STM32 Blackpill? about iosender HOT 4 CLOSED

It should work provided that the board runs Grbl compatible code and enables a USB CDC stack for communication.

You may try grblHAL - if that works then uCNC does not enable a USB CDC stack or fails to do so.

I used a USB to USB C cable to program the board, by "DFU". I haven't used the Serial cable , I'll get one today and try that.

Once I've uploaded the code and give power externally to the board (or still via the USB-C), the Diode doesn't blink every second.
The Power LED shines, but the PC13 Builtin LED Doesn't.

Update:

OK So here's the thing, I tested uploading just the basic LED code onto the chip to see if it works, and it didn't.

I Erased All memory from the chip using STLink Utility and STLink V2 Board. And then the LED Sketch worked, I tried uploading the uCNC Code right after. Didn't light up again.

I Erased All memory again, uploaded uCNC to the Clean memory and then everything worked perfectly.

This may be a normal STM32 thing or a counterfeit thing that I just wasn't aware of. (Also the board came locked in RDP_1 for some reason so definitely a sketchy board with all these things combined)

Conclusion:
Reuploading isn't a thing on this board, only uploading the code after erasing all memory makes the code actually run.

Anyway, my problems are resolved, the board is recognized via my USB-C Cable, and works with ioSender.

Does your "Blackpill" have a real STM chip on it? Many of the STM32 parts have been cloned and unscrupulous vendors use remarked clones to get a better price. The STM32F1xx line has at least 8 known knockoffs. The GD line is a pretty good clone, others are not so good, though. I believe the F4xx series has a couple. It's one of the reasons I did not use STM parts for my BOBs. You just never know what you are going to get.

The chip is either mislabeled after beeing recycled or a clone since the device id does not match the labeling, also the ST logo is missing.
