In the June Sol One demo, smelting requires raw material, a powered smelter, a selected recipe, and enough heat for that recipe. Simply bringing ore to the machine does not complete the process. Check those conditions separately before spending more resources on a machine that is only missing power or the required temperature.

Prepare the material and power connection

The June Next Fest player playthrough follows the basic production chain: mine nearby material, collect it, and bring it back for processing. The player initially tries to progress with a smelter that is disconnected.

They then use wire placement to connect the smelter to the battery. That connection allows the processing steps to continue.

For this recorded demo workflow:

  1. Mine and collect the raw material you intend to process.
  2. Check that the smelter has an electrical connection.
  3. Supply the appropriate material to the smelter.
  4. Use the machine’s recipe information to determine what it can process.

Power is an enabling condition, not the finished result. Once the machine is connected, its recipe and heat settings still matter.

Select a recipe and meet its heat requirement

The player selects the relevant processing option and adjusts the smelter’s heat to reach the requirement shown for that operation. The commentary makes clear that the displayed requirement is a threshold to meet, rather than proof that every material can be processed at the same setting.

Use the value shown by the recipe in your own build. The transcript contains ambiguous spoken temperatures and uncertain commentary, so reproducing those numbers would be less useful than reading the machine’s actual requirement.

If processing does not begin, work through the conditions in order:

  • Is the machine connected to power?
  • Has it received the required raw input?
  • Have you selected the intended recipe?
  • Has the smelter reached the heat that recipe requires?

This checklist comes from the recorded demo process. It is not a promise that it fixes every possible issue in another version.

Use processed output in the next manufacturing stage

The official Sol One Steam listing describes three production stages: extraction, processing, and fabrication. Smelting belongs in the transition from mined material toward usable manufacturing inputs.

The demo player uses processed copper in the Fabricator to produce wire. That illustrates why getting the first smelter powered matters: additional electrical connections may themselves depend on material you cannot fabricate directly from the raw input.

Do not confuse the two machines. The smelter processes suitable raw materials; the Fabricator produces tools and components from processed materials. The developer’s October update also describes refined components supporting more advanced crafting.

What to recheck in later versions

The October 9 developer update changes how a new smelter reaches your base: smaller equipment is produced by the Fabricator as a physical crate that you carry and place.

That is different from the earlier demo’s equipment-building behavior. It does not establish that every smelting recipe, timer, or temperature remains identical. As of the November 12 source check, Steam lists the Early Access release as planned for November 13, 2026; this guide does not claim personal testing of that launch build.

Use the recorded demo steps to understand the dependencies, then read the installed machine’s actual recipe and heat information.

FAQ

Why does my demo smelter not start after I bring it ore?

The recorded process also requires electricity, a selected recipe, and sufficient heat. Check each condition rather than assuming the input alone starts processing.

What exact temperature should I use?

Use the requirement displayed for the selected recipe. The obtained transcript does not provide a sufficiently clear universal temperature table.

Can the Fabricator replace the smelter?

The sources describe different stages. In the demo example, raw material is processed first, and the resulting copper is used in Fabricator production.

How do I obtain a new smelter in the later announced system?

The October update lists smelters among the equipment fabricated as physical crates that must be carried and placed.
