I've converted my Grizzly G0781 to CNC. Now, I want to control it from my office by means of Bluetooth. I've attempted to set this up using an Arduino UNO and either a RN-42 or HC-06 BT module. My plan is to use gSender on my Windows 11 PC to control the machine replacing the USB cable with BT.

There is a lot of information related to this on the Internet and I have tried a lot of it but no luck. The problem mainly is communicating from my PC to the BT module. The W11 BT settings are confusing and seem to have a mind of their own. gSender connects with the BT com port (com 12) but none of the controls work.

Anyone out there had success with this kind of thing?
