I am testing the acceleration and I have found a problem.
When I rotate the part by 180°, the printing is almost good.
I will try to explain, when the head travels away from the motor, I have minimal ghosting, but when the head comes towards the motor, the ghosting appears.
I have the same situation with X and Y axes.
I checked the motor, the belt, ... all seem correct but I am sure I have a problem.
Did you have the same problem ?
The picture represents the same part printed twice with a 180° rotation to show how the aberration appears in only one direction.
