I seem to be having trouble with downloading programs from my Picaxe Programmer to my Picaxe-40x2. A lot of times I get communications faults and have to reset and try again.
Worst of all, sometimes these errors are accompanied by somewhat distrubing behavior for the bot itself. It seems like all the servos are being forced to turn very far to one side. One servo (a DAGU mini) in particular seems like it is trying to turn itself past its limit.
