Resuming a failed print on UM3

[TacMonkey 0]

I have just run a huge 24h print om my Ultimaker 3. Sadly it failed at late point in the middle of the night, filament got stuck and ground in the extruder, with the printer continuing printing in mid-air.

On my previous, simpler printers, I have been able to fool it to resume by editing G-code to start at a meased height. The UM3, however, is so full of bells and whistles, like the auto-leveling etc, and I cannot come up with a smooth way of doing this. The print head will crash into the huge print on the bed, and its all together a complicated task.

Any ideas how this could be done?

Perhaps a future feature idea here, to create such a function in Cura.. skipping the calibration, just homing in and continuing the print.

Hello Tac,

I'm having the same problem, have you discovered any way to solve that? 
I can't find a way to disable the initial calibration too

the easiest way to deal with this is to print the missing part by detecting where it failed, then sink the model in Cura beneath the bed and glue the parts together.

Even if you could manage it to resume the print, it will be a visible seam, which also happens if you pause and resume a print.

Thank you @peggyb for your attention, I used to do this in the past when printing with Fortus400. After reading some topics I've discovered how to turn off the auto leveling. But the print head is still hitting the piece, for some reason, the height that I've chosen to cut in the Gcode is wrong, for now, I don't have much time to run some tests but I'll give a try another day.
