Hello,

We have an UR10e which has a really slow boot time (approx. 5min) with the latest SW 5.8.2 update. After the update I noticed constrained freedrive is not showing up, but the rest was working fine. We have another UR10e (running perfectly) so I checked the version numbers and they were both the same "ver.5.8.2.10297". 
It has URCap 1.5.1 with 2F-85 gripper but there was no problem with that.

I wanted to check some solutions from forums for the boot time but it didn't boot up. It shows the three dot loading screen than the "Debian GNU/Linux 8" screen and nothing else.

Any suggestions would be appreciated.

Cheers,
Levente

We’ve had similar boot issues on several of our UR10e robots. Our solution with help from UR was to build a new SD card. If you go to downloads and download Robot Software Image you can get a full image of the robot. You will need to follow the instructions they give you for burning a new SD card using Rufus. 


You only need to place the calibration.conf file back into the .urcontrol folder. You can mount the existing SD card and get that file off of it. It’s at /root/.urcontrol/calibration.conf  

BTW, if you install Beacon on the robot it will keep all of your files synced to the cloud and if you ever have an SD card fail you will have a full backup of all your programs and any needed files to rebuild the SD card. 

For the constrained mode, did you enable it under settings?  There is the ability to turn that on or off in settings.

Thank you for your answer.

I tried to get the calibration.conf file but with FileZilla I cannot connect to the cobot and if I insert the SD card in a laptop it requires formatting. So I'm stuck at this point. 

Is calibration.conf file universal? Can I use it from another cobot or I have to use that file from the cobot which is not booting?

I will check the constrained mode in settings.

You can get the file from UR as well. Your distributor should be able to get it for you. Last time I had to get it, corrupted USB on a CB3, it took a couple of hours and I had it.  They just need the robot serial number. 


It has to be that robot as that is the actual calibration of the arm. Otherwise you will not have a calibrated robot.
