Delta Smart Effector + Diamond Water Cooled Hotend
-
I'm still in the planning/purchasing stage of my machine but jumped the gun earlier this year and bought a Diamond Full Color water cooled hotend. I like the idea of using the hotend as the z probe so the duet smart effector looks to be a good option. The watercooled diamond has a hole in the top of the heatsink barrel that could be threaded to accept a bolt (of course the bolt would need a hole in it as well to run wires, which isn't a big deal). I was thinking of attaching the hotend to the effector by bolting it under the effector, making sure to use spacers to center it etc.
Now my concerns:-
With the hotend being so much lower than where the arms connect I think there could be some control issues (I don't honestly know). Thoughts?
-
Since all this weight would be hanging off the effector, it seems this would affect the strain sensor to the point it would always have a false positive (I don't know if you can zero the reading).
-
Other concerns are with distance between effector and the filament input, I don't want there to be too much strain on the filament going into the hotend.
If anyone has any recommendations, additional concerns, or input, I'm all ears (eyes).

It will not cause a problem in and of itself. It will 'amplify' or 'magnify' any effector tilt. This will depend on your rod ends, rod stiffness, rod alignment, carriages, etc.

It self zeros. Not a problem.

Not sure what this question means.

@Danal I appreciate the information, thank you! That last question is kind of hard to explain, especially without pictures. The hotend accepts 5 bowden style connections, since these connections are under the effector I need to make sure that the distance from the connectors to the underside of the effector is far enough that I can physically connect the bowden tubes and keep the filament from binding due to an extreme bend radius. I also hope that there is enough room to install at least two Zesty Nimbles. I spoke to Duet, I'll be doing a mock up to see if it will work and report my findings here. Thanks again!

Well, it seems my package has been sitting at a neighbors house for about a month without me knowing, I just got it yesterday and did a quick check to see how it will look. As of right now I have no concerns with using bowden tubes with the Smart Effector. I'll be printing off a mock up Zesty Nimble to see if it will fit as well. The distance from the effector to the bowden connector is ~35mm. My only concern is with how close the water cooling attachment is to the effector (~10mm), that will be a tight fit, though I don't think it will be an issue, I may have to trim the fitting. I'll be working on this more this week and weekend and will update my findings here.

@invalidusername So I did some additional test fitting, I didn't take any photos, but it looks as though I could theoretically fit two zesty nimbles on this with the smart effector. That's the extent of what I plan to do with it. I have given it some thought and after a decent amount of research I have decided to scrap the diamond hotend idea, I'll put it on my already slow going cartesian printer. I plan to build my delta printer up using the mosquito hotend and zesty nimble on the smart effector. Once I get it dialed in I will purchase a Mosaic Pallette. For the price and headache of getting everything to work on the diamond hotend (the way I want it to) I'll be just a little over $100USD shy of being able to get a Pallette 2. At least I'll be able to use the printer while I figure the Pallette out.

I am looking with interest to your way of mounting the water cooled heatsink to the smarteffector. Do you have something planned for that already?

@invalidusername As a long time user of Diamond hot ends, I'd say that you've made the right decision. I know very little about Deltas, and I have seen Diamond hot ends mounted to them (albeit not water cooled) but these are still seriously heavy beasts and 5 Bowden tubes or flex shafts trying to pull an effector in all directions would be a concern I would have thought (but I know very little about Deltas so might be wrong).
