Thanks @Deckoz. I found that out the hard way. I inadvertently loaded 4.8 firmware. I blown like 8 fuses trying to diagnose. Just got it figured out when you posted.
Where do I find 3.100 firmware? Is this Ack’s? I can only find 2.54 which messes with my remote somehow.
i just cant find the post i was looking for, there is a possibility to fry your DRV/CAN Chips when using CANBUS and the cable is not connected, was it when powering on the vescs not at the same time?
want to update but do not really know right now how to. just unplug can bus cable and do it for every vesc?
If you don’t power on the vescs simultaneously there will be a voltage difference and one can bus will leech power from the other. That’ll result in a fried can chip and possibly drv too.
Interesting. I’ve got the 3.1 firmware loaded but my motor now fails on detection. It does turn while attempting to figure things out. This worked on 2.18. Any thoughts?
