Hi, all. I took a long (several month) mental health break from my printer, but came back to it this week. I had been having terrible trouble with Z homing, and the behavior of the Z axis in general, which I thought might be at least partially due to some interaction between Octoprint and the printer. Conventional wisdom here was that it was probably a mechanical problem. After replacing the Z axis bearings, switching to spider couplers and recommissioning the Z axis a few times, I got to the point of repeatable, if not perfect, results. So, I decided to connect Octoprint again. And all my problems returned. Z homing became completely unpredictable. OK one time and then driving the bed into the hotend the next. And the Y homing behavior changed, too. Though that had never been a problem before. I had to back out the Y endstop screw quite a bit. I think I probably contributed to the unpredictability by power cycling the printer in my any attempts to reposition the IR sensor, so probably sometimes the Octoprint had established a connection, and other times no. I disconnected Octoprint this morning, and spent an hour or so recommissioning the Z-axis and am printing again. So while my original question was "Can Octoprint affect the homing behavior of the BigBox?" I'm now pretty certain that it can, and my question becomes, "If yes, then by what mechanism?" EDIT: I should add that I was using Octoprint only for the camera. I entered the parameters provided in the e3D build documentation, but was not using Octoprint for any kind of machine control.
