Octopus 1.1 Firmware Issues + Magic Smoke
Howdy folks, am on the last legs of building my VC4 400(the scary side when you plug it in for the first time).
My Octopus board originally successfully connected to the Pi before I did the electronics installation (registered in DFU mode in the configurator).
Throughout the installation, I followed the instructions to the best of my ability but ran into two separate issues:
1. The power connections (power from the Octopus to power the pi) for the raspberry pi resulted in a cooked pi , if you will. this may be related to my second issue
2. In the instructions for installing the fan jumpers in the electronics section (step 68 of the manual), it had you install the middle jumper. I had accidentally also left the left jumper on, which caused a bout of magic smoke to appear when I first powered the board from the wall. All other jumpers were removed except for the stepper motor jumpers and the power jumper that allows you to power the board via USB.
Now, I can not get any information from the board. It turns on successfully with the green light next to the power jumper and also registers an SD card with the blue light. I have attempted to flash firmware or detect the board via DFU mode in the configurator, as well as tried to flash firmware manually via SD card. There are no results in detecting the board via the configurator.
I am wondering if I've cooked the board completely and need to get a new one, or if there are other alternatives I can try before then.
Help is appreciated,
Zeke

sounds like one or more components are dead - get a new board
Yea, was afraid of that. Thanks
In manual small mistake https://ratrig.dozuki.com/Guide/12.+Electronics/250?lang=en#s2537 - suggest connect 5v and 5v to pi, without GND(if BTT octopus ). Right connection on screenshot

This guide is still in progress, as more detailed instructions on how to prepare all wires will be added in the next few days.
Gocha gocha, thanks!

This is not the same port as the guide instructions the raspberry power to be connected
It's the one right after the stepper drivers
Not sure where this image is from, but it's wrong it's not the octopus V1.1

Oh this is the octopus pro
I didn't realize you were talking about the octopus v1.0 pro
The vc4 comes with the octopus V1.1
i send links to 1.0 and 1.1

What I mean is, this is the octopus V1.1 PRO
It's a bit different from the standard octopus V1.1
Do you have the octopus v1.1 or the octopus V1.1PRO ?
V1.1, I actually just finished setting up
My mistake.sry. I see
No worries, it can be confusing
I probed the pins with a multi meter. this image was correct
thanks for the help, folks
Could it have been a miss wiring on the pi wires?
potentially. I also had the jumper for the power pin on the V1.1, which could have caused errors
running into an alternate error now during bootup for the initial beacon calibration, saying "No beacon model loaded"
The middle jumper shouldn't have effect on it
Run the BEACON_INITIAL_CALIBRATION
Not sure then... It's fixed now lol so it is what it is. might have been some other error without realizing it, I replaced the whole board and checked all the wiring, so something might have changed
yea that's running into the "no beacon model loaded" error
Try BEACON_RATOS_CALIBRATION
roger
restarted the machine, the error was that there was no restart following the "SET_CENTER_KINEMATIC_POSITION" command which I used to make sure that all the steppers were plugged in correctly
so the original command works
thanks for the help
Oh, yah, you must always restart after running kinematic position
yea that makes sense. I'm very new to all things klipper, so it's been a learning curve😂
