If I switch on my printer, it's very likely that I want to print something. This is a simple and adjustable gcode script that will automatically start when the machine is switched on with the SD card in it. It will play a sound and move the printhead to the right and the front as a indication that you are using the pre-heat script. Then it will heat up you nozzle and your printbed. In the meanwhile you can start a print. If you don't start a print within 10 minutes the machine will play a sound, cooldown and reset the printhead position. Tested on the UM2
