Flexystruder Hot End vs Standard Hot End

I was doing some work on my flexystruder this weekend and noticed it has an extra (something) on the left side of the main block. Can anyone tell me what this something is?

Not without a picture. It’s possible it’s the screw for attaching conductive auto leveling as used in the Mini.

It’s a wire of some form with a blade connector on the end and a screw through it. I’ll see if I can’t grab a picture tonight.

Thats most likely the lead for auto leveling. It’s shown as "ground lug in step 7 here: https://ohai.lulzbot.com/project/cf3b0638-1e1e-4bff-a00e-c3308d914c68/mini/ but what it does is tell the mini version of the hotend when it has contacted the auto leveling washers. You can safely leave it or remove it.
