In 2020, I built a router table with a manual handle for adjusting the bit height.
It worked, but having to fine-tune the height while watching the scale every time became a hassle, so this time I built an electronically controlled motorized router lift.
The main body is made with 3D-printed parts, and I used linear bearings and a trapezoidal lead screw to achieve smooth vertical movement and high rigidity.
For the control system, I used an ESP32, and the height is adjusted with a stepper motor.
Main features:
・Height adjustment using a stepper motor
・Movement in 1 mm / 0.1 mm / 0.01 mm increments
・LCD display showing the current position and target position
・Homing with a HOME switch
・Zero-point calibration using a brass plate
・Lock function to prevent accidental operation
・Expansion mode for using it as a handheld router
I also performed an actual 5 mm cutting test, and after applying correction, I was able to cut almost exactly to the intended depth.

I hope this video is helpful for anyone interested in DIY, woodworking, 3D printing, and electronics projects.
