Use correct cable
Are the cables correctly plugged in?
Is the arm button switched on?
Frequent USB disconnections
In some environments, when the voltage difference
between the table, part and probe tip build up enough it
can cause an arc.
This can sometimes affect the USB Signal.
An improvement is to connect the grounds of the
computer, arm and table together.
Ensure that the arm is plugged on a 3 really connected
prong plug.
Ensure the PC has a 3-prong plug. Certain computers
are not always this way.
Plug the PC and Arm into the same surge protector.
Connecting to the same ground is best.
If the Arm and part are on a metal table then it is also
helpful to ground the table or part to the same ground as
the arm and PC.
Additionally, some factories where heavy equipment is
present (Arc welders, etc.) can cause surges on the input
power.
It is recommended to use a different ground for the Arm
than is used for the arc welder. Also, a power conditioner
that will filter the power supply will help in this case. Arm
and Computer should be plugged into power conditioner.
With my NC tube probe, the points
are not taken correctly
Check that the environment light doesn’t interfere with the
infra-red beams.
When I converted from SI to SE, I
saw that a 15mm probe was saved
for the offset position in the list of
probes. Why is this?
This is because any 7 axes arm needs one centred probe
and one offset probe to be calibrated. Any 7 axes arm
(V1, V2, V3, SE, SI, SEI) always contains 2 reference
probes
