3D Printer Z Axis Jamming

edited March 2019 in Motor Control

I've tried everything. Please help. My model is Acrylic Prusa I3 pro B.

Video of the problem:


  • You are just loosing steps as it sounds. Reduce max z spee to 2-3mm/s and make sure steps per mm are set correct. Acceleration for z = 50 as a start. zJerk = 0.3. With that it normally works good if there is no blocking physically or if a motor pin is not connected so only one coil gets powered..
