As soon as I hit Run the router raises about 3/4 of an inch then proceeds with the tool path well above the stock. I am very new to Cam, I have been using Fusion for a few years for hobby 3d printing.
I have a shapeoko standard.
I am using Fusion360 to model and create tool paths and GCode.
I am pretty sure my problem is my setup in Fusion but I can’t find where this behavior is coming from.
Carbide Create works great, not problems. Some of my Fusion projects work fine.
Any help is appreciated.
Should my origin be on the stock top? Or are you saying the two need to be the same.
If My model origin is on the bottom and I use model origin in the Heights settings should that do the trick?
If the stock origin is on the bottom will my top height be a positive or a negative?

To keep it really simple, think of High School Geometry class. G_code stands for geometry code. The Shapeoko and most CNC’s work in the positive quadrant of the grid. Right is X+, Forward is Y+, and up is Z+. Everytime you see a “G1” in the code there is a linear(straight line) movement to a coordinate. “G2” there is a clockwise circular movement, and “G3” there is a counter clockwise movement.
This is enough info for you to see which way the machine is moving.
All of your Z movements are positive, so the machine was going up from where you set your 0,0,0
Hope this helps a little. But follow Will’s links.
Your model origin doesn’t matter unless you want it to. The work origin is set in the setup, not the toolpaths.
If you set it at the bottom of your stock in Fusion, you should be zeroing your Z on the wasteboard.
