Here is a test of the Toolhead.
This is my attempt to build an open source inkjet printhead by myself. I started this project because I wanted to build a binder jetting 3D printer but could not find any open source inkjet printhead for this. So I started trying to build one.
The toolhead is a DIY Piezo Printhead inspired by https://reprap.org/forum/read.php?153,52959,page=1 and https://reprap.org/wiki/Reprappable-inkjet.
It's controlled via a L298N H-Bridge and PWM from the 3D printer. The printhead runs on 36V DC and the puls is created by an Arduino Uno.
The first test was engraving / printing the rose made with Estlcam. The second test was Bob Marley as dot matrix with Pixels to Gcode on 80g/m² paper which seems to be too thin. Today I tryed with 120g/m² paper and it works way better. Pictures and more tests with dot matrix will follow.
