Hey Scott, as the Onefinity Controller is a stand-alone CNC Controller, the user interface on the display is mainly used to **open the g-code file** you want to mill, after you connected a USB drive with the file on it. You will also have to press “Play”/“Pause”/“Stop” to control g-code program run and press “Continue” on the popup windows when workpiece XYZ probing with the touch probe or on manual bit length probing on tool changes. But you can **get by completely without connecting a monitor directly to the Onefinity controller** and **skip buying** the touch monitor, since the User Interface can be controlled completely from any **remote computer**. This even has the advantage that you can see the [CAMotics.org](http://CAMotics.org) 3D toolpath simulation that is not available on a monitor directly connected to the Onefinity controller, as the internal Raspberry Pi 3 has no 3D graphics acceleration package installed. In the case you use a remote computer, you need no USB drive since you can simply click the open file button and you will be able to select a file from your computer. ![Flattening_File](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/5/4/54649f2849eb7c62768c93b8061174d46e432213.png) Image: The 3D toolpath simulation when viewed on a remote computer. --- _[View the full topic](https://forum.onefinitycnc.com/t/i-need-a-shopping-list-for-ordering-my-first-cnc/19705)._
