Ultimaker UM2+ freezing/locking up

[Judogido 0]

Just purchased a brand new UM2+. Arrived Tuesday and I am setting it up today.

 

I unpacked, removed the cable tie, switched on the unit and began to run through the "first use" guided sequence. As I scrolled the wheel to raise the bed for the first 1mm to nozzle adjustment, the firmware froze and became unresponsive. Button press did not work and scrolling did not work. So I restarted the unit and all went OK.

 

Next I had issues with printing directly via USB connection from Cura 3.4.0. Therefore I updated the firmware to _3.3.0 and Cura to 3.4.1.

 

While scrolling through the menu it again froze and needed a restart. I have since reset the unit to factory settings and had to run through the setup sequence again. So far no locking up, however I am concerned that it has now frozen twice.

 

Is this just a normal thing for the UM2+ machines?
