the duration of printing a part is 9.00 hours. after 5 hours i paused the printing since the filament was running low.
gently i replaced the old filament with the new one and also turned on the led lamp and resume the printing. immediately i saw that something was wrong- it was printing in mid air and the X axis was jamed. sadly i had to stop the printing.
than i auto leveled with the led lamp still turned on and i notice that something is wrong: according to the screen the printing head should have been on the right side of the plate but in reality it was in the middle, and it didn't manage to return home and gave a warning sign 202 (picture) .
than i turned the printer off and on, auto leveled it and started printing again.
question- why the led lamp had caused the printer "a stroke" ?
