. I then made the jump to the REVO 6 about a month ago and im very happy with the swap, even though it ended up as another redesign of the hotend mounting assembely to work with the anycubic Vyper strain guage mounting system. This really hinders hotend choice as mounting requires 2 vertical mounting screws through the top of the strain guage into the hotend which is not ideal with the REVO V6 but was solved within our vyper facebook community. The only problem I had was not being able to swap out to use hardened nozzles to print abrasive fillaments, I missed the ability to use all my fillamens, bur now have ordered the 0.4 & 0.6 obXidian nozzles. Now its sitting and waiting for the mid november deilvery date to roll round.

    I like the Revo system so far, but it wasn't the smoothest upgrade. First, the latest Prusa Mk3 firmware 3.12.2 doesn't work with the Revo. It fails during the PID calibration. This is a known issue, but it took digging through Prusa forums to figure out why PID cal kept failing. I ended up doing a complete xyz re-cal on my Mk3S after upgrading to the Revo as well. I didn't realize that was going to wipe all my existing z offsets for my different plates, so I had a really challenging time getting everything dialed back in. I read on the Prusa website that the first layer calibration routine does not work with the Revo. I can confirm I had terrible results, every first layer calibration look very under extruded, so I thought it was interesting to see you had good luck with it on your mini.

      It does not. Per Prusa: Due to the support of custom extruders, we received requests from the community to enable Marlin PID in the firmware. We have performed multiple tests using different materials to verify the “Prusa” thermal regulation works correctly on both stock and custom extruders. The results below show clearly that the current algorithm (a feed-forward driving + PID tuning of the steady state) is capable of correct thermal regulation in all tested scenarios including the sudden start of a cooling fan.

    I wanted to print a small text stamp, using a 0.2mm nozzle.
    So I purchased a nozzle set from Amazon, that are exactly the same size & length as the stock nozzle that came with my Ender 5.
    When I put it in, the Amazon nozzle hung lower on my Heatblock. The stock Creality nozzle seems to have no threads near the heaterblock end, and must somehow nessle into the heatbreak; because it fits in deeper..
    Resetting the BL Touch to allow for that was not a problem, but I worried about not having the 'hand in glove' fit to the Heatbreak that the original Creality part must have.
    My Amazon 'butt faced nozzle' started leaking only after a few prints; and I know I tightened it properly. I need a source for a 0.2mm nozzle.
    Where can I find tappered nozzles that have the best fit to the Ender products? I was considering upgrading to a 'Slicer' heatbreak, but pictures seen to show that it too has a tappered input end for nozzles to interface; so flat faced Amazon nozzles must not fit the best.
    I'd love to hear your opinion on this concern.

  • @axelSixtySix
    @axelSixtySix ปีที่แล้ว

    Well, as an old reprapper, I'm not amazed by the Revo system fore some reasons. First, Nozzles are wearing parts and expensive nozzles are not a good idea. There's not much perks to switch nozzles that often. Generally, every printer have its matching nozzle : 0.4 for general purpose, 0.6mm for production and, like on your Mini, 0.2mm nozzle for high detail FDM prints. Even if you own a single printer, I'm not sure you'll swich nozzles frequently. Maybe the first weeks to play or test differencies, but after a while, you'll stick to a fixed diameter, and forget it. IMHO the average guy will change a nozzle only when it get old, so maybe a couple of times per year, and the old style procedure with tools is no big deal, as it takes less than a minute. On the other hand, more than 20€ per nozzle is unnecessarily expensive. I noticed the hardened nozzles do not last much longer as there's several reasons for replacement : nozzle shape (abrasion, and mostly deformation because of the heat/cooling cycles) and charred filament residue. As a print farm tender with a lot of nozzles change, it's a no go, despite the piece of time saved. Another inconvenient truth is the all in one heat core: there's some frequent complains online about failing heatblocks, thermistor or heater. Once again, you have to change the whole expensive thing spending much time than for a single thermistor or cartridge. Last but not least, the V6/Hemera already printed perfect and did not leak, so...
    IMHO, the Revo is disavantaged by its overall maintenance cost and the claimed perks are questionnable. The Micro is the real improvement, except the Revo system. A micro V6 would put my money out of my pocket, but not the Revo thing. I will keep on buying V6 or so.
