Duet3D PCB delta printer effector sneak preview
-
The carriage adapters are just pieces of PCB, so they cost very little and it wouldn't make sense to offer the effector without them. They are designed to fit existing carriages with M3 fixing centres on a 20mm square. As for dimensions not matching, you are always going to have that issue if you want to retrofit a commercially-made effector to an existing design without fitting new rods as well.
If you already have an E3Dv6 then you shouldn't need a complete new hot end, just the new heatsink.
-
Aren't there advantages to having the nozzle as close to the effector plate as possible?
I've seen folks use standoffs on the effector plate to get the mount for the hot end assembly up higher.
Not a good idea?

Mounting the hot end higher gives you a little extra build height. Also if you don't manage to eliminate effector tilt then it may reduce the resulting print distortion.
We considered whether we could mount the bottom of the heatsink to the effector instead of the top, but we couldn't find a practical arrangement.
The PCBs for the next version of the effector have arrived. This version has the top of the heatsink going through the effector, so the distance from the nozzle to the effector is reduced somewhat.

Could you share a drawing of the top of the heatsink and mounting to the effector I need to get Lykle on board to design an adaptor so that a Nimble extruder can be mounted to it?

Hey guys!
Any updates on this?
I'm just waiting to order

Quite interested in this as well. Wound up machining a similar setup out of AL but without the electronics. Works rather nicely with the rod ends absolutely parallel.
-
I've published the preliminary fitting instructions at https://duet3d.com/wiki/Smart_effector_and_carriage_adapters_for_delta_printer. I also added some photos, including this one:
This is our second prototype. The electronics is working even better than in the first prototype and we have been able to increase the sensitivity, so that the probing force is lower.
The combination of magnetic joints and two connectors (one for signal connections and the other for power connections) makes it very easy to remove the effector - the hardest part is removing the Bowden tube and filament from the hot end.
The main thing we need now is for E3D to finalise their new heatsink design. We may also make the effector a little larger to make the underside less cramped, which would increase the rod separation from the current 55mm to 60 or 65mm. Do any potential users have strong views on this?
-
I machined mine at 55 and about the only thing I noted is having to be a bit more careful about anything mounted to the vertical tower and staying clear of the mounts (how. Do I know this,..it wasn't pretty). Larger seems like a good notion though.
Think a larger size would be useful if this got extended to two hot ends in the future.
-
Im in for a full set as soon as they become available.
Thinking out loud on the wider spacing : would there be any noticeable deflection with the wider rod separation ?
And personally I would be modifying my Prometheus hotend to fit the effector, therefore could i ask for a picture of the modified e3d hotend out of the effector to see whats going on.

Just wanted to stop in and say this is looking fabulous. I've been looking for a solution to house multiple tool heads with quick disconnects and this looks perfect for that.
A couple of features I'd really like to see:
1. A single connector on the back that can be universal for all the different tool heads (hot end, laser, cnc, touch probe, etc)
2. That single connector is a magnet style both for safety and for a quick change.
3. I'd like for the rods to carry current either for the connections needed (there are 6 connectors) or for fault-tolerant break detection.
4. a purple color from osh?Again really good work and thanks for sharing. If there's a beta or early product tester program sign me up.

i vote for magnetic quick change too. as for connector - if i change tool, how than board will differentiate which tool is connected?
if it does then firmware may automatically adapt for the tool. -
The PCB effector uses two connectors, one for signal wires and one for power wires. This is to reduce the risk of mis-wiring causing a short. A magnetic connector might work for the signal wires, but I doubt that it could be used for the power wires.

Have you seen the repair percentage on apple products power circuit ? a prime example of what NOT to do…......

So the big question is when to expect availability on this seemingly very cool and precise product development?

Once you make a defined scheduled, circumstances beyond your control will always delay it three to six months!

Haha good ol' Murphy hard at work…

I'm also very interested in this as I may need to replace the somewhat bulky aluminum effector on my TEVO delta in order to fit a DyzEnd-X hotend. In the meantime I'm going for a hacky solution.
-
Last week we agreed the new heatsink design with E3D. So production will start soon.

Pre order any time soon?
