I’m just throwing this out to you guys to document it. I know it’s been said but others, but I decided I probably needed to say it about my machine as well.
quite frequently when it is calibrating it will move up the left side (the home side) and then it’s like the head tried to move farther left and appears to get in a bit of a bind. You can see the head pop up from it’s base on the left side. Sometimes it corrects itself and moves on toward the center to find the camera. Other times you can hear the loud popping that I’m pretty sure is the head trying to move even farther left, but of course it can’t. At that point I will usually turn it off and move it to the center by hand. In fact, I tend to do that most times, and the majority of the times I do not It seems to have this problem.
