This is a power supply issue. The manual recommends a separate 12V supply for the spindle and a different 12-24V supply for the logic. Or, add a large capacitor (1000µF) across the DC input.
A CNC control board, also known as a CNC controller or motion controller, is the brain of a CNC machine. It's responsible for interpreting and executing the instructions provided by the CNC program, controlling the movement of the machine's axes, and interacting with various peripherals. The control board receives commands from the CNC program, processes them, and sends signals to the machine's motors, ensuring precise and accurate movements. annoy tools cnc board manual pdf
