Motion Console Diagnostics
There are a number of possible problems that can be diagnosed by the systematic use
of the Motion Console utility. One of the more common uses is to isolate a suspected
defective motor axis driver board.
This procedure demonstrates one method of using Motion Console to determine the
exact cause of a machine malfunction.
Reported problem: Machine makes loud grinding sound when moving / trying to cut.
Possible causes: Cutting head stuck behind clamp button, gantry jamming against
stationary object, defective stepper motor or cable, defective motor driver circuit board.
Diagnostic procedure: Check for obstructions to cutting head and gantry movement;
clamp button interference, shelving or other furniture, or T-nuts left in the frame jammed
between the bearing cart and extrusion. Check motor cable connections.
If none of the above are found to be the cause, proceed to Motion Console screen.
From the Hardware Summary screen, select Controller 0, Axis 0 to operate the X-axis
motor. Click Relative Mode and the Enable radio button, check the Axis status indicator
for “No Event” or “Normal” State. Click the Clear Fault button to clear, if needed.
Release the Emergency Stop knob, and press the Enable button on the controller.
Click the right, then left arrow buttons to move the X axis right and left. If the motor
moves as commanded, the following assumptions can be made regarding the X-axis
portion of the system:
• Power supply and X-axis fuse – OK
• X-axis motor and cables – OK
• X-axis driver board - OK
