I don't have the f103c8t6 board to test anymore
from ucnc.
How did you compiled it?
Arduino IDE, makefile or PlatformIO or used the precompiled file?
I don't have my board with me right now but I will confirm it in couple of hours.
By the way... have you tried grounding PIN B5? That's the Emergency stop. If left unconnected it will lock the firmware for safety reasons. That can be modified via config file.

The problem is that the usb is not correctly recognized, is your crystal 25MHZ? Tried the precompiled v1.4.2 uCNC-USB-STM32F4-Blackpill.bin you posted in git, and PB5 grounded, and compiled with vscode, and enabled DISABLE_ALL_CONTROLS
from ucnc.
In about an hour I'll be able to test it and let you know. I think it is 25Mhz.

I've just uploaded the bin that is precompiled in github and it's working. Even without Pin B5 grounded. The led (PC13) should be blinking at a 1sec rate (this is a visual hint that the firmware is running).
I used st-link to upload the firmware. What did you use?
Here is a pic. I confirm it's a 401cdu6 at 25mhz
Also a print of a status query ?
and reply by the board on a terminal
from ucnc.
Also tried with STM32CubeProgrammer in DFU mode and again all worked.
from ucnc.
The led of PC13 is only on, not flashing, I try to burn the grblhal version again, his usb virtual serial port works fine, you have noticed that your chip is CDU6 instead of CCU6, I don't know what will be the difference, just flash capacity
?

I bought a f103c8t6 today, it's on the way, it will arrive the day after tomorrow
from ucnc.
what did you use to upload the firmware?
If the led is not blinking that is an indication that the firmware is not running somehow.

Tried both with usb dfu and serial port with STM32CubeProgrammer

I have a little knowledge of microcontrollers, the PC13 LED is on means it is indeed running

In your program, does the PC13 LED light flash as long as it is plugged in without any communication?
from ucnc.
The PC13 blinks because there is an internal function that runs every millisecond. Among other things (depending on the board) it makes a status LED blink every second.
Can you try the alternative method via Arduino IDE?
from ucnc.
If you don't have the STM32duino installed for Arduino IDE please read the wiki tutorial

Thanks, I will try again when my C8T6 arrives

Hello, after experiments, the firmware burning of the F103c8t6 version I purchased works normally
from ucnc.
I'll try him on my machine and see how he performs

Thanks let me know if you find something off or bugged and I'll try to fix it ASAP.
