Analysis of the mechanical failure for CNC Router

One,An axis or three-axis for stone cnc router does not move or move with abnormal;
Reasons :
    1.loosened or problem for Weihong Card ;
    2.Problem for corresponding drive of three axises;
    3.Problem for corresponding axis step motor;
    4.Relative shaft between ball screw and motor is loosened or broken out;
    5.Relative ball screw or screw nut is broken out or has problems;
    6.Relative slips of axis has problems ;
    7.The parameters,current of drive is different from software;
Two,Z-axis for stone engraving machine is out of control ;
Reasons :
    1.loosened or problem for Weihong Card ;
    2.Static;
    3.Motor lines for Z-Axis has problems ;
    4.File path is wrong;
    5.Inverter interference
    6.Computer system has problem or has virus;
    7.Operating is wrong

Three,Wrong for tombstone engraving machine;
Reasons:
    1.loosened or problem for Weihong Card ;
    2.Problem for corresponding drive of three axises;
    3.Problem for step motor;
    4.Static;
    5.Problem for motor lines;
    6.Problem for data lines;
    7.Problem for file path;
    8.shaft between ball screw and motor is loosened or broken out;
    9.Working speed is too fast;
    10.Computer system has problem or has virus .
Four, The irregularities in depth for engraving of granite engraving machine;
Reasons:
    1.loosened or problem for Weihong Card ;
    2.Problem for step motor;
    3.Problem for drive or setting for current is different from software ;
    4.Problem for Motor lines of Z-axis ;
    5.Problem for Spindle motor ;
    6.Inverter interference or setting for data is wrong;
    7.Static;
    8.Computer system has problem or has virus.
Five, Engrave randomly ;
Reasons:
    1.Problem for weihong card;
    2. Interference;
    3.File path is wrong;
    4.Static;
    5.Setting in software has problem;
    6.Problem for drive or currents setting is wrong;
    7.Problem for data line;
    8.Computer system has problem or has virus.
Six,Milling bottom is rough ;
Reasons:
    1.Spindle and table is not vertical ,and need to adjust;
    2.Blade has some problem;
    3.Ncstudio control card has some problem ;
Seven, Spindle stop to turn;
Reasons:
    1.internal short circuit of Spindle；
    2.Current shield
    3.Parameters of setting for Inverter has problem or inverter has problem;
    4.Problems for Weihong card ;
    5.The spindle lines or data lines short-circuit
Eight, Spindle rotation sounds abnormal;
Reasons:
    1.Setting for inverter has problems;
    2.Spindle donot work;
    3.Spindle has problem.
Nine, The direction of Moving or back to mechanical origin is opposite ;
Reasons:
    1.Modify the file of “Public.dat” in the notebook;
    2.Modify the ways of connecting lines for Inverter;
    3.Modify the direction in Ncstudio window .
Ten,Machine couldnot go back to mechanical origin normally ;
Reasons:
    1.Direction is opposite;
    2.Weihong card has problem or loosened;
    3.Limit switch or data line has problems;
    4.Drives have problems;
