Revision to Setting up to resume a print after a power failure

David Crocker

 
'''These instructions relate to RepRapFirmware 1.20.''' The auto-save facility was first introduced in version 1.19, however improvements in 1.20 necessitated changes to the configuration mechanism.
 
== Overview ==
 
RepRapFirmware can be configured to allow you to resume a print after loss of power. This can be used in two ways:
 
* To handle unplanned power outages
* You can pause the print, turn off the heaters, wait for the hot end to cool, and turn the printer off (e.g. because you are no longer available to attend it).
 
== Limitations ==
 
* YouIf you want to handle unplanned power outages, you should use 24V power, not 12V. This makes it much more likely that there will be sufficient power left to lift the print head and save the resume information when power failure is detected.

* You must be able to re-home the printer (possibly using a different homing sequence from normal) with a print on the bed.
* If the print becomes detached from the bed while the power is off due to loss of bed heat, you won't be able to resume the print.
