 +NOTE: The ET7 controller has two encoder slot reserved for the ET7 keyboard panel. These are permanently assigned to inputs #16, 17, 18, and 19, and cannot be changed despite editing the Config window (the preset cannot be overridden). If encoder input slots are to be used on the ET7 board, the latter two slots (2 and 3) should be used. This preset is not present on the ET6/​ET10/​ET15 boards where encoder slots 0-3 can all be used.

 +====ET10 MPG connection through encoder inputs====
 +
 +The following diagram shows an example of an MPG wheel connection to the ET10 controller (encoder #5):
 +
 +{{:​mycnc:​et10-connection-encoders-mpg-002.png}}
 +
 +In order to set up this encoder to change some values within the software (such as jog overspeed, motion overspeed, etc) or to jog axes, 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. ​
 +  * For **destination**,​ select Item.
 +  * For **destination parameter**,​ input the parameter you require (for example, jog-overspeed)
 +  * Set K to 1, leave K0 blank. ​
 +The settings window should then look similar to this: 
 +
 +{{:​mycnc:​mpg-encoder-setup-002.png}}
 +
 +This will allow us to use the MPG wheel connected to the encoder inputs to change a number of myCNC parameters. ​
