Body 49

This is a revision of the former, now defunct, Body 54. 

Body 54 had some issues: I didn't really understand the movement of the arms on SR and V400 effector plates. While it would have been possible to place the Revo Roto on the SR plate, the nozzle would have needed to be off center in order to accommodate the arm movements. It felt like an invitation to, if not disaster, at least difficulties. 

Body 49 has been entirely reworked. It is modeled solely for the V400 plate. If you have an SR, you can purchase a V400 plate and it will work on the SR, with the loss of a small amount of build volume. Body 49 also abandons the piezo probe. The small wires proved too fragile to easily manage on the toolhead. 

To build, 

1. print with copious supports in ASA or the like, using standard Voron parts settings, or whatever you feel like. 
2. Clean as necessary and place M3x4 heatserts for the lower ebb holes. 
3. The Roto should go inside Body 49 and then be securely screwed to the effector plate. If you have the “censored” version, you should probably insert and route the cable before you insert the Roto into Body 49. 
4. You'll need a longer screw for the back left hole, and it looked tight in my print and may need to be ever-so-delicately reamed with a drill before installation. There's a through hole under the ebb for cable routing.

Nothing is Ever Easy…

Oh, and you'll need to remove a touch of the plate from the underside to make room for the heat core. In an ideal world, the area should be milled—the Roto doesn't have a flat bottom and it's not sitting on much, so it's a balancing game between making room, maintaining structure, and providing an air gap to reduce heat transfer...

Fans

The V400 plate is made for 4510… But…. I didn't have any and, more so, I couldn't readily locate a model of one. Use 4010 blowers, with a couple of small screws to secure them in place. 

The Roto heatsink fan should provide some airflow over the Ebb as it exits. I finally actually printed this tonight so I'll assemble it this week and make sure that's the case.

2/12/2024 The test print assembled better than expected. I did do a little filing, but the blower  fans fitted very well into their slots. When tightening the model down, it cracked on one side (marked in the photos). I'd like to blame the supports, but from what I could tell the top seemed to fit as intended, so…. I probably need to reduce my flow a little, but I like having a lot of material so the print is really full… I was afraid the model was going to be too tall and the Roto would flop around inside it, but the opposite was the case. Will rework a little more this week and adjust the right blower carrier so there's room for the 24v fan cables. Also didn't size the two lower ebb holes correctly for heatserts…
