Any way to resume print after losing connection? I just lost 36 hours of printing.
I've had my Raspberry Pi / Repetier Server Pro (.90.7) setup fail on me a few times in the month and a half that I've been using it, and each time it's caused a catastrophic failure of my running prints. How on earth can I mitigate this? The server has, on all three occasions, crashed during the upload of a gcode file to one of the printers. It makes me afraid to do anything with any printer on a server that is printing. Are there any logs that I can provide, or more detailed information? I'd love to never have this happen again, as it's a significant opportunity cost for me.

Your symptoms let me think your power supply is not stable. After a while of usage login via ssh and enter
dmesg
and see if it contains linux warnings about under voltage. This can lead to disconnects and in hard cases will crash linux. This happen often under bigger load like when you upload a file and it gets analysed increasing cpu usage.
Did z axis move between restart or on reconnect through server? The rescue system requires that z axis holds position or it will loose it. That does not include the z move that gets reported to server from firmware rescue system assuming this happened as you said extruder did go to the side.
Park position Z raise [mm]
it will raise that amount and that is ok. Any additional rise maybe because it drops a bit after reset would not be ok.
You can try to set this raise to 0 for testing. Then you know any raise you get is causing the problem. For testing I just use a simple fast object and unplug usb at some point.
