Mill with CutControl

Last updated: August 30, 2022


CutControl is a proprietary controller software made by Langmuir Systems to operate the MR-1 CNC Mill. The software was designed with several key features specific to milling while offering an easy-to-use interface.

CutControl software is used to connect your computer's USB port to the MR-1 CNC Electronics unit for controlling the machine and for running milling programs. The below User Guide explains the features of CutControl and how to setup and configure this software for use with your MR-1. We highly recommend reading and watching this User Guide in its entirety before operating your machine and software.

We are continually updating this guide with more information as documentation becomes available.
