Random Smart Effector flashes

@T3P3Tony am using SKR 1.4 Turbo not duet , so my MOD pin is not connected to anything right now ,

let me just explain what is the issue i see , the smart effector works fine and do auto claib and all is good but all of sudden it start to flash even if its not doing anything , if i reboot the printer and it become normal again

@bearer that is exact what i messuered i wish you put that first lool but i found it with my cheap microscope

shouldn't listen to random strangers on the internet; btw I've got candy!

(sorry, I just randombly stumped onto the post where it was assumed damaged, and worked back to look at a way to verify as repairs seemed unlikely)

@T3P3Tony so what do you think it is ?

dc42

Does it make any difference (to the random flashes) whether the motors are energised or not?

Does it make any difference whether the heated bed is on or off, or how close to the bed the effector is?

If you remove the effector from the printer, apply 3.3V or 5V to the Vcc and ground connections of the white 8-pin connector with nothing else connected, does the green LED still flash randomly when the effector is still?

@dc42 i tried that and no flashing , i just did now auto delta calibration and went fine

G32
Calibrated 8 factors using 16 points, (mean, deviation) before (-0.174, 0.045) after (-0.000, 0.021)
Auto calibration successful, deviation 0.021mm

then did mesh level and it stopped saying

G29
Error: Z probe already triggered before probing move started

then i just reboot the printer then i did G32

G32
Calibrated 8 factors using 16 points, (mean, deviation) before (-0.212, 0.042) after (0.000, 0.019)
Auto calibration successful, deviation 0.019mm

and then mesh 170/30

G29
101 points probed, min error -0.571, max error 0.685, mean 0.033, deviation 0.242
Height map saved to file heightmap.csv

so it does it every 2nd time i ask for mesh g29

its random

I presume you mean that when the effector is connected to 5V or 3.3V only, the random flashing ceases. That suggests that the problem is either mechanical interference (i.e. vibration - which is why I asked if turning the motors off made a difference) or electrical interference (most likely from stray magnetic fields - hence my question about the bed heater).

Do you have an extruder mounted on the effector, or is it a bowden system?

sankafola

@dc42 its flaying extruder with 20 cm tube , the thing is if its the bed electromagnet it should affect it all the time not just random , here is my setup

dc42

Does the random flashing stop when you raise the effector well above the bed?

sankafola

@dc42 no the random can happen also while its home which is very far from the bed

the light shown is that led's on/near the effector? does it help to turn lights off?

sankafola

these lights of the smart effector why turn off? you think its related to the random flash ?

was just thinking if they were external leds and you're looking for a source of noise, it'd be worth looking into.

sankafola

its built in LED in the smart effector and i dont think its related because they are on while its working normal too its built that way

sankafola

@dc42 just to be sure the LED which flash random is the same LED which flashes 2 times when it turn on the printer

sankafola

@dc42 what do you think ? do you think the smart effector the card itself have something wrong ?

@Phaedrux thank you will do
