Hello,
I've recently fought against the Motherboard as the first mechanichal boss with a pretty "normal" equipment for that point (Orichalcum melee set) and, with around 55-60 defense, I could easily tank the motherboard as soon as it's "opened". That's because the motherboard has a way too low contact damage and it charges directly to you, so I can just stand on the ground getting 1-5 dmg from the Motherboard and overwhelm it with melee attacks.
Because of how invencibility after receiving damage works in Terraria, only the Motherboard damages me (the little drones attacks don't hit me) and it makes me almost no damage, making it an extremely easy boss compared with the rest of the mechanical bosses.
So I'd suggest you to balance the Motherboard by increasing it's contact damage or, if possible, improving it's AI to focus on hitting you with it's laser rays.

I got one Motherboard summoning item from a random drop on a Bloodmoon. You could also create a crimson world to get a few vertebrae.soooo, my world has corruption, does that mean i can't summon motherboard in any way?
i'm playing whit a mod that ads a NPC who sells vertebraes, so i can make the summon item.
