Well I got it installed and powered up and when I turn the printer on I get the expected 2 blinks....however IF I have the printer powered off and I connect the USB from my OctoPI the board will flash the LED 4 times. This is before powering up the printer. If after attaching the USB power I power on the printer the LED does nothing at that point and my Z home setting keeps getting higher and higher, it is now at zero about 5 inches above the bed. If I have the USB disconnected and I power on the printer I get the expected 2 flashes . Is this how it is supposed to act? This will make it a real pain to use if I have to disconnect the OctoPI before powering on the printer. I just can't think what might be wrong...help? Currently I am running the 1.1 firmware from about 10 days ago, but not RC8 and I have not gone through and made the changes in firmware and uploaded it yet. Would that cause this? Off to get RC8 and make my changes.
