R1D1 > extruder error

The printer says the extruder (SA057363) has short-circuited. The extruder has not been repaired before, which makes it unlikely that something happened while it was being opened up and tampered with. When the extruder was replaced, R1D1 still said there was an error, but this time for a different reason “tool fan open”. The first extruder is now next to, but not inside, the ‘Jammed’ box as there was no designated place for extruders with other problems.
