@Surtz said in CanBus Problems:
I had a look at machine setting and it showed that the Mini5 had 3.5.6
We haven't released a firmware version 3.5.6 so I guess you meant 3.4.6. Between major firmware versions (e.g. 3.4.x and 3.5.x) we often change the details of some of the messages sent between boards over CAN, so it's not unusual for some thing not to work when you mix versions in this way.
