I have a question in strange English from Japan. Sorry.　I am a recent newbie to 3D printing, using an ANKERMAKE M5. I have tried all the settings in cura to show/hide seams and smart seams, but I can't help but get the bumps in the circles. It appears even if I change the filament temperature setting or print speed. Are there any other settings I should try to change? I would appreciate it if you could let me know as soon as possible. Thank you.
