I'm been running Octoprint for a couple of months now, And since one o two days a SD Init Fail begin to appears on My Screen.
When I checked out I realized this happened just without SD Card inserted, when I have one card on the slots it's ok. So I unplugged the Octoprint to verify if the problem was in the printer, but When I unplugged the octoprint from the printer and restart it. No more error.
The only thing that I did recently updated de PSU Control Plugin. but I'm sure if that is responsible for my problem.
Please Your help
