 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.  NOTE: The ET7 controller has two encoder slot reserved for the ET7 keyboard panel.

-If you use the ET10 controller [[https://shop.pv-automation.com/et10/9-mycnc-et10.html]], you can utilize not only the MPG function, but also the dedicated encoder inputsto monitor the current position of any of the machine axes.

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}}

-====ET10 MPG connection through encoder inputs====+    * 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:

For example, for fast encoder #5, parameter 105 will be chosen.    * For the **parameter**, type in some parameter 100-112 for fast encoders (0-16 is reserved for slow encoders).
