Hi, I converted to the navigator board and initial bench testing was fine. But after about 15 mins in the water the vertical motors run flat out and then communication is lost. Then it re-boots. Bench testing; stabilise mode the motors run slowly, if I put a yaw or sideways input comms is lost agai…

Interesting thought on the power, I have not checked the battery under load. I have a number of spares so will try them. The logs attached are the BlueOS logs, downloaded just as you described. Yes I am using Blue OS 1.1.1

Hi Terry - Those logs are ardusub logs, not the logs of BlueOS itself. When those download, it will be named system_logs.zip . You can find that menu in the bottom left corner, here is a better screenshot to orient you: [image]

Hi Anthony, apologies - lets try this file: system_logs.zip (3.5 MB)

Hi Anthony, have you managed to have a look at my latest log yet? Thanks.

Hi Terry - Sorry for the delay in response! I don’ see anything weird in your logs. Can you share information on how you are powering the ROV? What battery, and if you’ve modified the power connections in any ways? Have you made any other modifications to the system? This was an R1 or R2 BlueROV…

Hi Anthony, No problem. The ROV is normally powered by an 18000mAh battery but sometimes I use a 10000mAH. I have used these many times before without issue. I have not modified the power supply in any way. No other modes apart from my own frame and motors. Upgrade to navigator with a raspberry …

Hi @Teggles - That’s wild! I would guess that something is screwed up with your installation and/or parameters. I would recommend downloading BlueOS and flashing your SD card, and setting up the vehicle from scratch. You could alternatively just reset and load the default parameters . Either way, t…

Hi Anthony, I have reflashed thé sad card, reset default parameters, calibrated etc. Changed a couple of cables. The heat sink is new but I will look at it again. Looks like I will need to go back to the dealer and ask fo a change of board. Thanks for the help, really appreciate it. Kind regards…

Well, I have changed the navigator board, changed few vertical parameters but still when depth hold is selected the vertical motors run to full speed. I have reflashed sub 4.1.1 and gone back to 4.1.0. No change. I have replaced just about all the hardware, updated/rolled back software, and I still …

Hi @Teggles - You may want to verify this setting: [image] You may also need to calibrate your joystick: [image] Did you update to a newer version of BlueOS than 1.1.1? Maybe 1.2 beta 6?
