CNC Router Trouble Shooting
Machine will not start.
1. Check that the start switch is being pressed full in.
2. Check that the red stop switch is fully out.
3. Check that the electrical power cords are not loose and are plugged into the power outlet.
4. Check that the electrical supply is on [reset the breaker].
5. With the power disconnected from the machine, check the wiring to your installation.
Check that the rubber insulation is stripped enough and is not causing a bad connection.
Check that all the screws are tight.
The machine will not stop.
This is a very rare occurrence as the machine is designed to be fail-safe. If it should
occur and you cannot fix the fault, seek professional assistance. The machine must be
disconnected from the power and not run again until the fault has been rectified.
1. Internal breaker faulty. Replace the breaker.
Motor tries to start but will not turn.
1. With the power disconnected from the machine, try to turn the spindle by hand. If the
spindle will not turn, check the reason for the jamming.
2. Motor faulty. Replace the motor.
3. Spindle run without coolant. Replace the motor.
Motor overheats.
The motor is designed to run hot, but should it overheat it has an internal thermal overload
protector that will shut it down until the motor has cooled and then it will reset automatically. If
the motor overheats, wait until it has cooled and restart. If the motor shuts down consistently
check for the reason. Typical reasons are dull cutting tools, no water in the coolant tank,
blockage in the coolant pipe and excessive ambient temperature.
Squeaking noise.
1. Check the bearings.
Spindle slows down during a cut.
1. Dull cutting tools. Replace the tool or have it re-sharpened.
2. Feeding the wood too fast. Slow down the feed rate.
Machine vibrates.
1. Machine not level on the floor. Re-level the machine ensuring that it has no movement.
