I can no longer remove the end cap on the cylinder, nor take the cylinder off the wired endcap. I’m a little worried about...

Thanks Brian and Tamanya. I got it open using an old (not super sharp) knife and wiggling the blade in, as per Brian’s suggestion with the flathead screwdriver ( I didn’t have any with a thin enough head).

Did you ever get this worked out? When I typically have these problems it’s because I didn’t change my computer network settings. I use a mac, and have a location set up specifically for “OpenROV Expedition” which focuses on the thunderbolt connection. Just last weekend I was having a similar issue, and realized I had not hit the “apply” button to actually use it.

It's a little unclear what is being glued here. is it the second cylinder past the gap (where the first cylinder is the focus part?) and then pushing it in?

I assume blistering the wires with the heat gun is a bad thing because it might expose the wire underneath -- maybe a warning hear about that?

It's not completely clear from this picture.... I think the hole is not supposed to be filled, is that correct?
