HI all,
I lost my ethernet connection to my laser after installing an Ethernet smoothstepper on my cnc (I use a laptop to run both laser and cnc). I am not an network expert but any help would be appreciated. Running Windows 10, RDworks 8.01.21. (USB works ok but I'd rather use Ethernet)

Thanks!

Most likely the IP address is different than what you were using before. Did the new controller come with documentation? You should need to set the IP Address, subnet mask, and default gateway on the controller.

In Windows 10, go to the search bar and type "cmd" and select "Command Prompt" from the list.
In the Command Prompt window type

Code: Select all
ipconfig /all


Find the entry that reads "Ethernet adapter Local Area Connection:"
Then find the entry that reads "Subnet Mask" and write that down. Should be something like 255.255.255.0
Then find the entry that reads "Default Gateway" and write that down. Should be something like 192.168.1.1
Then find the entry that reads "IPv4 Address" and write that down. Should be something like 192.168.1.2 or higher. This is the IP Address of your PC.

Select an IP Address for your controller that you do not think is in use and is similar to what you wrote down for your PC IP address, like 192.168.1.100 write this down.
In the Command Prompt window type "ping" add a space then type the IP address that you chose above, i.e. 192.168.1.100, then hit enter.
You should see this in the Command Prompt window possibly with different addresses:
"Pinging 192.168.1.100 with 32 bytes of data:
Reply from 192.168.1.2: Destination host unreachable.
Reply from 192.168.1.1: Destination host unreachable.
Reply from 192.168.1.1: Destination host unreachable.
Reply from 192.168.1.1: Destination host unreachable.

Ping statistics for 192.168.1.100:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),"

If you don't receive the above type of response and you receive a response like this:
"Ping statistics for 192.168.1.100:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 3ms, Maximum = 4ms, Average = 3ms"

You will have to change the last number until you do not get a valid response.

Once you have the response that is like the one in bold then you have the settings for you controller. DO NOT USE THE IP ADDRESS FROM YOUR PC this will only cause you much grief.
