First look at your part in layer view to be sure these crazy movements aren't part of the gcode.
But that is unlikely.
More likely your um2 is getting errors when reading the SD card.
1) try a different sd card. Buy one if you don't have any spares.
2) try cleaning the sd card slot. I had to take my um2 apart and clean that slot very well. I found a tiny hair in there (eyelash maybe) and after cleaning the random motions went away.
You might be able to get away with just compressed air and not disassembling but that hair was very stubborn for me.
Before you disassemble anything note that if you slide the bed up and look inside there is a semi clear part with a hole in it - you can see that if you put a small screwdriver in that hole and push it pushes the main control knob off. That was the only tricky step for me. once you expose the nut you can remove the nut and remove the screws that hold the cover on and remove the screws holding that small pcb down.

We don't often release an alpha version of Ultimaker Cura... So what's different this time? This Alpha contains such a huge slicing engine overhaul that we really need your help!
We wish to celebrate and honor the innovators that push forward the field, technology and world. We opted to not present it as a competition or ranked list. Every innovator has earned his spot on that list in their own way. We also look at the 3D printing industry as a whole and not limit the list to those only using Ultimaker.
