CNC engraving machine, uniaxial and triaxial don't go for a walk or move around is not normal

CNC engraving machine, uniaxial and triaxial don't go for a walk or move abnormal reasons: 1. Loose control card or failure; 2. Corresponding to the shaft drive failure; 3. The corresponding axis stepper motor fault; 4. Corresponding to the shaft broken or loose ( Even the axis loose symptom, carved font dislocation) ; 5. Corresponding to the screw fracture or screw nut fails; 6. The corresponding axial sliding fast failure; 7. Drive fine fraction, current, and software setting is different.
