selfest possibly blew the fuse
After my initial assembly of a new MK2S kit I did a firmware update (Used 1_75mm_MK2-RAMPo13a-E3Dv6full.hex) which worked according to the firmware-update tool. Then I went ahead and tried the selftest as per the pre-flight video on YouTube.
The first two stages went ok (both fans worked). However, when the printer started the test on the hotend it lost all power and cannot seem to be powered on again (I tried switching off the power-supply and unplugging it too before trying again).
I think it may have blown a fuse but I would like to make sure first if I am right, which fuse I would have to change if applicable and if I can do anything to prevent that from happening again.
Thanks in advance for any help!
Is this a good question?
