If the machine is not operating and the” information light” next to the power button at the rear status panel of the machine and the firmware LED on the logic board flashes with the following eight-bit pattern as described here:
...
This error is detected if the machines machine's position of an axis differes differs from the desired position by some threshold. This can result of in occasional load disturbances and these are harmless. It is also the most common fault to be triggered by a collision event. This error can occur on all three axis axes but the debugging procedure is always the same.
...
Check all the encoders, encoder interpolators, and encoder cables.
Check that the drive is mechanically aligned, smooth, no slop/slipping, etc.
Let service know when the faults occur, of particular interest:
Only during initialization/volume calibration
Only in certain areas of the volume
Only near the limits
Only on long moves
Only on short moves
Only while using a touch probe
Only when the touch probe touches the part
Only while using the pendant/on-screen joystick
Only when using the rapid mode
Only after the machine has been running a long time

Axis Hardly Moves at All or Does not Resist Pushing
...
Check that the rotary encoder is properly connected and aligned to the motor shaft.
Check that there are no loose components in the drive. A loose Loose coupling can drive the machine slowly but not quickly.
Check the encoder scopes in MotorScope to make sure they count as expected as the stage is pushed around.
If an encoder counts faster in one direction than the other, it is very likely a bad encoder cable.
If pushing one axis causes counts to change on another, it is very likely a bad cable on the axis not being moved.

Fault after Grinding or Whirring Sound in the Motor
...
This could be caused by an improperly set antigravity bias , and can occur after adding or removing sensors to the z-axis.
Recalibrating the volume will remeasure the antigravity bias.
...
This can be caused by the machine touching the hard stops because they are too close to the encoder limits, and is especially likely on Vertex machines. Move the encoder limits away from the hardstopshard stops.
