hector-mapping Lookup would require extrapolation into the future

Hello guys, I'm generating a map with hector mapping, I have the follow system:

I installed all drivers, launch the system and hector_mapping generate a good map.


I copied this same system on a pc with native Ubuntu 16.04, launching the system I have a problem: on rviz the laserscan topic blink with this error:

For frame [laser]: No transform to fixed frame [map]. TF error: [Lookup would require extrapolation into the future. Requested time 1542901381.561356359 but the latest data is at time 1542901381.541110389, when looking up transform from frame [laser] to frame [map]

I've been trying to understand why this is happening:

I read that could be a synchronization problem trought multiple pc, but in this case I have only one pc.

I don't understand why on virtual machine works all good while in the native ubuntu machine I have the flickering topic.

Thanks in advance.

Hi, I got the same error in rviz. I increase the Queue Size in the LaserScan tag from 10 to 100 to make the laser scans show up. -Chad
