Setting the cutter properly is probably the most important for flawless results, I agree you can compare cuts with Rubi on biscuits but just wait till it’s full on porcelain the Sigma goes into overdriveSetting the height makes all the difference. Previously I was getting quite a rough edge on my biscuit. Now it’s set up properly, it cuts flawlessly. Identical to the Rubi.
Also had a proper look at lining up the tile with a pencil mark. Yes it’s going to take a bit of getting used to. One way I have found is to mark the pencil line down the biscuit so it lines up with the breaking bar.
