Smart effector poor sensitivity
-
Hello,
I'm trying to get an anycubic predator running on a duet 2 with smart effector v3.
Currently having the exact symptoms of this thread.
https://forum.duet3d.com/topic/26432/smart-effector-poor-sensitivityAt 10 sensitivity I can sometimes probe successfully, inside the -.40 range with G30 S-1. Around 50% of the time it will crash to -3 or more mm and lose steps.
At 8 its borderline unusable with constant triggering, 9 kind of works 80% but will still crash on occasion. Anything above 11 will always crash, and below 8 will stay triggered or just flash.
Checked wiring, and nothing out of place or intermittent.
Using included e3d heatsink, no mods.Thanks!

Is this a new smart effector that has never worked correctly?
When and where did you purchase it?

@Phaedrux
New v3 from filastruder last month. First time testing it. -

Will do ASAP, thanks! -
Sorry its been so long, holidays and the new year where busy.
But i got around to installing and testing the replacement smart effector and am seeing similar behavior going down to 13/14 sensitivity, is the only spot where it sort of works. But Its still unusable and crashing randomly at any sens. It seems to always crash a handful of times off a fresh boot and then works for a bit then starts crashing again. This action is also repeatable by just tapping the nozzle and watching the led blink, it'll work 5 in a row then stop and need a much firmer hit to blink again then work on and off for a bit. Have verified wiring, no broken wires or pins.Not sure of anything else i can do on my end.
Possible to upgrade to a v4 or something to avoid more just swapping and testing?
Thanks!New Run #s

Can you show some photos of your print head and mounting?
-
@Phaedrux
Fans are off as is hot end during probe testing, everything is tight, no parts are loose, no play in effector. Is it possible fan mounts could lead to inconsistent readings? Should I pull fan mounts and test with only the hot end?
Thanks!Current one installed
Previous pulled prior to disassembly for replacement.
-
Can you test it with your printed parts removed? I suspect that they are stiffening the effector and impacting the sensitivity of the strain gauge.
-
@Phaedrux
I think that was it! I see so many people using fan mounts similar to this one so i didn't suspect it could cause issues, possibly they are mostly using v2 effectors? Either way ill take it for what it is and get everything going. Thanks for the fast responses and time helping!I sent an M672 S131:131, and rebooted but don't see 2 start up blinks, just one, not sure that is to important.
Thanks!Bellow is the super probe script now.

the one blink sounds like my board is in factory test mode?
"1 flash - normal startup in test mode - for factory testing only"
From the guide. -
Not exactly sure what i did, but after several default settings commands its blinking twice on startup, and running around a 10micron SD with 50 sens.
Going to try and get it all running and configured to print at this point. thanks!
