I use Windows 10 for development and running my machines, never had a Nano that wouldn't connect.

Sir Arthur Conan Doyle wrote "The Case of the Irrational Nano". Sherlock solved this mystery about 125 years ago. Since Zax is clearly the reincarnation of Dr. Watson he will arrive at the solution just in the nick of time.

When purchasing a new board will I need to program anything onto it or need anything special to get it to work?

Depends on what exactly you buy. If you post a link to any of the items you're looking at we can provide our experience with those products. If you just buy an Arduino nano for instance, you will have to upload firmware to it. If you buy a eleksmaker Mana se 2 axis controller you won't need to do anything other than wire it properly.

Most new Nano (Arduino) boards come with a preprogrammed boot loader. There re  few different flavors with some of the newer units have a version that uses less memory. You can build a ISP loader using an working Arduino and a few jumper wires.

That's a very unusual board but appears to be a standard chipset, what is the problem?

Ah, your board is a dedicated design, looks to me that the arm/arduino/atmega chip is the one on the far left next to the crystal, with no bootloader or a dedicated one it will be a mongrel to program, that unpopulated header on the top might be a way of it may be an expansion port.
Stepper drivers on the right are a4488's, the chip above the usb socket will be a cp2102/pl2303/ftdi for the comms.
Problem is you have no idea what pins this guy is using to talk to the stepper drivers etc, you can replace the entire Pcb without much issue, just depends on things like the power supply in use and connector compatibilty etc.

Zax, Got the engraver from amazon and the installation instructions were hard to follow. when hooking the engraver to the computer and program it turns on but does not connect to your L2 laser program. i thought I followed your steps to load the driver on to the engraver. the engraver has not worked at all.

The first step is loading the Windows device driver (for the CH340), it's in the Help menu.

Then you select the COM port and set baud rate to 115200 and click the lightning bolt to connect.

You should get 2 messages:
Connected COMx @ 115200
Grbl Ready

Do you get these?

If you get the Grbl Ready message you are connected and should be able to control the motors and laser.
