Power outage

[AlainSMT 0]

Hi, I have lost 15 hours work in the middle of a 25 hours job. 

We had a sudden power glitch for a few mili-seconds causing the printer to go through a complete reboot.

I could not resume the job. Other than adding a UPS is thee a way to recover from a power outage?

If I add a UPS and I manually pause or stop the job, then turn off the unit, can I resume later on when the power comes back?

This is with an S5?  you can do it but it involves editing gcode files.  Well even then you can't do it because the active leveling can't be disabled on the S5 and that would ruin the existing print.   Unfortunately the S5 printer firmware does not have that capability.  I'd still get the UPS and at least that will cover brief power glitches. 

 

The UM2 and UM2+ can do this if you have the tinkerMarlin firmware installed but not the newer printers (S3, S5, UM2+C).

 

For me - 15 hours into a 25 hour print would be worth it.  I'd immediately heat the bed back up to temperature (otherwise there is a large risk the part might pop off the bed).  Then I'd figure out exactly which layer failed and then edit the gcode by hand to start at that layer.  I did this once for a failed UM2 print job that was more than 10 hours (resume failed print).

 

But again - you you can't do that on an S5 because of the active leveling.
