Hi all, I’m curious… when I initialize my Shapeoko 4XL, no matter where the router is located, it slowly moves to the far right corner, as I’m facing the machine, and moves to the front right corner just a little left and stops. This is where I would insert a bit to be used for a project. My curiosity is, which one of these locations would be considered the home position? The reason I ask is the router does not stay in the far right corner (as I thought it would) , it moves forward to the front right corner slightly to the left. Thanks in advance for your input… Merry Christmas to all…also, here’s a project I made using HDPE board…

The home position is where the machine initializes. After initialization passes in current versions the router moves to the front right as you said for bit insertion close to the BitSetter.
That front right position is not home. When you create a file in CC you tell the program where you want your X Y and Z zero to be. Many people use the lower left corner of their project for X and Y and some use the center. That is not important where you set the X and Y only that you set it. The Z can be set for top or bottom. Top would on top of the material and bottom would be the surface of the spoilboard. Again it is not important where you set it as long as you set it according to what you set in CC during file creation and saving.
The home position is the rear right corner. That is the machine coordinates and every position set from there is a negative number. When you set your X Y and Z you are setting an offset from the home position and the controller and the CC file work together to send the router to the proper spot to cut. The router coming to the front after initialization is not home just a behavior C3D wrote into the initialization sequence.
There are three positions in play for this discussion:
- machine origin — this is where the machine homes to in the right (X), back, (Y), top (Z) corner
- tool change position — this is where Carbide Motion moves to to facilitate loading a tool
- zero relative to the stock — this is set relative to the machine origin and is set by the user

Excellent description and information. I greatly appreciate it. I kind of figured that was the scenario, but wasn’t sure because the router did not stay in the home position, the right rear position, as I thought it would. Thanks again. I sincerely appreciate it. Merry Christmas.
