Setting up the myCNC control board

Connect 24V DC power supply to myCNC control board
- Here are power-up examples for ET6, ET7, ET10 control boards
Connect myCNC Ethernet controller with Network cable directly to Host computer or to Network Router. If use Odroid-C2 (Raspberry-Pi3) computers as a Host, Network cable is a short 0.5ft cable between Odroid & Controller
Setup Network addresses for Host computer and myCNC Ethernet controller. Addresses of Controller and Host should be in same local network. For Example -
```
Controller Address: 192.168.0.78
Host Address: 192.168.0.100
```
or
```
Controller Address: 192.168.5.10
Host Address: 192.168.5.11
```
Look here if need to change IP address of controller board
Goto MyCNC software, Cfg Settings, Network Tab and
- Set actual Controller IP address to “Controller IP Address” to tell the software where it can find myCNC Controller,
- Set “Network Protocol” to “UDP”,
- press “Save” button on the top-right of myCNC screen.
- Changes should be applied on the fly and UDP message counter should start counting which means communication between Controller & Host works correct.
Connect Pulse-Dir signals from servo or stepper driver to myCNC control board
Check what minimal pulse width your drivers accept and set pulse width of myCNC control board accordingly (equal or more) in MyCNC software → Cfg Settings → Hardware Tab → Common Hardware Settings MyCNC-ET6, myCNC-ET7 controllers support separate pulse width settings for the first 4 channels (#0, #1, #2, #3) and the rest 2 (#4, #5). This option can be convenient if use high performance servo drivers with low psed stepper drivers (for example high speed servos for X, Y, Z axes and low speed stepper for rotational A axis). myCNC-ET10 controller use only the first pulse width selector for all motor outputs.
