Factorio Forums

Hi I am using newest version 2.0.12 and only the factorio mods,
I researched the technology but I can't produce the red or green wire.

green and red wire have moved to the shortcuts alt+g and alt+r
Might also be worth mentioning that copper cabling electric poles can be done with alt+c now too

Not a bug, they were removed as items for 2.0. You can find them as virtual items at the right side of the hotbar, together with other actions, like the Alt mode toggle, copy/paste, undo/redo, etc.

If you wish, you can click the buttons, then click a hotbar slot to assign them there for use with number keys. (On the hotbar, they are then displayed with the traditional red/green wire symbol.)
