Cartesian setup, need help tuning



  • I so built this printer on CR10 frame. I have heavy moving plate (410x420x8) driven by NEMA23 motor. Extruder direct drive driven by large NEMA17 on the X.
    15mm linear rails on Y with 4 bearing blocks, 12mm rails on Z and 22mm rail on X. Extruder and heatblock are e3d titan aero (with their 25mm motor which might be a cause). PT100 and Modulated IR.
    Belts are tight.
    Here are my results and i dont know if its extruder motor causing it or something else:
    Material 1.75 PETG

    Here is my config.g:

    Inconsistent layer lines is my headache. I printed lots of benchies and cubes
    Any help appreciated

    Extruder tuning is done.
