so, I'm glad now, that I was babysitting the printer...
suddenly (i assume) there was a Z=0-movement - I've hit the power switch a millisecond before my glass plate was shredded.
I've printed this model maybe 50 times (this specific gcode maybe 10 times), with no issues other than the Heater Error (which is why I changed to TinkerGnome's Firmware for the PID-Settings [alternative Fan-Shrouds] )
regarding the ribbon cable placement see this photo
I can NOT recommend to seperate these 2 ribbon-cables to fix the issue of unpredictable movements on TinkerGnome's Firmware V16.08.02
Maybe @tinkergnome could set up an experimental branch of his FW with the old SD-Library for testing, because this was the suspicious part in other threads than this one?

I've cut the shrinking tube and the mesh cover (carefully with scissors), seperated the cables so that they are running in parallel (not on top of each other; 'bout 2cm apart from each other) and fixated them on the bottom plate with gaffa.
printer is running, so i can not take a photo at the moment.
...and to the bad news unfortunately:
I'm in an 17hour print, and 5 minutes ago I had a single random travel to X0 again (print continues, but surface isn't perfect anymore and again I lost trust and I'm babysitting the rest of the print-time)
:(

Alright, thanks for the info. I checked the cable, wanted to know if there was a loose connection, but it is fine.
I have a 5h print going on, so far it is stable.
