Vertical print lines
Hi All,
I recently purchased and built my mk2s (I love it and it's been running almost non-stop for the last month now), so I'm still learning a lot but I think understand the basics now.
I usually get pretty good clean prints with PLA, but I just printed a cylinder (roller for dry box) and there is a vertical line that goes up one side, and seems to move slightly at different layers.
Any idea what might cause this (and the other bumps)?
Re: Vertical print lines
This is the place where the printer leaves one layer and goes to the next.
You have some control over this. For Slic3r, see the setting:
Print Settings -> Layers and Parameters -> Advanced -> Seam position. Set it to "Random" to make this seam less obvious.

Re: Vertical print lines
Thanks for the info. I'm using S3D and found the setting.
Is there any other way to minimize the amount of blob it leaves on the seam? I'm trying to get a precision cylinder made (as best as possible anyway), and it just seems like it's a lot.
Re: Vertical print lines
The retraction setting - distance and speed - seem to affect it. Also if you are over extruding that makes it worse. Have you calibrated your extruder?

Re: Vertical print lines
Actually, I went back and did some extrusion calibration, adjusted the tightness of the u-bolts on the Y carriage, and changed several of my settings back to original profile from Prusa (S3D), and it seams (lol) better. Definitely not perfect, but better - and apparently there is no way to get it to completely go away with FDM printing anyway.
