This project controls high-power motion hardware. Software limits are not a substitute for mechanical end stops, a hardware emergency stop, drive-level limits, correctly wired brakes, and a safe operating area.

• Test without a driver in the rig and at the lowest practical speed.
• Verify axis direction and homing one axis at a time.
• Keep clear of the mechanism whenever servo power is available.
• Ensure every StepperOnline A6 750 W servo drive can be disabled independently of this software.
• Do not use the software if the Modbus wiring, grounding, braking, or emergency stop chain has not been validated by a qualified person.
