      Hey there,

      my name is René and i have purchased a smart effector for my delta printer. During the assembly i notived that there is a small gap (nearly 0.4mm) all around the PCB and the E3D Heat. My question is: Is this ok? or shopuld i tighten the Hexnut with more power to close the gap? I dont won't to break any of the fine traces there so i am a bit concernd if i can give the Nut more torque. Are there any recomandations regarding the torque?

      Best regards
      René

        It's easier to know when you show a photo of your issue, I have a hard time understanding where the gap is. The heatsink should be stable, but the nut should not be torqued too much as that can cause spurious triggers of the strain gauge.

          Please see the smal gap between the first,smaller Ring and the PCB. I think the both opposed flats should have contact?

            IIRC; there is a small upper ring on top of the threaded heatsink that should fit into the hole in the smart effector. I would try removing the nut from the top and aligning and pushing in that ring carefully, then putting the nut back on.

              i tried that first. i pushed it as much as i dared it but the gaps will not close. So i thought maybe with the nut in place it will be better but no chance. Not sure but will have it an effect on the System when this gap will stay there?

                There is a small step at the top of the E3D heatsink. So it's normal that the small top heatsink fin doesn't touch the effector PCB.
