Ever wanted to create your own DIY 3D printer monitoring solution? In this project I'll just do that! It allows you to monitor power consumption and voltages all with the ESP32 inside it!

GitLab: gitlab.com/timkoers/printer-controls

Please note to align the 38 Pin DEVKIT V1 with the front of the pin headers, there will be 2 pins sticking out of the back, but it should be compatible.
