Repetier Server Monitor for 3D printer

thingiverse

Modified version of great Qrome's Octoprint Monitor (https://github.com/Qrome/printer-monitor) Modifications: - ported to Repetier Server monitoring - different hardware - ESP-12 board, USB & Li-ion battery powered - added speaker for acoustic notification of finished print - different 3D printed box Source Arduino code, Eagle PCB design and Inventor model attached for further improvements. Youtube video: https://youtu.be/Qzp1GBK4jTI The box is designed to be able to print without supports. Lock1 and Lock2 parts are fixed together using a small piece of 1.75mm filament. The lock is used to push on/off push button. There definitely can be a better design for on/off switch but I just did not have self locking pushbutton by hand. New configuration menu items: - Play melody when print is finished - on/off checkbox - Play melody X seconds before the print is finished - how many seconds before the print is finished the melody is played. Value 0 means right when print is finished. - Battery voltage multiplier - battery voltage is measured using ADC pin and voltage divider. Measured value (0 - 1024) is multiplied by this constant and divided by 1000. The value is displayed at home page and it is used for battery gauge.
