I can't connect my rs cnc with universal gcode sender.

[Pnrntn]

guys, I ask you for help, I can't connect my rs cnc to universal gcode sander.
I connect the cnc usb to the pc I turn on the cnc and open the program, connect with the com port to baud 115200 but the following word appears in the console section:

**** Connected to COM5 @ 115200 baud ****
 setup: rxfifo size before interrupt = 1

if I try to launch a command it tells me grbl has not finished booting .
if I do the same procedure without turning on the power of the cnc it appears to me the following message to infinity

Did you try in your tft mill -> usb option ... Works for me this way

A direct connection between your pc and GRBL exist only when you have selected on the tft the menu MILL and then USB

Hi! I am also having this problem. Even after the tft mill -> usb option. I've tried on two different PCs as well. Any help would be greatly appreciated!

I got it working, sort of. Once I set it to usb mode I have to reset the esp32. Then it works.

I expect you mean "reset the STM32 (GRBL)" instead of "reset the esp32".

You can do the reset/unlock before pressing mill->USB. The principle is that GRBL must be "IDLE"

Correct, STM32, not esp32, sorry about that.

Even with GRBL reporting IDLE (per the screen, top right), unless I press the reset button on my STM32 after pressing mill->USB and then hitting the connect button in Universal GCode Sender, it will always report as offline, and will report " grbl has not finished booting" for almost any action. Pressing the reset button on the STM32 at this point will always fix it. It's like there's a message that only gets sent at STM32 boot that Universal GCode Sender is looking for.

At reset GRBL sent a message saying GRBL and the version.
It could be that the PC program si waiting for this message.
The same message is sent by GRBL in reply to a "soft request" requested by the PC.
I had expected that the PC program sent such a "soft reset" when it tries to establish the connection.
