Recovery Mode - Motion Controller

The recovery mode method can be used as follows:

  1. Copy any version “update.bin” firmware file from the firmware folder to the SD card.
  2. Create an empty file named “fcupdate.flg” and copy to the SD card.
  3. Power on the printer. When the printer is powered on, it will force the update.
  4. IMPORTANT: After successfully updating, remove the SD Card and delete the “fcupdate.flg” file. You may also delete the “update.bin” file.
    (If recovering to a different version then follow the steps below)
  5. Export/Save any calibration you have done as the next step will erase/reset everything back to defaults.
  6. Reset EEPROM using “M502” and save EEPROM using “M500”

  7. (Optional) Run PID Autotune

Trouble Recovering?

  • Format microSD card or use another microSD card and try again.
