    The E3D is a little longer than the Robo hotend. The E3D also comes with a 3950 thermistor which is very close to the Robo thermistor. I posted https://www.thingiverse.com/thing:3180056 a shroud that takes into account the E3D increased length. The posting also includes a new hex file to be uploaded that has the 3950 thermistor table and decreases the z axis length to accommodate the E3D. Also included is the original hex so that you can go back. Just change the connectors and you are in business.

    Thank you. My hotend is giving me issues and I very well might get rid of the hex and go with the E3. Are there any specific E3D hot ends I need to look at, or is there only one for the 1.75 filament size ?

    Should just be the actual E3D v6 hotened I would imagine. @Lance Weston can be more specific.

    I purchase hotends from eBay. The R2 uses 1.75 filament. You are looking for short, Wade hotends. They come in 24v or 12v and it depends on whether I am looking for fans or heaters which one I buy. You have to patch the connectors from your old hotend or order the connectors and a crimping tool. The nozzles below are what I use. They are just the right length to go through the hole in the metal plate. I like to make the metal plate out of old tin cans.

    I just set up my R2 with the E3D with a glass plate. I used a grinder to take down the plastic in the bed in 4 places as the plastic does not add mechanical support. I also had to make a different shroud to clear the clamps. A 9 3/16 to 9 1/4 square plate is a good size.
