Hi everyone. Can I please ask for advice? I just bought Creality k1 and no matter the settings I've tried I keep having low quality outer walls due to ghosting or VFA. I think it's most probably ghosting due to too much vibration. I tried hard top surface placing the printer. Loosened the belts to 110Hz at 150cm length. nothing works. there is no difference at all. Can you please share your thoughts?
