Folger Prusa i3 Kit doesn't print.

My folgertech prusa saga continues. I got half of a print off, after which I cancelled it and my fan in the power supply broke. Now I'm getting the sd init fail and unknown command errors. my firmware is marlin V1. I have no sd card on the ramps board so IDK why i'm getting this error, especially when it has worked in the past.

Everything mechanically works fine - moves, heats, extrudes, homes, etc. Please assist!

SD Init fail simply means that the feature is enabled in Marlin, and it can't find a card. More of an annoyance error, if anything . . . I have gotten it for 3 months or so, no impact at all.

Dammnit. So any idea why it has stopped working?

Did the fan in the supply fail, or did the supply fail and the fan is just a symptom? Sounds like it could be a power problem . . . have you metered the supply?

And can we see the actual errors? You haven't really given us much to run with . . . but a power problem may keep the bed or extruder from coming to temp, and the print job will wait until it does . . . . possibly forever . . .

The fan in the power supply failed (broke off the mount).

I haven't metered it, but I just don't understand how literally everything on a printer can work (all axis move, it extrudes, fan on, etc) but it just won't actually print anything. No errors in the gcode either that I see other than those and "unknown error".
