4th axis rotary setup

Post by djreiswig »

I tried this question over on PlasmaSpider, without much success.

I guess technically it's kind of a sheetcam question, so let's have a go over here.

Setting up a rotary on my table. I have a 4 jaw chuck. With my zero switch, am I correct that it should home as if the y axis was moving over the pipe in the same direction as it homes on a flat sheet? For example, if I'm facing the torch and if I home the y and it goes left then the top of the tube should rotate to the right.
Also, for square tube it should home with a flat face up, correct?

I know for round tube the y home should be the center of the tube. Is this the same for square or does it need to home to a different place?
