To upgrade machines in Oritech, addons are used. They are blocks that need to be attached to the machine itself or a connected machine extender. Addons can perform a variety of functions, such as increasing speed, improving energy efficiency, providing access to specific inventory slots, and more.
Machines can only accept addons at specific positions. To view these, either check the "addons" UI page or look for these markers on the machine:
Addons are activated when the machine is right-clicked. To indicate activation, the pink parts of an addon turn blue when in use. To extend the available number of addon slots, you can use machine extenders. These specific addons don't directly influence the machine but allow addons to be placed on them, which then count towards the machine they are connected to.
The maximum layers of machine extenders you can use depends on the machine quality. If you have a machine with a core quality of 1, you can't use any extender. Each additional extender that goes through another extender requires an increase in core quality of 1.
The core quality never directly counts the number of machine extenders you have active. Instead, it counts through how many extenders an addon has to pass to be connected to the machine. If this number is greater than the core quality, the addon will not be connected. See this image for a small demonstration:
As mentioned before, only the number of extenders between a machine and an addon is counted. This means you can branch the extenders, and everything will work:
