Everything that I test will either be on a Windows7 - Ultimate (64-bit) or an XP Professional machine. I can't guarantee that the drivers loaded onto my machine for the COM port are the correct drivers. But, they are the drivers that Microsoft Windows 7 THOUGHT were the right drivers and they at least allow me to cut. When I first loaded the software the driver, for whatever reason, failed to install correctly.
The name of the driver on my machine is Silicon Labs CP210x USB to UART Bridge (COM3)
The settings are the defaults.
When we click the Advanced Button, we get some more information about the driver settings. Again, these are the default settings.
The third tab in this dialog box reveals the date of the driver, which in my case is 7/21/2010.
But, selecting the driver details reveals the most useful information for those whose drivers have failed to load correctly. If gives us the files and the locations of those files. If your is failing, you might want to check for these files.
This tab isn't all that interesting. But in the interest of showing all the tabs, it's included.
And, the same is true of the last tab. It may be that you might want to uncheck the auto power off. But, only if you suspect it's giving you problems.
HOW MINE FINALLY LOADED
I could not cut when I first installed the software. I knew not to connect the cutter before installing it. So, that wasn't the issue. And, I tried, several times, to unplug and plug in the USB cable without success.
So, I went to the System Device Manager and found that the device driver WAS loaded. But, at the time it was 'not working correctly' for whatever reason. It will be found under "Ports (COM & LPT)
I made sure the eCraftShop pro was closed and the eCraft was turned off. Then I deleted the entry. I cannot remember if I rebooted or not. But, once its was deleted I attached the USB cable and turned on the eCraft. At that point, Windows 7 went searching for the driver for the eCraft and installed it correctly.
Now, I THINK this is the correct driver. But, I have not seen any other machines and Windows could have found a close match. I am having some problems cutting SVG files. And, it's possible that it's a driver issue.
I'm a software developer. I don't claim to be a hardware guru. So, take this post with that in mind. It's at lease worth a try for you.
