Help!
-
That appears to be the nut holding the zesty nimble mount to the board.
-
Which raises a question of why there are mounting holes close enough to sensitive traces that a nut would then rest on them haha.
-
Balance of making the effector huge to leave space for very large nuts.
What looks like damage around the hole at the bottom of the picture is close to the hike and does not appear to impinge on the traces.
The damage around the hole in the top left looks quite spread out and does impinge on the tracks. That looks like tool marks to meet but it's hard to say from a picture.
-
Ah, interesting. That sounds right. I ordered my replacement board already, should be here soon enough I suppose.
-
If you are going to use the extra fixing holes, you should always have a plastic part (e.g. nylon washer or printed part) on both sides.
I can't tell from the photo whether the strain gauge traces have been damaged. You may be able to tell if you look at it under magnification. However, if the sensor works when the magnetic arms are not attached, I suspect that the problem lies elsewhere. Do all the SMD components look securely soldered on?
-
I'm at work at the moment but I'll give it a thorough look when I get home. I gave it a once over before and didn't see damage excepting what I posted earlier. I was unable to replicate it working without magnets attached however; it was non-responsive with or without magnets the second go-round.
-
Would kapton tape interfere with the operability of the strain gauge? It could help protect the traces.
-
Kapton tape shouldn't interfere with it.

Well sh!t!
My replacement effector doesn't work either! Only options= cables or config.g - Cables worked well enough to set the sensitivity, so what am I missing!?!
-
Are you saying that with your new effector, the green led doesn't flash if you give the nozzle a sharp tap upwards?
Could it be that there are metal parts in your assembly that are touching the components on the underside not the board?
