Looking at the knitting on the Cadyo I just understood the history of tension. The tension we choose is the spacing between the rows which means that the stitches are more or less tight. Even if you adjust the tension that unfortunately your yarn gets stuck just a little, (rolls badly, hangs a paw, passes a knot) the row in progress will be tighter. Hence the importance of having wool well rolled up and well cleared so that the thread comes out well. I had some little trouble on some knitwear, the wool was just pulling a little, well believe me, on the Caydo it seems! Here is an example. It's not major, I'll have to stretch the knit and block it to improve it! I have a regulator of tension on my Addi and my Sentro, there are less sensible but the tension isAdjustable in quarter of de tour.
