Ultimate Marlin 2 + BLTouch for Ender 3 with OctoPrint

This is the vanilla version of Marlin Firmware 2.x pre-configured for Creality Ender 3 printers with original or generic BL Touch sensors. This distribution is focused on professional/power users and is packed with the maximum amount of features the small 1284P chip can fit at the expense of the SD Card support. Because of the lack of the SD support this is only recommended for OctoPrint users.

Control Arduino via USB OTG from Android

This script allows Johnny-Five to run from a Termux terminal communicating with other Android apps or external devices by using the TCP protocol without root, without bluetooth and without the WiFi shield. The reason for the TCP protocol is that Termux still does not implement USB-OTG to Serial drivers and the vanilla Johnny-Five would hang right out the box because of this limitation.
