A video on network troubleshooting is available here:
The Network Setup manual is designed to help the user set up the connection with the controller. Upon opening the Network tab, you are presented with the following window:
NOTE: The controller IP address MUST be located in the same local network as the LAN connection to the host computer (for example, 192.168.4.50 and 192.168.4.78 - note the 4
in the third octet). However, this address must also be unique to clearly indicate to the host computer where it should send commands to.
The default IP address for most myCNC boards is 192.168.4.78. For certain older boards (typically purchased before 2017), this default IP address may be different, usually being 192.168.0.78. Note that if that is the case, the host computer connection is then also required to have a 0 in the third octet.
The message/packets counters allow for quick network diagnostics when using myCNC software. These indicate the number of messages sent, messages resent, as well as incoming and outgoing packets lost. Note that single digit packet loss is normal when first turning the controller/software on and as the connection is being set up since the message number that the controller expects will differ from the once sent from the myCNC software after restart. However, it is recommended to watch the packet loss number over some working time period (half-hour to an hour) to see if there is a constant packet loss occurring after the software setup has been completed. If continuous packet loss occurs, it indicates problems in the connection between the host computer running myCNC software and the controller.
Accept Command Buffer Lags toggles the acceptance of lagging commands that are sent to the controller despite the delay indicated in the command buffer window below. This is usually done when the number of network commands per second is very large (in the hundreds/thousands), and can lead to unexpected jerks of the machine due to sudden speed changes. This setting is recommended to be used in an experimental fashion.
Job started Timeout specifies the time (in messages sent) between the signal for job start and the maximum allowable point at which the controller has to send a signal back to the host computer to confirm that the job has indeed started. This is set to be 15 by default - setting it much lower will result in the controller not having enough time to send a response signal to the computer, while setting it much higher might result in the computer taking much longer to process each individual user command.
NOTE: If you do not know the IP of the board, or if you want to change it, please consult the Change IP Address of myCNC control board network manual.
