I'm trying to send a full Teleported pr Science from Fulgora to Nauvis.
Power limits:
Fulgora: 23.4Gj
Nauvis: 102 Gj (Solar only if that matters?)

I've only got two teleporters. both with the link ID , The symbol for the science bottle from Fulgora (electromagnetic Science)

The teleports fail. No beacons are near either teleporter, I do have an inserter trying to place items in the teleporter even though it's full. But that's the same as an assember etc..

Thoughts on why it's not beaming?

I'm a fool.. the Nauvis one was not powered.. Rookie mistake.. I'll go play with this more now.. cheers!
(Can I add them to space platforms too?

I'm glad you figured it out! Debug mode can help diagnose problems, if you aren't using it already.

You can't put the teleporters on space platforms. There are some valid gameplay reasons for this but mostly I didn't feel like doing the extra work to implement destinations that aren't planets.
