Common fault & Solution about CNC Router(1)

1. One axis or thre axises were all not moving, also sometimes not perfect-moving.

(1) Controller card was loose; (2) The equivalent axis driver was wrong; (3) The equivalent axis stepper motor was wrong; (4) The equivalent coupler was breakaged/loosen; (5) The equivalent lead screw was breakaged/loosen; (6) The equivalent slider was wrong; (7) Driver’s MICRO/ELECTRICITY was different as in the software.

2. Z axis out of control

(1) Controller card was loose/wrong; (2) Electrostatic interference; (3) Z axis’s Motor line fault; (4) Files route was wrong; (5) Transducer interference; (6) The computer was wrong; (7) Misoperation.

3. Mistake was bring

CNC Router machine’s routine attention

1.  If the cnc router machine working exceed 1o hours per day, must guarantee the cooling water under cleaning & the water pump under well-operating.
In order to prevent the water temperature was high enough, remember to change cooled water at regular time.

2. There will be certain dust on Working table & transmission system after long-term operating; please remember to clean it.
Meantime please also oil pumping on XYZ axis at regular time.

3. If the cnc router machine was not use long-term, please also oil pumping & guarantee XYZ axis moving; just confirm the flexible about the transmission system.

4. Please clean the electrical cabinet at regular time; check the all wires & screws under perfect situation. Just guarantee the safety about electic circuit.

5. Don’t forget to chek the all screws on the machine fasten enough.
