Bump to the top.... I have Tom's ReCube Pro. It works great and does exactly what it's supposed to do. With this software you can change the chip to PLA, ABS, Nylon, whatever the printer can handle. Able to change the color name of the filament also. No more buying cartridges when you need only need the chip. Use what you have. Since the hack is chip based and not firmware specific it works on Cube3, CubePro and possibly the Eco. Runs on the Arduino 328 processor. Any board having this processor chip will work. I used it on a Pi Ala mode, piggybacked on a RasberryPI 3 running Linux. NP. I highly recommend it. G70
