Hydra Adapter for Replicator 2/ Clones (X-Smart) (With Optional Belt Tensioner)

thingiverse

Just because you can doesn't mean that you should... Finally an updated carriage for the X-Smart! This design includes a front and back adapter for the Hydra Tool Change System: https://www.thingiverse.com/thing:4062242 or the V6 edition: https://www.thingiverse.com/thing:4253359 You will need to print the Ender 3 parts for your desired setup from the Hydra link. Installation is pretty simple, just print the carriage back and then follow the hydra installation guide for whichever hotend you choose, up until the duct installation (don't put those on yet). Instead of installing the M8 spacers, use an m3x12 (or longer) and an m3 T-nut (see images). You can either start with the setup installed on the rails, or you can wait until this point and then attach it. Next, attach the carriage front. Using m3x20 screws, secure the front to the rest using the duct mounting holes, but don't screw in all the way. Attach the ducts, and then tighten the screws. The ducts should only go in at one position, and it should be a relatively tight fit. Any of the extruder options from the hydra will work (I'm using DD). There are options for a back with built in tensioners or a front with a BL Touch mount to attach (using the BL Touch mount in the hydra files). Obviously, this will require either an ender 3 / 5 hotend (available for like $5) or a v6 hotend. I haven't tested compatibility with all v6's, but in theory any that fit the Hydra v6 mount should fit here. Also for my X-Smart users, this was built with cables running all the way to the motherboard, and not the stock ribbon cable. I'll post a tutorial detailing that project soon. You will also need to remove the cover on the back of the enclosure (overtop the z-axis) as the extruder is much closer to the bed and the bed will collide with it. On the same note, I have only tested with the X-Smart, not an actual Replicator or other clone. This is the same length as the stock carriage, so it should fit, you might have to move the endstop though (I had to hot glue mine lower so that it would hit). I have used both the standard and v6 versions, pictured are the v6. For safety (I didn't like the way the cables hit) I did reduce the total build size of my X-Smart in Cura. Depending on how you run your cabling, you may not have to do this. Print all pieces in the given orientation, I used 0.2 layer height, 40% infill. Supports necessary. For the carriage parts, I recommend a brim or raft.
