I received my printer bundle yesterday and started setting it up today. The setup went smoothly and was completed successfully . I successfully updated the firmware to 5.8.1 over the net work. My UMS5 uses the old motherboard ( i.e early 2020 ).
The problem started when I performed the first test print. I used CURA and sent the print over the network. It was supposed to be a 4 hour print. However after about 3 hours, the printer lights turned off, the printer head stopped moving and cura reported that the print job was only 26% complete.
