Horizontal and diagonal lines on print - A10M

[dionlima]

Hello, I have spending months trying to calibrate my A10M but fine tuning seems to be impossible, now the big problem is the vertical surfaces with horizontal and diagonal lines, I have tried: Change temperature, fan speed, extrusion multiplier, layer height and etc..
This problem is only visible when printing large parts, when I print a 20mm cube everything is fine or the cube is not big enough to see any issue.
Can anyone help-me to have a clue of what I have to do to improve the surface quality? Photos attached

Thanks for helping, now at least I have a clue, by the way, thanks for your work with 2.0 version.

Did you tried lowering the jerk values and printing speed ?

I have no experience with such large parts so I can't say for sure, but it may worth a try. Before I lowered jerk to 8 (default 20), all my printing were ruined because of bad y shifting. For a large part I would even lower it to 0 with a quite low speed if I would want a almost perfect surface.

I'm going to try, Thanks!!
