Changes axis' encoder counts per mm.  For example, doubling this number would cause a given number of mm to be converted internally to twice as many encoder counts as before.  A command to move the stage 2 mm would instead cause it to move 4 mm. **MOST USERS DO NOT NEED THIS FUNCTION!**  If your stage is not moving as expected try making sure the leadscrew pitch is set appropriately with the ''[[commands:customa|CUSTOMA]]'' command.

\begin{equation} Cnts = {(6.5536 * 107) \over d} \end{equation}

where ''d'' is the total range of movement in microns. For example, if the range of movement is -100um to +100um, then ''d = 200'', and ''Cnts = 327680''.

**Note:** For a piezo device, always set **CNTS** first, then limits (**SL** and **SU**) afterward.

== Example: ==
	

<asi> $ C X=13490.4
:A
$ C X?
:X=13490.4 A</asi>

Changes the encoder constant on the X-axis to 13490.4 counts/mm.  The default values for this parameter are restored upon reset and should not require user modification.
