I'm just at the stage of setting up the heads to the home position. I have setup the IR sensor and managed to pull the centre glass plate clip off with the heads (dual) as the heads move to the home position. So Y end stop needs adjusting. What would be good would be an overview of the homing procedure rather than a series of steps where some instructions are given for the Pro and Lite (Single), then some for Dual etc. which is a lot of scrolling and losing your place of where in the calibration process you are. An overview of one liners, and a basic knowledge of menu commands would (for me) be a lot simpler than scrolling through a lot of images and brief instructions on what command to issue. Also it is impossible to see where on the grid the head is to see if you are at the home position.
