I recently designed and machined an upgraded linear tool rack which now holds 24 ISO20 toolholders.

In this video I give a summary of the steps I used to set it up and configure it with my Masso G3 controller. It is not meant to provide a detailed howto, but I do show all the main steps including: leveling the rack, determining and recording the tool slot locations, and using a tool setter, and the auto tool zero function, to measure and record the tool length offsets in the tool table.

Note that I purposely am using very conservative feed rates during the setup and configuration stage all these can be adjusted to suite your own needs and goals.

The Masso G3 controller, Jianken ATC spindle, and EMG Sprite10 tool setter were upgrades I added to my Onefinity X50 Woodworker CNC.

Other videos on my YouTube channel show some of my CNC build and modifications, including one showing the design and machining of this new tool rack.
