Techtonica is a first-person factory automation game set beneath the surface of an alien planet. In this game, players can work alone or in co-op to build factories, gather resources, research new technologies, mold the destructible terrain, establish a base of operations, and uncover long-forgotten secrets.


In the game Techtonica, players are encountering an issue where they cannot assign any new items like High Voltage Cables with any toolbar key. This bug has been reported in the Techtonica General Discussions. Players have also mentioned their confusion with the usage of Voltage Steppers. This article aims to address these issues and provide solutions.

The Bug: Cannot assign any new items with toolbar key

One of the reported bugs is the inability to assign new items like High Voltage Cables with any toolbar key. Players have attempted to assign these items using different methods, but they have been unsuccessful. They have also mentioned that they have followed the in-game guide, but still cannot connect the Voltage Steppers.

The bug seems to be persistent even when players have ample amounts of High Voltage Cables in their inventory. This limitation in utilizing the desired items on the toolbar has caused frustration among players.

Possible Solutions

While the bug is still being investigated by the Techtonica development team, there are a few workarounds and suggestions that players can try.

1. Click and Drag to Toolbar

One user reported that although they couldn’t assign High Voltage Cables with a toolbar key, they were able to click and drag the cables to a toolbar slot. This method might allow players to access the desired items without the need for assigning them to specific keys.

2. Empty Inventory

Another player mentioned that they were able to add and remove High Voltage Cables after emptying out enough items from their inventory. This suggests that the issue might be related to inventory weight or capacity. Players can try reducing their inventory load and see if it allows them to assign the desired items to the toolbar.

3. Check for Prerequisites

It is possible that there might be certain prerequisites or tasks that need to be performed before being allowed to connect the Voltage Steppers or other items. Players should ensure that they have fulfilled any necessary requirements in order to progress in the game.

4. Seek Help and Share Feedback

If none of the above solutions work, players are encouraged to seek help from the Techtonica community. The Techtonica General Discussions forum is a great place to share your experience and ask for assistance. By providing detailed information about the issue, players can help the development team identify and fix the bug more efficiently.


In conclusion, the inability to assign new items like High Voltage Cables with toolbar keys is a known bug in the game Techtonica. While the developers are working on a fix, players can try alternative methods like clicking and dragging the items to the toolbar, emptying their inventory, and checking for any prerequisites. Seeking help from the Techtonica community is also advised. By working together and providing feedback, players can contribute to the improvement of Techtonica and ensure a better gaming experience for everyone.
