Octopus V1.1 won't connect via USB
I'm just building my first Rat Rig (a Vcore 4).
My problem is: the board just won't show up as a USB device (it's still outside of the printer, without drivers and without anything connected to it).
dmesg output always is like:
So far I have tried:
- Different USB cables (long, short, USB 2, USB 3)
- Different USB ports on the Pi
- Connecting it to my notebook
- Powering it via USB or via 24V (lab power supply)
- Pressing the reset button on the Octopus for a long time or twice or more in quick succession
- Entering DFU mode via BOOT0 jumper and also in addition with BOOT1 tied to GND
- Flashing via SD card: the LED blinks and it renames the file from firmware.bin to FIRMWARE.CUR
- Flashing via debugger (ST-Link / Black Magic Probe). The MCU is detected correctly, erasing and flashing seem to work fine as well
- Reinstalled the BTT bootloader, then flashed Klipper again
Do you have any advice? Something I maybe have overlooked, tips that I might have missed?
In my desperation, I have already ordered a new board, hopefully arriving tomorrow. But I'd like it much better, if I could get the one that was part of the printer kit to work
