   * If necessary, select the coordinate axis which will be controlled by MPG. This will allow to move the machine along that axis when the MPG wheel is turned.

-  * We set the resolving power of the MPG - the number of pulses per one revolution of MPG. Note that since this number will be counting not the number of clicks (for example, 100 clicks/markings around the MPG wheel dial), but rather the number of pulses sent by going through one full rotation of the MPG wheel. Therefore, this number is typically found by taking the number of markings/lines for one full rotation of the MPG wheel and multiplying it by 4 (for example, 400 pulses for 100 clicks). {{:mycnc:encoders-007-mpg-0.png}}
+    * If using a software pendant approach while having selected a particular axis (for example, by using the hotkeys to switch the step size while only using the MPG wheel to control the X axis), you can enter ''soft'' into the Dimension field so that the length of displacements uses the pendant value.

+  * The encoder resolution is hard-coded to be 65536.
     * This is different from encoder setup in the Settings > Config > Hardware > Encoders section. In here, it is the number of lines/markings on the MPG wheel for one full rotation that must be specified, as opposed to the number of pulses. Therefore, you would put ''100'' if your MPG wheel had 100 lines in this section:

+As already mentioned, axis control can be set up directly from the //MPG through binary inputs// settings window. In order to set up this encoder to change some values within the software (such as jog overspeed, motion overspeed, etc), the user can go into Settings > Config > Inputs/Outputs/Sensors > Connections, and add a new connection or edit an existing one.
   * In the **Source** field, select Encoder.
   * For the **parameter**, type in some parameter 100-112 for fast encoders (0-16 is reserved for slow encoders). In order to check which particular encoder is used, the user can go into Settings > Config > Hardware > Encoders and note which encoder value changes as the MPG wheel is being turned. For example, for fast encoder #5, parameter 105 will be chosen.
