Re: [Playerstage-users] Laser settings for Player

[ahoward <ah...@us...>]

Hi Jason:

Are you sure that the ratio is not *exactly* 10 to 1?  If so, you are
probably running the laser in 1cm mode rather then 1mm mode.  In theory,
this shouldnt happen, since Player sets the laser to 1mm mode when it
initializes.  Are you using some other piece of software that sets the
range mode, perhaps?

BTW, I recently added support for the SICK's other range modes to Player;
you can now operate it in 1mm, 1cm or 10cm modes.  The only real advantage
to the latter modes is that the max range goes up from 8m to 80m and 800m,
respectively.  If the range mode settings do turn out to be your problem,
you can try installing the latest Player snapshot from here:

  http://playerstage.sourceforge.net/snapshots/snapshots.html

and setting the range mode to 10cm in the configuration file.
