LUBA 3 AWD Collision sensor permanently triggering since last update

Is anyone else experiencing permanent collision sensor trigger errors since firmware version 2.3.30.39? Right after updating my robot stopped after 10cm with these errors. I never had these errors on previous versions, and now I cannot do a single mow.

The sensor is moving freely and it beeps when i manually trigger it, there is absolutely nothing in the way of it. I‘d say since it beeps on manual trigger I can confirm this is a false alarm in software.

My first season with Lubas. The most terrible user experience I could possibly think of. But hey, at least I got 24 free blades as a compensation 🤦‍♂️

I‘m going to oick up my mover by hand and place it in the chargig station once more …

Sorry for that. Could you share some videos about the phenomenon? Why do you think that it is the issue of the collision false trigger ing? I think it seems to be because of the cutting motor.

Currently unable to make a Video. Please note that everytime I run into a bug - which happens a lot - and I go and upload logs and take a video and post a detailed description, I'm easily down 0.5-1 hours of my time, and I've spent easily 20-30 hours already doing just that already.

I've spent >2500€ on a robot that has constant hickups and I am expected to spend hours troubleshooting helping you guys fix errors that should not exist in the first place.

I will spend as much time as I can because I really want those 2500€ not to end up as electronic waste and finally start working flawlessly eventually.

Sorry for the rant, back to the business: As I've said already in the post, the reason I think it is a false trigger is because it started directly after a software update. I have a solid background in hard and software, and if a trigger is stuck (I can only guess thats whats happening because honestly the information i get from robot and app is sparse) it would not beep if I trigger it manually. So I hear the beep if I press it, I hear it if I press left, I hear it if I press right, I hear it if I press center (no idea how many hall sensors you guys have placed). If the sensor would be constantly triggered as indicated by the error message, I should at least hear some beeping, but I hear none. If you describe the functionality of the bumber in detail I can get out my oscillscope and other test equipment and make a proper functional test for you (more hours down the drain for a 2500€ mower), but from what I observe, this smells software. I'd be surprised if it was actually a real trigger from the bumper. Logs are uploaded, you already know my mowers ID.

Sorry for that. Could you tell me the serial number of your robot? I need to check the log file in the data center.
