I've set up my first K40 laser and have a problem with the home position. When the unit is turned on, it moves to the top of the Y axis and hits the end-stop switch/sensor like it should, but then it starts moving to the right along the X axis. I can never get the laser head to the home position (top-left corner) unless I move it manually. Every time I turn the machine on, it moves the laser a few inches to the right. Here is a link to a video I made that I hope shows the problem. https://youtu.be/1VGPBVDV4Rc

Thank you!
