It depends on how you set it up in your CAM. In Fusion 360 you can set the origin in the center or at any corner of the workpiece. The most common place to set the zero is either in the center of the workpiece or the bottom left corner. Some also set to the top left though when working on a vise. The important thing is that you zero to the work piece on the machine the same way that you have your origin established in Fusion 360.

Alright so Im watching the tutorial you have on youtube and have fusion 360 here and I have my axis's all correct and I can run a simulation that goes through my shape correctly how I want it to. But im a bit confused, How does fusion know where my spindle is mounted on my mount? I have yet to choose a spot but I think im going to bottom out my z axis and put the spindle in so its as low as it can go without touching the starboard. But how would fusion knows this and how far to plunge in? Does it just decide to go down from my zero point im using? (but again a bit confused where I set how far the z axis needs to move to get all the way into the foam im gonna practice on even if my tool size is put in correctly)

How does fusion know where my spindle is mounted on my mount? It doesn't. Or at least I'm not aware of any settings for location of you machine bed or spoilboard. I set up my carve king like this initially. Thinking if I did screw up, the CK would run out of travel before cutting into the super sweet Starboard. But bits come in many different lengths and sizes and how far each one sticks out depends on how far you insert it. But I use a free program called NC corrector( www.nc-corrector.inf.ua/index_EN.htm ) to check my CAM programs(post processed gcode) to make sure they don't cut too deep or make any unwanted movements. The Fusion 360 simulate option is great, but does not simulate the actual gcode that you post processed. That's why I use NC Corrector to check the actual gcode file that Fusion 360 or other programs I use spit out. My CK has always done exactly what the gcode tells it to do. Cause as far as I understand, if you gcode and stepper voltages are correct, the only things you have to worry about is bit deflection and losing steps(which in my experience, the CK does not do  ). As far as I know, some folks like to set their Z plane origin on the material surface and some like to set the origin on the bed/ bottom of the material. You can set it to either in fusion. Then you set how far up or down from the Z origin you wish to cut in the programs you create. I like to set the origin to the top face of the stock material. Then set how far below the material surface to cut in whichever cutting operation I select in Fusion. This can be a little confusing till you get in their and get your feet wet, but keep the questions coming. We are happy to help and look forward to seeing what you machine |

Alright , ran some code . only weird thing I see is I start from my zero location right, when the cut is done it goes back to my zero on my x and y axis but the z axis is like 15mm higher than my zero is set to.. any ideas?

Also, any ideas why fusion skips these areas and the smaller holes? imgur.com/a/IeyXuc8I can see maybe the smaller holes since there 2mm holes and its a 2mm end mill but a bit lost on the 4 rounded areas |

It probably was just commanded to end up there at the end of the code: IE: G0 X0 Y0 Z15
That is odd on Fusion skipping the rounded areas. Are you selecting the sketch or the body in your CAM? MY suggestion would be to make sure that sketches are turned off when you enter the CAM workspace. I'm guessing it's seeing a broken sketch line and selecting that as the path.

Yeah, I was thinking the rounded edges it is skipping were not selected. Curious what material it is and how thick, cause I only see one pass. You may have to select the drill op to do the 2mm holes with a 2mm bit. |

Just messing with some practice runs on foam but eventually 3mm carbon fiber, very low feed speeds.
