Testing the controller

A project log for DIY Inkjet Head

This is my attempt to build a simple inkjet head that everyone can build at home.

For the 9 nozzle printhead I want to use the Ramps 1.4 + Arduino Mega 2560 as controller too but the M106 command supports only 3 "fans" at the moment.

So I used the I2C connection to connect an Arduino UNO which drives the LEDs and later the L298N H-bridges. The same UNO can create the H-bridge direction change too.
