I’m using a dual focbox 6374 setup. Running bldc 12s.
Also using the photon advanced remote, but have used diy’s nano remote previously. Same problem.
if the vescs are on for 10 minutes or more, the motors start moving and jerking on their own. This can throw me off the board. They start moving really slowly at first, unnoticeable when riding. But then you notice it.
I often ride around and notice the board acting a tiny bit weird. Then i jump off and pick it up, and the motors are going backwards and forwards, by themselves.
When the motors have started jerking on their own they just jerk more and more, they never stop.
If i don’t cut the power they would eventually spin with full throttle, then go full throttle reverse etc, never stopping. It would ruin my vescs. As i said, they start real slow, only jittering until they start spinning.
I have to reboot the system to get rid of it (yes i have to restart my eboard every 10 minutes when i ride)
I used Y split receiver setup before, now canbus, but the motors jerk independently, as always.
Interferences somewhow… Do you have a ferrite on your PWM cable (the one from the receiver to the ESC) ? Does your problem occur everywhere or just around a specific place ? Is your receiver really close from the phase wires (the ones going from motors to ESC) ? Check if your cable are not too close from each others (signal cable VS power cable)
Did you just finish this build or did it work well before and just start going weird ?
Any pictures from your enclosure layout to help us ?
Well I this build was “ridable” a year ago, but I haven’t been able to trust it because of weird problems like this. So it has been on pause for a long time. I gave up on it.
So yes I have had this problem since the beginning.
i tried moving the receiver as far away as possible, but to no help. The board is still acting really weird, sometimes. The problem can happen anywhere.
I though it was an interference from the battery or so but this issue happened only in one motor so I switched between the receivers and it happened again on the other motor.
It happened inside and outside a carbon fiber enclosure.
A calibration helped in my case though.
Well i just did a small test outside on my terrace. I throttled from standstill, then the board suddenly
throttled by itself, continuing for a second even after i left go of the throttle stick.
I don’t understand how that could be fixed with a calibration.
This is exactly the kind of problems i have, which no one has answers for, it seems.
The entire year i have had this board, i have not felt safe, even though i have had fun.
Please help me make this skateboard with expensive worthless electronics on it work, so it could be usable.
Jumping in here. Sensor motors? 2 years ago this happened to me. It was either bad sensor cables or power wires.
Also do yoj callibrate the nano remote every time.befor riding?
Vescs are 3.38. It was 2.54 before I updated. Dual foc boxes.
Well this project has been on pause for a really long time so all I’ve used to keep everything together is duct tape. I received a really nice enclosure from eboosted yesterday though, which I will mount soon.
I hope I didn’t miss it somehwhere. Using the ferrite ring is important to clean up the signals running through the receiver wires. Do you have it? Hopefully you can get this problem figured out.
