I’m experiencing an annoying issue with one esc.

The motor connected to the slave esc sometimes doesn’t work, while the motor connected to the master esc always works. The weird thing is that if I don’t do anything but unplug the loop key, wait a few minutes and then power up again, everything works fine (sometimes I have to do it more than once). I even went for test rides when both motors worked and I had no issues with them. I thought that it could be a canbus problem but after a continuity check I can tell that the cable is not damaged.
Yesterday I opened the Vtool and checked if I had set any wrong parameters but while I was looking for an error this flagged on the screen:


and after that MOTOR ID: 90 disappeared

so I went ahead to Scan CAN but it could find nothing.
I closed the Vtool, unplugged the loop key waited a few minutes, retried and same as before all of a sudden one MOTOR ID disappears. Weird af because when I went for test rides, once that the motors were working both never stopped.

Please let me know if you ever experienced this kind of issue and how did you solved it =(

Wow, that sounds scary.

Are you 100% sure it’s not a CANBUS cable problem? Have you tried swapping which ESC is the master? Have you tried a new CANBUS cable anyway?

What hardware are the ESCs? Are they running the exact same firmware version? Maybe save all your settings and try updating the firmware on both ESCs individually, and then verifying the update sticks after a >10 second delay and a reboot.

What happens if I leave the uart connection to one esc (because I soldered it in the master) and just connect the slave esc ppm cable to the reciever swapping it with the master one? I don’t have any other canbus cables so I have to buy a new one to try, I don’t remember what firmware version it is but I’m 100% sure that it’s the same on both escs

I don’t understand how it’s connected now

Sorry, master esc is connected with uart and ppm to the reciever and slave esc is connected to master esc via canbus

Oh yeah I’d try what you suggested then.

In the firmware tab, are both ESCs reporting the same version?

Hai,

I looked at this diagram and I wondered if connect another two 4s1p batteries to charging ports connectors. would it to be 4s2p and finally 8s2p? :thinking:

keep in mind that originally for charging this wiring should have additional antispark on black cable in the middle between batts
