<p>This thing was made with Tinkercad. Edit it online <a href="https://tinkercad.com/things/g1vFJBOX838">https://tinkercad.com/things/g1vFJBOX838</a></p> <p>Use this to monitor 2 power supplies ,both volts and amps Two temperatures, extruder and print bed in both Fahrenheit and centigrade. Two LEDs indicate power to heaters.</p> <p>The. Arduino code is in thing files</p> <h3>Instructions</h3> <p>I used a 2004 LCD display, 2 DS 18B20 temp sensors, 1 AC-712 5 amp sensor,1 AS-GY-712 20 amp sensor, a Moderndevices RBBB UNO clone, 2 voltage dividers made of 1-10k resistor &amp; 1- 20k trim pot, 2 LEDS and a few connectors. Then I created the code in Arduino a little tweaking here and there and this is the result. The extruder temp is low because the sensor just rests on the top of extruder so this is just a reference reading not actual temp (DS 18B20 only reads to 125 C). In the code is a place I added a fudge factor to get a better idea of extruder temperature there is one for bed temp also.</p> <p>The bed sensor is stuck to the bottom of the bed heater. The 2 LEDS are connected to the heating elements wiring, they indicate when power is flowing to the heaters (good for trouble shooting heater problems &amp; I just like blinking LEDs). I use 2 separate power supplies, one for the Arduino,stepper motors, fans and lights . I used solid state relays for the extruder heater and the bed heater they have their own power supply . Neo magnets hold display case to cabinet so I can position it as I need. Arduino code is included in thing files</p> Category: 3D Printers
