I'm playing 0.12.1 and I can't figure out how to get any drills on to cerys. I can't drop anything but bots, and I need planet specific resources to craft every other drill.

For now I just cheated in an electric mining drill via /editor, but I would prefer not to do that.

You can drop coconuts thanks to coconut drop technology
That will allow to make sealant
That will allow to make diesel drills powered by methane or light oil.
They also don't freeze

Wait don't I need biochambers to make sealant?

You never needed them to make sealant even outside ships of fools.

They just provide you prod bonus

Yeah you're right. Really been enjoying this mod. Maybe I didn't have chemical plant at the beginning of the mod or I had to unlock something.

Trying to figure out how to get consistent power on cerys, but it is very non-obvious to me. I can't craft accumulators. To make boilers for a heating tower I need stone, but there is no stone.

Happy that you enjoy. Cerys have its own accumular thing.
Forgot a name but it look similar to powerpole/lightning rod

Also. My diesel assemblers and inserters don't freeze so you could drop more coconuts to make factory less electric dependant.

You still need to complete cerys puzzle but my machines could help you a bit outside of its scope
