Common fault and solution about CNC Router(2)

Posted on by

4. Different engraving depth
Solution: (1) Control card was loose; (2) Stepper motor was wrong; (3) Drive was wrong; (4) Z axis lines was wrong; (5) Spindle motor was wrong; (6) Transducer was disturb; (7) Electrostatic interference; (8) Computer virus.

5. Engraving not normal
Solution: (1)Control card was loose; (2)Transducer was disturb; (3)Files route was wrong; (4)Electrostatic interfernce; (5)Software setting not OK; (6)Drive was wrong; (7)Data cable was wrong; (8)Computer virus

6. Milling not flat
Solution: (1)Spindle was vertical to working table; (2)Engraving tools problem; (3) Control card was wrong; (4)Z axis Drive was wrong.

7. Spindle stopped suddenly
Solution: (1)Inner lines short circuit in the Spindle; (2)Bucking current; (3)Transder parameters was wrong; (4)Control card was wrong; (5) Spindle cable and Data cable under short circuit.

8. Spindle moving owning noise
Solution: (1)Transducer parameters was wrong; (2)Spindle was stopped; (3)The spindle was wrong.

9. The machine can’t back to original point
Solution: (1)Opposite direction; (2)Control card was wrong; (3)Limit Switch was wrong; (4)Drive was wrong; (5)Stepper motor was wrong.

10. Spindle can’t stop
Solution: (1)Control card was wrong; (2) Transducer was wrong.

Common fault & Solution about CNC Router(1)

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

Solution:
(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

Solution:
(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

Solution:
(1) Controller card was wrong/loose; (2) Driver was wrong; (3) Stepper motor was wrong; (4) Motor line fault; (5) Electrostatic interference; (6) Data cable fault; (7) Files route was wrong; (8) The equivalent coupler was breakaged/loosen; (9) So fast High-speed; (10) Computer wrong/virus

CNC Router machine’s routine attention

Posted on by

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.
