I have now moved back to nGen (first time on hybrid) a wonderful material, which breaks easily I know. I am printing test figures for calibration in the centre and I notice some weird asymmetric z banding. It is present left of the centre but not right ... My feeling is that it is related to retraction as I can always see a tiny blob on the left side followed by something which could be banding which disappears towards the end on the right side of the print. I never saw this so I am doubting. Any other possible explanation for Z banding on one side and not the other? I will try with a negative "extra retraction distance" to see if the problem is over extrusion instead of banding. Thanks for any other suggestions I could try to get to a perfect print.
