My problem was just the stepper deactivate timeout. It was intermittent because I had a couple of tall jobs and lots of short ones I was printing. Increasing the timeout solved my problem. It always works for me now.

For the waiting for user issue, I had that at one point when I had pronterface connected, polling the temperatures. I took a tip from another forum and turned the temp graph off and all is well now. The temperature monitoring in Octoprint doesn't seem to cause this.
