this should be rather easy. You already have CNC experience.

You open your [favorite CAD/CAM program](https://forum.onefinitycnc.com/t/what-cad-cam-software-can-be-used-to-make-gcode-files-for-the-onefinity-cnc/10253), create a 3D model of whatever you want to mill, select the [Onefinity Post processor](https://forum.onefinitycnc.com/t/what-is-a-post-processor-what-does-it-do-and-why-do-i-need-one-specificly-for-my-onefinity/8709), export the toolpath as g-code to a USB stick (needs to be formatted with FAT32, NTFS or ext4 – support for modern exFAT is not installed¹ on the Onefinity Controller ☹), insert the USB stick into the Onefinity Controller, click on the “Upload a new G-code program” icon, select the file, switch the router on, and click on the “Play” icon.

If you want to watch videos, you know where the [OnefinityCNC youtube channel](https://www.youtube.com/@OnefinityCNC) is.

There you can

- [Learn how to load a g-code program on the Onefinity](https://www.youtube.com/watch?v=f7mWnIIRgoA&list=PLlCbxVoOUWYVO32LhRoaSyQZnD1LgNl5p&index=4)
- [Learn how to use the Touch Probe](https://www.youtube.com/watch?v=p84CB9iMl6Q&list=PLlCbxVoOUWYUXrMYLUP5_GdxAxrRtRtF3)
- [Watch all the other “Support” videos](https://www.youtube.com/watch?v=LewgFJ76xcw&list=PLlCbxVoOUWYVsInAIXHKKvWGEqJqoELFD).

1. – would become available via [fuse](https://en.wikipedia.org/wiki/ExFAT#Adoption) on the older Raspberry Pi OS version found on Onefinity controller by doing ‘apt-get install fuse exfat-fuse exfat-utils’
