plates (measured in wheel MSteps). If each plate holds only one target in its
center, then the distance between targets is equal to the plate’s distance. The
controller automatically calculates and updates the Plates Distance parameter
according to the Plates value.
To update the Plates value:
a. Press the Plates field
. A floating Keypad opens.
b. Using the Keypad enter your value (in MSteps) and press . The
