This machine is designed for Jobo 1520 film development tanks. Additionally to the printed parts you need:
I used the ZK-SMC02 motor driver programs P03 for continuos rotation and P06 for inversion rotation.
If someone want's do create a ESP32 board for controlling the stepper motor, contact me. I was just to lazy to design a driver board and write software to control the machine. But a wifi controlled Filmshaker with web frontend or app would be a cool thing. 😅
The author marked this model as their own original creation.
