Connecting A3 to win7 pc

bought for my son a couple of years ago, moving it to the family pc, having trouble connecting through cura and repetier. Have installed the usb serial adapter, and see a usb com4 port, but still not working.

Is there a way to make sure I’m starting from scratch? I read about the ftdi driver shenanigans, and how they were no longer working with cloned chips…is that an issue? I just want get this working. It’ll print from the sub chip, but that’s it.

If some one could point me at a step by step guide I’d appreciate it. Just don’t have the time to research everything from scratch.

Hi,

Please try to update the firmware with the .zip attached. The instructions on how to do it are in the pdf : “AVRUpdateTools userGuide.pdf”
