How do you know which baud rate to use? Is that the “Bits per second” in the COM properties port settings (Win 10)?
Continuing the discussion from (Solved) Universal GCode sender not connecting to machine:
In the thread you linked to it states that the baud rate is correct.
The Ardunino/gShield connects at 115200 baud. In the screenshot above, the user would only need to click on the “Machine Control” tab and then click on the $X unlock button or send the $X command to the machine to have it unlocked and ready to start jogging. Better yet they can do an $H or click the $H button in “Machine Control” to have the machine do a Homing sequence, in which the machine will be unlocked and homed at the same time.
Baud rate to connect with the Arduino/G-Code is 115200.
