Dondolo Electric Box

This electric box is for connecting the servo, 2 Hotend Fan's and a printer fan on a Ramps 1.4 board. The Fan's are using PWM from Servoports D4, D5 and D6. The servo is connected to port D11. The guide is original from the D.E.I.S.S Extruder https://www.thingiverse.com/thing:651723

The PCB is drawn in Target 3001. I have milled it on my CNC milling cutter.


The box is mounted above the servo

Setup electronics
The servo needs to be powerful enough to move the engine and provide the torque to move it against the spring of the levers. The RAMPs (the Arduino Mega) is a very powerful, powerful, and easy-to-use tool that can be used in a wide range of applications. This could be done by adding a 5V regulator which is directly driven by the 12V power supply. I created a small hand soldered PCB which also expands the D4 to D6 to drive a fan. The schematics are shown below. From this PCB, the servo is supplied with 5V as well as the servo signa
