Perhaps there is somebody who would be kind enough to share their Marlin file with mike. It would help a lot to have one that does work the lcd to examine for his error with it? I know the stepper numbers will be different and so on, but having a copy that we know works might make all the difference.

Mike, even if you switch back to the first one, we know the couplers are a problem. A weak spot that must be fixed. Lets do that anyway??
