Speed to avoid shifting? Temperature according to speed?

    Hello,

    I have a question regarding "real" accuracy per axis.
    Why? Because at my point of view all my printed parts have shifting on X/Y (0.1mm at least).
    I already checked all gears and belts!
    Nozzle is 0.3mm stainless steel.

    When print speed is low does the temperature have to be reduced?

    The print speed does not affect print temperature much.
    I am not seeing the 'shift's in that picture. You might want to provide better pictures to demonstrate your question.


    I *might* be seeing a little ribbing, but that could be over-extrusion. You could try calibrating the extruder.

    (Mine does not do that so something is off. You could slow down acceleration and jerk settings as well.)

    From that picture the layers look normal the layers will have a rough feel to them at least from my experience from the C2. Try printing a small cylinder shape and about 70-80 mm high and see if the shape stays consistent the entire way.

    I disagree.

    Then maybe its just mine but all my prints from day one had a slight rough feel to them they were never smooth

    With higher layer heights you can sometimes feel the layers, but normally that would be a sign of something slightly off.
    Slowing things down is always a good test since if changing the print speeds DOES have a positive effect then you know something needs a tweak (unless you were printing too fast to start with).
