@rfancella, if you have a multimeter check for a short. And, if you can, take a picture of the connections and post it here. I'll see if there's anything I...

They're not so bad tbh. Happy to hear about the performance with a change in bootloader. Thanks for letting me know, @rfancella. I've got the same controller layout on my...
