Is there a compatible Hot End that works with the R2?

    Tried one before, but it was too big for the plastic enclosure. Any tips on an R2 compatible replacment? Mine is leaking plastic out of the top. Also, if I want to replace the nozzel, what size is it?

    thanks

    The nozzle is a standard E3D compatible one, stock is 0.4mm nozzle size. You can get them from anywhere - look on Amazon for start: https://smile.amazon.com/Nozzles-ExcelFu-Extruder-Filament-Printer/dp/B07JFGXC5N

    I prefer the hardened steel ones myself, but brass is fine if you replace them periodically

    The R2 uses a Hexagon : https://www.partsbuilt.com/r2-hotend-assembly-robo/

    If you want to swap to something else (like an E3D) you need to remake or modify the carriage -- there is a thread on this already here.

    Look on thingiverse.com. Search robo R2. I designed a new shroud that allows you to use an E3D clone hotend. I buy the hotends for about $8 on Ebay. You have to put on the Robo connectors.
