Artemis probing issues

[scabbermatt]

I am hoping someone might be able to assist me figuring out what this missing piece on my SE300 Probing circuit board is I can see that there was something mounted there before.. And since bed leveling/probing was hit or miss the part had weak solder joints and got knocked off the board at some point and is lost to me.. I am a new 3d hobbyist that got lucky and found an Artemis for $100 cant really afford to buy a new board but I could swing the cost of the part from digikey if I knew what it was. I have the abilities and know how to repair the board. just need the part specs

thanks in advance
hoping this isnt the coolest $100 paperweight in my shop for long

Well after what seems to be a successful board repair... Looks like maybe the stress sensor/effector just has other issues as well possibly. Still getting the errors from before it died of - the probe results being "inconsistent".

When I try to do the bed leveling it moves down, towards the back then immediately after first probe (moving down) it seems to slip(?) further out then it does the same type of stutter on most of the rest of the probe points. One or two seeming normal then finishing with some not even contacting.

any help would be very much appreciated

thanks in advance

it seems like a config issue but I am new to Delta printers so maybe some of the Hardware needs replaced?
