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.

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

@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

More feedback:

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.

Thanks, Andrew

@droftarts said in Smart Effector LED indicator:

@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.

Hi,

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.

Cheers, Andrew

David,

Is Zin - AD12 on the wiring diagram? From here, http://www.reprap.org/wiki/Duet_Wiring

P1 it is, as simple as that! I get 920 when triggered and 0 when not.

The probe is probing away - the end of the probe is a little high - nozzle is hitting the bed at some points, but I am super excited to see the probe in action!! It has been a few months of trying things, mistakenly putting the servo signal in pin 19, didn't help either.

Regards, Andrew

Hi Everyone,

First of all thanks to everyone that posts here. I finally got me wiring correct and learnt about the S60 test mode. Unfortunately, what to do when S60 does not produce a 0 value is not covered anywhere, that I have found.

Getting my BLTouch to register that the probe has been triggered on my Duet 0.8.5 board is where I am currently at and looking for advice.

Connected the servo leads to pins 1, 2 and 21.
Probe leads, White - Zin/ AD12 and Black - GND.

Config.g is setup as:
M307 H3 A-1 C-1 D-1 ; reserve heater 3 (pin for BLTouch PWM
M558 P5 X0 Y0 Z0 H5 F100 T2000 ; Z0 for delta
G31 X0 Y0 Z0.3 P25 ; Set the probe XY offset, Z height and signal threshold

BLTouch retracts and deploys twice on power cycle and Red LED stays lit.

When deployed:
M280 P3 S10 I1; Red LED is unlit, Probe extended and Prove voltage in 0 v
M119 ;Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop
DWC - Z Probe Red 1000 value

When in test mode and probe triggered:
M280 P3 S60 I1; Red LED is lit, probe stays up, Probe voltage is 2.9 v
M119 ;Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop
DWC - Z Probe Red 1000 value

Expected behaviour:
M119 - should show Z probe triggered
DWC Z Probe value should be 0

Question:

Is the Z Probe voltage of 2.9 v too low for the Duet electronics to register that the Z Probe has been triggered? If, so, then what trigger voltage is required for the Z Probe?

Additionally, is there a "pull-up" resistor that needs to be set on the Z-Probe in config.g that I am not setting that is causing this behaviour?

Firmware Version: 1.19beta10+2 (2017-07-20)
Web Interface Version: 1.17+1
