5.2 Connecting OpenBuilds Interface to other Grbl controllers
The OpenBuilds Interface can be wired to almost any Grbl 1.1 based CNC controller if it has a UART to connect to.
You will likely need to make up / modify your own cabling, the included cable is designed to be a direct fit for OpenBuilds BlackBox.
Pinout
| Pin on Interface's BlackBox connector | Pin on your controller | Notes |
