BIGTREETECH-OCTOPUS-V1.0 VS katapult

It is strange though that the firmware I've built has a size of 28kb, while the one you can download from the BTT repo is only 23kb. Both can be flashed, but neither of them seems to work.

just checking, have you tried the precompiled firmware from bigtreetech? https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0/tree/master/Firmware

I have a 4.7kΩ pull up resistor soldered between 24VDC and PB7 (probe pin) on my board. This is detailed on page 11 of the user manual here (github).

See the manual for that board here which outlines the different jumper configurations

I followed this wiring pinout and wired my neopixels following this: https://imgur.com/a/TtQbZPe. They are not currently working. The pin referenced on the pinout in the picture references the PB0 pin on the Octopus board as seen here: https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0/blob/master/BIGTREETECH_Octopus_EN_updated_0719.pdf

With care and patience you can do it with a good quality soldering iron. You'll need solder wick to remove the old solder and good flux to fit replacement parts. You can use ordinary electronics grade tin/lead slder for the replacements; it's easier to use than lead-free, which is only mandated for commercial products for sale. As usual for BTT products, the schematic and other documentation are on BigTreeTech's github, https://github.com/bigtreetech/BIGTREETECH-OCTOPUS-V1.0/tree/master/Hardware

I have been using the manual for the M8P and the SB2209. I have also been using the https://github.com/Arksine/katapult with no luck.

When I try to use CanBoot it is opposite: The canbus and can0 works fine WITHOUT pyserial... But as soon as I try to mix canbus-over-usb AND serial-over-usb it all breaks.
