OctoPrint-Lcd1602

PYTHON3

This plug-in allows you to control a 16X2 lcd display (hd44780 connected to port I2C) to display the octoprint status. If DisplayLayerProgress is installed it is also possible to display the current layer count.

It is useful for people like me who have a printer without a display. It indicates on which port the printer is connected, the progress of printing. It also displays the remaining print time (thanks to a simple method).
