The latest Marlin Firmware for the Vertex is the Version 1.4
The full procedure to update the Marlin Firmware is available here
It seems that the upload with the latest versions of the Arduino software isn't giving correct results and leaves you with a corrupted firmware. Use Arduino 1.0.6 instead (available here)
M:1.0 V:1.0 HEADS:2
- M:1.0: The version of the Marlin firmware (1.0).
- V:1.0: The version of the VERTEX modifications to the Marlin firmware (1.0).
- HEADS:2: This indicates for how many heads the firmware is configured (1 or 2).
You can download the Single and Dual extruder versions here :
DO NOT FORGET TO RELOAD THE EEPROM SETTINGS AFTER THE UPGRADE!
- When you have uploaded a newer version of the firmware you must reload the EEPROM settings. This will update the stored values on the printer as these are not updated via the Arduino upload process. Go to the SETTINGS menu, then scroll down until you see RESTORE FAILSAFE, access this menu and the firmware will load the new values into the EEPROM, next choose the STORE MEMORY menu (also in the SETTINGS menu) to store the new values.
