Smart effector flashing six times

[Andy_M]

I have tried resetting the sensitivity to factory settings but the board is still flashing 6 times continually.

Sorry, only part reply as I was struggling to log on yesterday - technology is working well for me it would seem. I have recently updated the firmware to the latest stable version 3.4.0 and I am also, successfully running another delta with the same set up so I don't think it I have done anything crazy.

When did you purchase from oozenest?

Can you disassemble the smart effector and snap some close up photos of both sides?

[Andy_M]

@phaedrux Will do.

@andy_m
Looks like there is some damage to the traces near the heater output

[Andy_M]

@jay_s_uk Yes I noticed that, doesn't look like the tracks are damaged, just the blue cover but then they also look very delicate.

[jay_s_uk]

@andy_m they are in the V2 version. The be version uses resistors rather than traces to measure impact and is a lot more resistant to damage. Have to wait for @Phaedrux to determine the next steps

[Phaedrux]

The damage to those traces looks like it could be the problem. They are quite delicate. Waiting to see what DC42 thinks.

Do you know what caused that scuff? I assume it worked at some point?

[Andy_M]

@phaedrux It was working fine, I'm not sure why, but the fan mount broke. (I work in a school and some of the students can be a little unreliable!) I think refitting the fan must have caused the problem, there isn't a great deal of space. I have another board like this, would it cause a problem if I covered the board with tape if I have to replace anything? Don't want to trash another one!

[Phaedrux]

DC42 has confirmed that the damage is likely the problem. The traces are quite delicate.

You mean as protection for the traces on the new smart effector? I suppose that could work. It probably wouldn't make it stiff enough to matter. Worth trying.

[Andy_M]

@phaedrux Okay, thanks for your help identifying the problem. Is there a newer version now, @jay_s_uk seems to suggest so and it looks different on the Duet product pages?

[jay_s_uk]

@andy_m yes, theres a v3. I have a couple

[Andy_M]

@jay_s_uk Do you know where I can get one that doesn't include the hot end as I don't need the extra expense? They are listed as out of stock on the Duet site and Ooznest is the v2.

@andy_m Sorry, found it on E3D
