Smart Effector LED indicator
I recently installed the Smart Effector and am busy with the commissioning on an AnyCubic Kossel Linear Pro (2017) Delta with Trigorilla v1. board, running klipper software using OctoPrint (1.3.12) via octopi (0.17.0) on a raspberry Pi 4B 4Gb.
I do not get the status LED to show up on the Smart Effector when the printer starts or the board resets when restarting the klipper host server.
Things that are working:
- The thermistor is responding - I get a thermal error when the Input2 plug is removed
- The orange heating LED is glowing on the Smart Effector when the hotend is powered. The onboard blue LED also flashes on the Trigorilla.
Things I have done so far to diagnose my problem:
- Continuity tested the wiring of Input 2
- Confirmed GND and VCC voltage of 4.83v
Whilst continuity testing I found that one of the fan pins on the 6pin connector is faulty - so that plug is removed at the moment - whilst i gather the strength to take the DuPont connectors on my dodgy crimping tool. Mega patience is required. I will continuity test each wire before installing in to the 6-way plug.
Does the status LED only become visible when the calibration probe routine is initialised by the firmware or when the Trigorilla board is powered?
Any other troubleshooting advice that I can follow to resolve the no LED on the Smart Effector board would be appreciated. The Smart Effector wiki only mentions LED status codes that are flashing, but not when no LED is light.

You should get a flashing LED at power up; if not, most likely either the VCC or GND on INPUT2 is not connected. Check wires and connections between these.
@droftarts - thanks for the links - I was following those.
As I mentioned I have 4.83v across VCC and GND at Input2 connector, but no LED status lights are flashing on power up.
@bassco Which Smart Effector do you have, v1.3 or v2? I just did a quick test with an unconnected Smart Effector v2 board. I applied 5V from a wall wart to VCC, GND back to the barrel connector (I'd post a picture but too embarrassed by how it looks, with wire poked into the barrel jack!). Waited 3 seconds, then got 6 or 7 flashes, twice. Subsequent power cycles I got two flashes. Referring to this guide, that's normal: https://duet3d.dozuki.com/Wiki/Smart_effector_and_carriage_adapters_for_delta_printer#Section_Troubleshooting_LED_flash_codes
This was with nothing else connected. Can you try something similar? Waiting 3 seconds is crucial, too.

6 way connector repaired and all connections are now passing on the continuity tester.
Powering the board still has NO flashing status LED
M106 S255 (Hotend fan) - Corner LEDs are lit, fan is on
@droftarts - I have a V2 - will try with a dedicated 5v supply and look for the flashes.
@droftarts - success from a separate 5.01v supply.
On power up - got a few 6 flash sequences, then 2 flashes and then all out - normal behaviour according to the wiki - progress
Rechecked the Input2 source power lead to find that i had switched Vcc, Gnd and Signal at the endstop position of the board.
I now have the 2 flash LED sequence on power up.
Thanks for the troubleshooting ideas @droftarts
The probe is working like a charm.
The most magnificent first layers I have ever experienced.
Thanks @dc42 and the rest of team for an amazing piece of kit.
@bassco Great! Glad it's working well for you.

@bassco How did you configure the Smart Effector for Klipper?
I can't seem to find any info on it
This is my current config:
[probe] pin: PC1 z_offset: -0.1
The wiring was okay and was in working order before going Klipper, so that's not a problem.
