EBB42 v1.2 via DFU
I am trying to configure an Octopus 11 with an EBB42 v1.2 toolboard but cannot seem to get the toolboard into DFU mode. I have connected the toolboard to the Pi via USB. I have inserted the jumber on the VBUS pins. I have rebooted the Pi several times. There are no illuminated LEDs on the toolboard. The RatOS configurator stays at "Waiting for DFU. Am I missing something? Do I have a bad toolboard?

I just re-ran the setup wizzard and it's requiring me to flash the board. I cannot get the control board into DFU mode either. When I ran the setup wizzard the first time, it detected and updated/flashed the board automatically. This time, the wizzard is requiring DFU mode which I cannot seem to enable?
I don't remember exactly but from the top of my head you connect the board, then press and hold the boot button on the board, while pressing and releasing the reset button on the board then releasing the boot. I can be wrong though so if it doesn't work, google is your friend
Yeah, I tried that repeatedly. I think there’s something else going on as the status lights on the control board do not illuminate.
At least the green LED must be on. If not, there is no +5V from USB.
Thank you for that. I have installed the VBUS jumper but, still no status LEDs. I suppose I could try a different USB cable but, I suspect something else is wrong? Not sure what that could be. The Pi is powered through a buck converter. Could that be a reason?
Unplug all cables from the EBB. Only use the USB-C for power. If the PI is running, it should not be the buck converter. Try a 5V USB charger , from your cellphone .
I am now powering the Pi with a dedicated power supply and not the buck converter. The VBUS jumper is in place. I have tried multiple USB cables between the Pi and the tool board. I have also tried multiple cables between the tool board and my computer. The tool board status lights do not illuminate. I think I may have a bad tool board?
Does anyone know if RatOS supports the EBB 42 WITH Max? It's the only version offered on Amazon. The non-max verison which I currently have is not available.
It does support EBB42 with Max, but that feature should not be used as people had issues with it in the past.
Good to know. Thank you.
Just a note the power pins on the Molex are a little flakey, I had to cable tie the connector. I just ordered a spare, as I thought it had failed., but it was the connector.
I’m powering through usb?
So, I received a replacement board today. On this replacement board, I inserted the jumper on the VBUS pins and plugged the board into my computer. Same as the other board: status lights do not illuminate? What gives? What else could be the issue? Surely I don’t have two bad boards?
Have you tried the PWR/CAN 24v Molex connection just to confirm it powers up?
No, I have not. I’m on my second board with the same issue.
I would give it a go, to narrow it down two, the 2 I've had worked fine once I got them programmed. I used the 24v on the Molex first then went to USB DUF, 2nd did not program first time using the ROS configuration tool. as the SKRat was already programmed.
Did you first try powering the boards via usb?
Okay, so I plugged a USB power supply into the 2nd board and it powered up (status lights illuminated). Now I am questioning: Does the board have to be powered via CANBUS and connected to the pi via usb to control the tool board? I admit, I may misunderstand how the board is supposed to be connected and powered. I thought, based on reading the setup instructions for RatOS that everything wouild be handled via USB and not CANBUS. Power, programing and control all via USB. Is this incorrect?
Morning, USB-C connection as I understand it is only the communication side once in use, the hot end and stepper needs more current /voltage than the USB-C can supply. My V-Core pro is powered by a 24v supply, so I use that for EBB42 , stepper motor, hot end etc. connected via the Vin on the CAN Molex. So I power the whole board via the Molex. The CANBUS +/- are not used and in my case left open.
