Ultimaker 2 extended

It was working fine. Yesterday I changed nozzle to 0.25. now when I try to change the material, it reboots .

Any solution?

very strange. Maybe it reboots on temperature to nozzle? Try turning on only nozzle heat - see if it reboots for that also.

Do you have the right power supply? Possibly using um2go supply on um2ext?

Normally reboot happens when you try to heat the heatbed but not the head (when you have the wrong power supply).
