#Help Center - So I've had my A1 for a month or so and only made a few prints which I think have been going pretty well. However I'm not completely pleased with my latest print of the A1 Toolbox by martonlengyel.design. There are some outliers that I have also noticed on other prints, i.e. "holes" between wall loops (see picture of bambu lab logo) and also very noticeable layer lines that are also incoherent (see picture of the sides of the box). In case of the layers the layer height was 0.3 mm so maybe I should've just gone with 0.18 or something like that? Regarding the holes - I did an automatic calibration, but it didn't help. Not on the logo anyway.. Can this be related to me using a 0.6 mm nozzle and the model being made with a 0.4 mm nozzle in mind? I just can't see how that should be an issue for "painting" a flat surface... Thank you in advance for any and all feedback!
