Power Fail Recovery
I had 4 printer going today when power failed.
Ender 3 running 220.127.116.11 (2 of these)
Ender 3 running 1.1.6
CR10 running 18.104.22.168
All printing from SD card.
None of the printers would resume after the power fail. All printers showed the proper message on the screen asking if I wanted to resume and all heated up. 2 of them moved to the print and just stayed there doing nothing. The CR10 and the Ender 3 just stayed home after warming up.
Not sure I have ever had to test this so I can't say it's worked in the past or not. I've never updated any firmware, these machines are running what they shipped with.
