suite à une discussion sur l'irc smoothieboard
''12:11:00 - Triffid_Hunter : cedriko: should be a file, firmware.cur or similar on your sd card. save it somewhere, then http://builds.smoothieware.org/ <-- grab the edge .bin, drop it on your SD card, call it "firmware.bin", unmount and reset. should get some flashing lights, then it should be renamed to firmware.cur or similar after reset'' ''12:11:30 - Triffid_Hunter : cedriko: if M303 still won't work, create an issue at http://github.com/arthurwolf/Smoothie/issues''
J'ai donc mis à jour le firmware. La commande d'autoréglage du PID fonctionne désormais.
