Constant problems with SmartEffector
-
Where to begin...
6 pin molex is a poor choice, I've had to replace 3 already, chasing down bad crimps.
I had to sand the mounting hole for the heatsink a little just to get it to sit flush with the pcb. I can only get it to seat if I tighten the nut. Wonder if this causes any strain on the sensor.
Had the effector working briefly, after finding that just hanging a print cooling fan was enough to activate the strain gauge. After adjusting the sensitivity a little higher the turn off the led, now it's saying it's triggered before probing a point, but the led is not on.
I've had the sensitivity adjusted a few times and, well.. this just seems like too much hassle to get something working that should work out of the box.
Very frustrated by this product.

Sorry to hear about your frustrations.
I assume you've followed this guide? https://duet3d.dozuki.com/Wiki/Smart_effector_and_carriage_adapters_for_delta_printer?revisionid=HEAD#main
What is your current configuration for it?
Can you post a photo of the effector?

So far, it's been all my issues.. I found that the z probe out had somehow broken at the connector after working fine. I went ahead and soldered all the end connectors and wire ends before reassembling.
Still not a fan of the molex 6 pin.. I've just soldered on the connectors and isolated with heatshrink. I figure out how to keep it secured later, although it's working just fine as it is.
I have followed the guide. I've built a Kossel XL from components off RobotDigg. I'm using a Duet2 wifi (which had been previously used on a Rostock Max and an open source cartesian). Normally I've used a BL Touch for z probe and haven't had any issues with it.
Still working through the cooling fan issue. I've run a first print and it looks great. Far less frustrated now.
I'm going to attempt to install the cooling fan again. I've found a few different designs that mount across the arm width, that hopefully won't add any strain to the effector.
Thank you for your patience and understanding.

Well that's good.
The effector still seems sensitive to have the weight of a fan trigger it off. Though fan running has been known to trigger erroneously as well.
Can you also provide a side view of the assembly?

@seanc68 are you aware about swapping polarity on the arms?
If those are Haydn's magball arms, all the stickered ends have the opposite polarity to the none stickered ends.
Aim to arrange your arms so one has the stick at the carriage, the next at the effector and so on. -
@jay_s_uk I was not aware of that. I mentioned that to a friend who also has the same setup and he wasn't aware either. Thank you!

If you don´t swap polarity You can have some fan issues, like not spanning t all

I have a 111gram extruder assembly on top of my smart effector, a typical E3D heatsink/hotend/fan hanging from it, and a 5015 part cooling blower fan with duct also hanging from it. The only problems I have with it falsely triggering are the result of my crappy linear rails vibrating.
