I can now direct serial communication to the assigned IP address and it will be passed on to whatever device I connect to the WIZ750SR. This is all explained in the Getting Started Guide.

I did another search for the device with the config tool and my module was found. I put my PC back on my network and plugged the WIZ750SR module into my switch. I then gave the module a static IP that was compatible with my network's subnet. After a short period, the update was successful and the new firmware version displayed in the Device Info section. I clicked the "Upload" button and selected the firmware bin file I downloaded previously. Once I clicked on it, the settings were displayed. After launching the config tool, I clicked "Search" and the module showed in the list on the the left side of the window. I then changed my PC's IP to 192.168.11.3 and connected an Ethernet cable between the WIZ750SR module and my PC. I downloaded the latest firmware for the WIZ750SR module and uploaded it using the WIZnet S2E Configuration Tool. This allows me to upload firmware and breakout the interface. To start, I plugged my WIZ750SR module into the WIZ750SR-EVB board. the WIZ750SR and CNC Shield combo will work with many other devices such as laser cutters/engravers, vinyl cutters, automated robotics projects and more!

I used many resources to complete the entire upgrade, so I will include links to them. As a bonus, I will share my configuration settings and some of the steps I took to integrate the entire assembly into my inexpensive CNC mill. In this project, my focus is to show you how to connect the WIZ750SR to the CNC Shield device to make it network connected. This is a great step in enhancing the collaborative and open maker revolution. The addition of the WIZ750SR module network-enables the machine, allowing me to control it from all of my workstations. I operate a maker space in my garage and have several workstations to design and create stuff.

One feature the CNC Shield lacks is network connectivity. I like to use for controlling my CNC mill to create prototype PCBs. This shield allows you to control NEMA steppers with an Arduino Uno and provides interoperability with a multitude of open-source and/or low cost software using GRBL. The CNC Shield offers a low cost option for the DIY community to control machinery.
