Maybe then we should just call it what is... It's out there in the wild so we can't just ignore it. The door feature saves people in numerous...
At least you got the brownout solved. I was going to mention trying a different cable but assumed you were using the one that comes with it.
See the brownout detector triggering? It's causing the board to reboot.
You should be able to. Basically all core ESP32 functionality + Grbl should be running. The 24V power supply input powers the stepper drivers /...
The USB port powers just the ESP32 chip.
do you have access to a multimeter? you could try verifying the polarity / voltage coming out of the power supply on the DC side. I don't know...
I'm going to guess you've got the power wires reversed.
so I tried again on the zotac pi-225 (it's tiny dual core intel celeron with usb-c) and esptool.py is reseting the port fine. There's something...

Thanks for sharing this. I followed this procedure for my BlackBox X32 and (same) Huanyang VFD. Overall, working just fine. One minor...
at least from my pi, it is not a "card not present" transaction, LOL. I haven't tried to connect locally from my mac. Similar, but different...
hmm, esptool refused to do anything useful until I held down that "pin".
Ah, thanks Peter! I don't use OpenBuilds-CONTROL and completely forgot it manages all of this. So, let's call this the "old school" approach :)
For those planning to do custom firmware on their BlackBox X32 or just want to have the factory shipped firmware as the ultimate backup, here is...
