I see the original thread with the same title was locked, without a reason or solution.

I'm facing the same starter issue on copper. What's the solution for copper in starter phase? Or is this mod no longer maintained so we'd actually give up the run?

The old thread was locked because it was getting out of hand.

In the beginning you are to sort ash for copper using the generic then specific recipes, then eventually transferring to Cadaveric Arums.

Or is this mod no longer maintained so we'd actually give up the run?

Updated last month is not "no longer maintained". This mod is in active development. The current content version has the level of balance I'm looking for. I'm working on a major content update to refactor the early game. There is no ETA for it.

After idling for 15 hours I kinda just gave up, made 966 copper plates total , unclear how to even get more ash since everything that can produce ash is already going constantly

I believe I am using the specific recipe that gives 8 copper ore
This is a gajillion times worse than original seablock

As dev already responded and as per announcement:
"PLEASE READ
Yes, this mod is in active development. No, it is not abandoned. Yes, the balance is as intended for the current content. This is a -block mod. It's not designed to be fast, nor easy at the beginning. It's supposed to be a challenge. Belts too expensive? Then use less belts, walk around a bit. Still too expensive? AFK is an option. "

From myself you do not need THAT much of a copper prior you can make a lot of it.
