I am getting the above error but it shows it is connected but it gets commands waiting and the "Communication timeout - reset send buffer block" error.
I am on windows 11 and have multiple serial connections with other devices, Multiple lasers and a CNC router and no problems with their connections. I have made sure which port it is and changed which hub and even which usb port on the computer. I have played with the baud rate, currently at 115200.
