Pessure Advance

T o tune Pressure Advance, I printed a square tower with 0.3 mm layer height and a 0.6 mm nozzle in PLA + . The best results were with: pressure_advance: 0.160500
pressure_advance_smooth_time: 0.040000 However, I’m still getting ripples or waves at the beginning of each straight line in all axes. What other test would you recommend to help eliminate this issue?
