[QUOTE="a33, post: 1109834, member: 332642"] The motor-zero defines where the highest point of your rotation-arc is. Apart from this motor zero, your dish should be mounted on the axis exactly in line while motor is at zero. This is also difficult, to get to 0.1 degree exact. (You can try measuring sides of dish to back of motor; left and right should be equal, if all brackets are symmetrical.) For the combination motor + dish, thankfully USALS allows you to pick any satellite you like, and align to that satellite. That procedure also sets your due south/north right. Checking at the east/west extremes, you get a chance to correct/finetune your angles; including your motor zero, and dish outlining with the zero position. Greetz, A33 [/QUOTE]
