The Redline CNC Controller is an all new, built from the ground up, controller that Onefinity designed in conjunction with Redline to create a modern CNC controller with advanced features, expandability, and ease of use at it's core.

Advanced Redline CNC Controller — The All New Redline CNC Controller

Redline CNC has created some of the best CNC spindles on the market with their all metal VFDs, 1.5kw and 2.2kw power options, 80mm and 65mm size options, and safety certification, leading the way in spindle quality in the hobby CNC market.

By partnering with Redline, we’ve combined our five years of experience and the insight gained from tens of thousands of machines in the field to deliver exactly what our customers have been asking for: the most-requested features, simplified workflows, an intuitive layout and GUI, and innovations inspired by real-world support feedback.

This collaboration has resulted in a controller designed to be loved by our users and to redefine the standard for modern CNC machines—just as we did in 2020 with the introduction of the Onefinity CNC, making ball screws standard; again in 2023 with the Elite Series, which brought closed-loop steppers to the hobby CNC market; and now, once more, with the release of the advanced Redline CNC Controller.

Check out the first look at the advanced Redline CNC Controller from our AWFS 2025 unvailing:
