Hi, Need some help with A350 Snapmaker 2.0. Could someone tell me what I need to change in printing settings in Snapmaker Luban, that would disappear those terrible lines on this print? I will add screenshot of settings I made in a program latter, because as a new member I can add jus one picture. Thank you for help. This is my first printing work. Or maybe Snapmaker 2.0 can not make it? ![IMG_3995](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/9/964f2c42f1ee07fda919329a9da5a667fc570108.jpeg) ---

OK, I see you want to push to the maximum. At this point, you have to start a bit smaller and easier. Try to print it with 0.12 Layer height (or a other multiple of 0.4mm, search for magic number if you are interested) and see if you want to push further. I don’t want suggest you to calibrate your machine after the first print. - It would be good, but normally beginners don’t need to. Anyway your walls are pretty slow, you don’t need to print that slow, 20mm/s would be ok for this details I guess. I would suggest to have a look at this: > [@3d Print Guide\_Walk Through](https://forum.snapmaker.com/t/3d-print-guide-walk-through/5945): > > First of all, congratulations to a great machine! If you have any suggestions to this topic, feel free to send me a PM! You are new to 3d printing?- Be patient. The whole thing is very complex and just little adjustments will make the difference from failed to pretty prints. Start with easy, little things to create (1-3hours i would suggest) . Going to print the first time and then getting a 24h print on, maybe failes. There is a lot to learn, if it didn´t work for a long time, cool off a bi… ---

It looks like you have overextrusion and blobs after retraction. Take a look at your gcode preview. Look where a outer wall is printed after a retraction. This should be where the lines begin. I’m facing a problem like this issue too. First of all calibrate your Extruder E-Steps. Afterwards, calibrate your flow. Then calibrate your temperature and retraction again. If the lines are weaker after that you’re on the right way. ---

Share your gcode with us! I think, there is no calibration needed, at this point. Your previous layers are perfectly, it seems there is a other issue like calibration. Have you even tried with a higher layer?
