Hi again, everybody!
I built a Graber reprap 3D printer and it was working very well.
But in a week or two, it started to show this error message in the middle of the printing process.
And yesterday, it stops printing because of the same message as soon as the fan starts in the second layer.
I have investigated the direction of the air flux, and it is going straight to the nozzle, not to the block.
Also, I preheated the nozzle to 210ºC, with the fan in 100%, waited a lot, and the temperature was ok.
It seems very clear that the problem is caused by the fan, but I cannot see how to fix it.
Does anybody have an idea of how to fix this?
Thanks a lot!
Let nothing disturb you,
Let nothing frighten you,
All things will pass away.
God never changes!
Patience achieves averything.
Whoever has God lacks nothing!
God alone suffices! Amen.
