      Can duet save to sd like Marlin?
      Power-loss Recovery feature. When this feature is enabled, the state of the current print job (SD card only) will be saved to a file on the SD card. If the machine crashes or a power outage occurs, the firmware will present an option to Resume the interrupted print job.

      This feature operates without a power-loss detection circuit by writing to the recovery file periodically (e.g., once per layer), or if a POWER_LOSS_PIN is configured then it will write the recovery info only when a power-loss is detected. The latter option is preferred, since constant writing to the SD card can shorten its life, and the print will be resumed where it was interrupted rather than repeating the last layer. (Future implementations may allow use of the EEPROM or the on-board SD card.)

        Duet WiFi and later have power loss detection built in, so they don't need to keep writing to the SD card. https://duet3d.dozuki.com/Wiki/Setting_up_to_resume_a_print_after_a_power_failure

          How does this work when running Duet Software Framework on a Raspberry Pi? Does it talk back to the PI and write to the SD on the PI?

              So there is no power recovery with DuetPi at this time correct?
