This firmware and hardware can work on so many different machines and a simple typo can make so much go wrong, that we have to have the config to even begin to diagnose anything. That being said, great job finding your problem before anyone else had a chance to 🙂
I do have a delta with a 0.8.5 board but it sits unused 6 months out of the year probably… I'm thinking of decomissioning it to salvage the motors for a CNC Router 🙂 and move the 0.8.5 to one of my other printers
