Hello!


Thank you for your response! I thought I will receive any notification to my email that someone has responded, it turns out I hadn't... .


Of course, on the picture I meant the nut, not the screw - sorry. Distance between the bands are 4,00 mm (0,158') and the leadscrew is trapezoidal screw T8 x 8. So, It looks like half of the lead.
But I have replaced the screw (integrated with nema stepper motor) as well as the nut from the picture and the issue is still there.
