E3D Hermes

Check out Tom's video at https://www.youtube.com/watch?v=W6U-u0wBdfQ to see what we have done with the Hermes and Duet 3.

I really like my Delta, will it be compatible with the Smart Effector?

i think it would be to heavy for a delta. the whole point of a delta is to keep the printhead light.
-
It's too heavy for my delta. AFAIR, in the interview Sanjay gave the weight as 480g. He also said that they had gone for a more powerful motor than needed, to cater for electronics where setting accurate motor currents was difficult. That's a shame for those using Duet electronics.
-
The next best thing would be a Smart Effector with can bus. I believe there was a post about a new smart effector in the works?

I'm not sure it'd be too heavy for all delta's. There are a few direct drive deltas that use titan aero's already (or, in my case, a titan + v6 with a piezo orion shoved in between.) If this new "hermes" is within a few grams of a titan aero with standard e3d motor, the swap might be feasible.
What I'd be more interested in knowing is if Duet is using their close relationship with E3D to have some kind of strain or piezo sensor built in or on for auto-leveling.
Imagine the appeal of a single compact "unit" that has a dual geared extruder, motor, hot-end, and auto-leveling gauge all in one without having to kludge on extra parts. Yet, still using standard E3D nozzles... Oh, and the entire thing drivable with only 6 wires if using a tool board?!

399 titant aero with motor vs 480. to thats 20% more.

E3D Hermes is great and coupling with Duet 3 also. But I want to inform if one doesn't know that Dyze has announced interesting hotends at this TCT also with more flow than SuperVolcano - to let you know alternatives. Interesting times with interesting innovations! https://3dprint.com/254892/dyze-design-new-extruders-typhoon-and-pulsar/

I'm not a fan of the whole assembly, but I like the new heatbreak and the shorter filament path.

Hermès weighs 366g, not 480g.
It does have a ridiculously oversized stepper that weighs about 260g itself. For comparison a bmg, also with 3:1 gearing with a 140g 20mm pancake works perfectly for me on my d300vs delta.

@JoergS5 bugger, missed their stand. i was looking for other hotend providers!

I don't think that's a fair comparison. The "Hermes" is supposed to be a stepper motor, extruder, and hot end assembly all in one. What is the weight of the BMG/motor combined with a hot end assembly?
-
@garyd9 It ends up being about the same for a bmg+stepper+V6. 330g iirc. The point is Hermes could be 120g less and still work.
-
IIRC Sanjay sad they are looking to put in lighter motors in later iterations.

Cela devrait bientôt être annoncé à grande échelle
Now available for sale, but under another name (perhaps a problem with the Hermès Paris brand). I look forward the comments on how it works.

and just in time the first upgrade guide from tom

@Rudy2A it was a certain delivery company that threatened legal action the day before they were due to launch
Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

@jay_s_uk said in E3D Hermes:
c'est une société de livraison qui a menacé d'intenter une action en justice la veille de son lancement
The day before its launch ... So that means that there is a series engraved "Hermes" no?
-
This new thing looks great, but it looks like the heat break just screws into the heatsink, the same as the V6. Did they do anything to secure it in the heatsink?
I've had the heat break come loose from the V6 hot-end many times during prints, screwing up the print quality. There is no way to securely mount the heatbreak in the heatsink- there's nothing to grab with a wrench on either the heatsink or the heatbreak, and no set screws. You can't twist it in by grabbing the heater block because the throat of the heat break is so thin it will break.
