Tandem Z axis suddenly homing in opposite directions

Okay, I will read up on halmeter tonight and see what fresh hell I'm getting into.

Tried sifting through documentation and youtube the latter of which was unhelpful. I'm not fully understanding halscope but I managed to get to a point that I found the home-z and home-z2 and found that the z2 was true even though it wasn't tripped. Tripping it on and off yeilded sporadic results while home-z was consistent and toggled correctly. Swapped out the switches and now it homes in the proper direction.

Kudo's to you all. It seems like CMorley hit the nail on the head as well but I really appreciate the guidance you guys have all given!

Thank you so much!

Do you have two independent Z axisor a single Z axis with two motors driving it (dual drive like a gantry)?
