The machine settings you access through the Machine Inspector is the Firmware. This is stored on the X-Controller and are specific to the machine connected to your PC. Unless you have an X-Carve connected, you will not see the firmware settings available. However, when you connect your machine the settings will persist as they are being read from that X-Controller.
Machine settings, such as what type of machine you have and the work area, are stored in the web-browser. However, these are stored after you have gone through the Machine Setup. If no machine has been setup, you will get the drop down menu to select a machine. This will change Easel’s display of the work area and other features like the Recommended Cut Settings (depending on the bit and material selection) which are specific to our various machines (Carvey, X-Carve 1000mm or X-Carve Pro).
Machine settings can clear in between sessions if your browser settings delete data or cache when closing. You would notice if you have this issue if Easel prompts you to setup the machine everytime you connect the X-Controller to a new computer.
