Seems like you reached the end of your x-axis but your drawing is bigger. Other words: It seems like your drawing is bigger than your machine can make…

Thank you for your feedback but I have many centimeters before the end of X axis

@LightBurn hello, I’m sorry to disturb you, But have you got an idea ?
Thank you

Are all screws tight? With no resistance it’s working well in that case, but when it reaches a point that has more resistance it will slip…So the ax keeps moving, but doesn’t take the construction with it.

Hello Is not a mechnical problem, the next letter was not problem and is position was good

Okee… Good luck then

That looks like either the stepper motor stalled (somewhat unlikely) or a communication issue of some kind. How are you connected to the machine?
