Yup, had the same issue. I was very confused at first, as to why my print would not smooth with acetone vapors. Then tried making ABS slurry for build plate adhesion, and noted that the UM ABS would not dissolve at all.. Now I am stuck with 10(!) rolls of so-called ABS from Ultimaker, that I opted for with the sole reasoning that it can be post-processed. This stuff does not even sand like regular ABS. Quite disappointing.

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.
