Engraving machine failure often appear

1. Boot after the workbench to. Axis direction reason: first check the left column above switch & other; Y/shaft & throughout; Whether the plate to the wrong & other; X axis & throughout; To; Check wiring is strong; Check that the light inspection for damage; 。 Axis stroke switch reed not bounce; Check whether the adapter plate is water, cause a short-circuit. Method: the switch & other; 。 Shaft & throughout; To to plug cable, check that the light inspection signals is normal in 012342, replacing the normal light. Again and again according to the reed switch, reset, or change the stroke switch. Use hair dryer will transfer board dry or replace the adapter plate. 2. Boot after the nose to run right reason: check damaged by put in on other objects; Check wiring is strong; Check the beam part whether light inspection line and line of the travel switch circuit due to movement; Travel switch reed not bounce; Check whether the adapter plate is water, cause a short-circuit. Excluded methods: beam allowed on other objects. Will spare light change according to the sample. Plug cable again. Replace the cross beam cable. Again and again according to the reed switch, reset, or change the stroke switch. Use hair dryer will transfer board dry or replace rotating plate. 3. Boot after head back to the origin reason: check check block slice to block light inspection; Check the CNC engraving machine head after the sliding box body for sundry. Method: to install light and block slice, clean up after the sliding body of sundry. 4. Boot after head downward movement: check whether beam light inspection line open circuit due to movement; Check wiring is strong; Check that the light inspection for damage; Check whether the adapter plate is water, cause a short-circuit. Elimination method: replace the beam cable, plug cable, wash with alcohol inspection or replacement of light, use hair dryer will transfer board dry or replacement. 5. Appear in the manufacturing process of a shaft misalignment reasons: to check whether there is loose coupling knot; Check whether the pressure bearing end cover is loose; Check the wiring is rigid, Especially the dislocation drive shaft section) 。 Elimination method: fastening coupling on the socket head cap screw or replace coupling knot, the end cover along the screw clockwise, then use screw locking. To plug the problem. 6. Boot alarm reason: check whether the stop button is pressed, and lock the no pop-up; Check whether the switch is no bounce; Testing machine transfer board whether the travel switch wiring short circuit; Check machine connecting plate on the back of the solder joints and metal surface contact cause a short-circuit. Elimination method: will stop button pop-up, replacement travel switch, welding line, again to pack machine adapter plate, its from the metal surface.
