Was playing a game and decided to add Pelagos mid-way. My ships are now "stuck" as they can't access fulgora anymore (Pelagos access is locked behind Gleba which i haven't completed yet).

Is there a mod setting I can change to move Fulgora reachable to Nauvis?

Figured it out, managed to reposition as below if anyone wants to mirror it:
"Enable space connections redrawing" turned off/unchecked.
Fulgora Radius 23, Angle 52. This puts it top left of Nauvis at 16,000km like Gleba and Vulcanus. It also creates a connection from Fulgora to Gleba, mirroring the Space-Age non modded connections.

Optional:
Rubia I put the radius at 21, the default value of 30 had it appearing in the asteroid belt with Star Map background mod. This creates a connection between it and Nauvis, allowing you to travel to Aquilo quicker. (The author seemed to be doing a radius of 2 between large planets so tried keeping that approach)
Lignumis I put angle of 340to fit nicely between the new connections for text readability.
Muluna angle of 20 for same reason above.

Good job. Glad that you figured it out by yourself. Better Planets is very tweakable, so you can set everything for yourself as you like

A couple of things I noted:

When disabling "enable space connections redrawing", the additional asteroid belts don't connect to each other. (Only the aquilo side ones are connected)

I'm assuming this setting is for allowing you to move moons or other combined planets away from each other and not have forced connections. Maybe renaming it "Disable fixed moon connections" might be clearer that it's those that are being removed. I thought it was you had to disable it to have any planet be moved and form new connections.

For Better StarMap Background mod, if I do "Enable Inner Asteroid Belt" it creates one a lot bigger than the default which made the locations of the belt entrances and planets look wrong. I would mention to disable it in the description, or you can force it off in your own code (Factorio API allows you to change settings of other mods https://wiki.factorio.com/Tutorial:Mod_settings#Changing_another_mod's_settings)
