    Didnt see any posts about it but was wondering if anyone has tried either of the mosquito hotends on a robo r2? Not looking to upgrade soon but wanted to know if it was a plug and play replacement or a more destructive replacement. The Mosquito and Copperhead both look to be shorter than a hexagon ( not entirely sure because im getting different measurements on the total length of the hexagon from each seller compared to my own hexagon.) Just wondering if anyone had any opinion on their use.

    I haven't, but someone may have.
    I am thinking that without building a new one the existing carriage for the hotend will not fit -- you can't use an E3D without building a new carriage. The spacing on the cold section mounts for the hotend are pretty specific to the Hexagon.

    When you say cold end mount spacing do you mean the dimensions of the collar?

    Yes, exactly. The spacing is different on the Hexagon than the E3D and it may well be different from the Mosquito as well.

    Here are some dimensions that they sent me in case anyone reading wonders. dont have access to any good calipers at the moment so i cant say how close they are to the original hot end. The top picture with a top collar dimension of 2.2 is the copperhead with the second picture being the adapter they sell for use with the mosquito hot end.

    Those numbers look very close (as in "identical") to the E3D : https://e3d-online.dozuki.com/Document/Ztd4NlQ3MF2x61nj/V6-175-SINK.pdf
    So it is likely that the mosquito will have fitment issues as well. Someone did design a new carriage for the E3D to fit into the R2/C2 and you can find that information here on the forum if you are willing to replace both.

    I would say that differences in the overall length would be a major concern.

    The Slice Engineering Mosquito hotend has a very unusual shape and requires a very different method of mounting compared to the more popular E3D V6 design, which in turn is bigger than the Hexagon hotend used in stock Robo3D printers. Here's the Mosquito hotend:

    By contrast, here's the Hexagon:
    [​IMG]
    The Hexagon fits into the Robo3D's carriage via a small hole with a bracket that grips the groove near the top of the hotend. Thus, anything that lacks that groove mount, or that has a groove mount that's a different size (the E3D V6's is bigger, for instance), will require either an adapter or a replacement carriage. There's at least one carriage design on Thingiverse intended for the E3D V6, so that replacement is do-able without designing a carriage yourself, although you'll have to tear down and rebuild that part of your printer. A quick search of Thingiverse turned up no equivalent hardware for a Mosquito; however, I may have missed something, especially if it's something intended for another printer that would happen to work with a Mosquito.

    Instead of a Mosquito, there are a couple of alternatives that might interest you:
    • The Slice Engineering Copperhead hotend -- This hotend is made by the same company that makes the Mosquito, and it has some of the same technologies. It's much closer to an E3D V6 in overall size, shape, and mounting, though. In fact, it's modular and you can swap in and out E3D V6 components. I have a Copperhead on a Kossel XL Delta printer that uses a Delta Smart Effector, and I'm using the special E3D V6 Smart Effector heat sink with my Copperhead, as well as a V6 heater core and thermistor. (This is, I'm using the Copperhead heat break, heater block, and nozzle.) Thus, you could use at least part of a Copperhead in conjunction with a carriage designed for an E3D V6. I don't know if the Copperhead heat sink would fit with this, but you could always use a V6 heat sink. Note that the Hexagon and V6 heat breaks are not compatible, so you could not use the Copperhead with the existing Hexagon heat sink and Robo3D R1+ carriage.
    • The Phaetus Dragon or Trianglelab Dragon hotend -- As I understand it, Phaetus designed this hotend, and Trianglelab licenced the design. The design incorporates key features of the Mosquito into a package that's exactly the same dimensions as an E3D V6. Thus, you should be able to put either of these hotends in a carriage meant for an E3D V6. Note, however, that some of the features of the Mosquito that the Dragon copies are patent-pending, which puts these hotends into a bit of a legal and ethical gray zone.
    Either of these alternatives is likely to be easier to install than a Mosquito, since you can use a V6 carriage design. Depending on why you're interested in the Mosquito, either or both of them might provide those benefits. Unfortunately, I don't know of any drop-in replacement for the Hexagon that won't require printing a new carriage and doing some significant tear-down and re-building of the assembly. Thus, these aren't what I'd call easy upgrades. Fortunately, Hexagon hotends are still available, so if your hotend dies completely, you can replace it without too much difficulty.
