Opz line module

Hello hope someone can help. I bought a line module about a month ago but today I went to use it and my opz can’t see it. I’ve tried taking it out and putting it in again but other than that I do t have any ideas. Has anyone had the same problem? Thanks.

Wondering if the pins may be dirty? Do you have any Deoxit or something similar?

On my Oplab, I had to have a small piece of foam on top of it to wedge it into place and sustain good contact

Did you turn the screw thing to lock it in? I don’t think it is recognized unless that is done.

Is your firmware up to date? That could be why the OP-Z doesn’t see the module.
