[Playerstage-users] Laser behaviour with "super-high" resolution

[<ama...@ma...>]

Unintentionally tried to request 0.005 degree angular resolution from a
SICK laser. It puzzled me for an hour, so I'll submit it simply for
archival purposes.

Symptoms:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Laser driver is trying to connect,
Getting multiple "timeouts"
Eventually quitting with an unsual error: "variant request ignored"
The laser now sports a red light, pretends to be dead and has to be
power-cycled.

Cause:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Config file had an erroneous entry
...
resolution 0.5
...
instead of 'resolution 50'. Don't know what the laser was trying to do bu=
t
it didn't like doing it.
