 At the time of me writing this program, Marlin had a bug that caused the manual mesh bed leveling process to not work using the connected LCD display, leaving G-Codes sent over the serial port as the only option.
 Because manually inserting these in a terminal program proved to be very tedious, and none of the G-Code senders I've tested had the features I wanted (mainly easily configurable step sizes), I wrote this simple little program.

 This has been developed and tested on a Mac OS X 10.10.5 machine with Python 2.7 and dependencies installed with MacPorts, connected to a modified Fabrikator Mini V1.5 with Marlin 1.1.0-RC6.

+You need to enter the hostnames / IPs and the OctoPrint API keys of your printers in the settings dialog of the application.
 The program will automatically detect which method to use to switch the power.
 If you are using the [PSU Control OctoPrint Plugin](https://plugins.octoprint.org/plugins/psucontrol/) it will use that to toggle the power.

 To give you an example of the system actions you could use to switch GPIOs from OctoPrint, take a look below at the excerpt of my 'config.yaml' file.

 Since moving into my own flat in 2019 I started growing quite a bunch of plants.
 It started with carnivorous plants and some decorative stuff on the balcony (also good for the insects!).
 Last year some herbs like basil were added.
