Klipper won't start.
Please, I need some help. The Octopus PRO Manual, and dozens of on-line images of Octopus PRO wiring make no mention of Jumper J68 (V_BUS/5V). This is my first 3D printer, but I have been building electronics, and writing computer code for about 50 years. I've built a Standard Rat Rig V-Core 3 500. My problem is that Klipper won't start. I have a Raspberry Pi 3 B+ connected to the Octopus via USB-C. There are several LEDs illuminated on the Octopus, including green motor power and a rapidly flashing red "STATUS" LED. All six motors appear to be energized. I have a Windows 10 laptop that seems to be communicating very well with RatOS via WiFi. Since I had no knowledge of this J68 (V_BUS/5V) jumper, have I damaged the Octopus by powering it with both 5V and 24V?

4.4 MCU POWER JUMPER in the manual (https://raw.githubusercontent.com/bigtreetech/BIGTREETECH-OCTOPUS-Pro/master/BTT_Octopus_pro_EN.pdf)
you can see all the pin names in https://raw.githubusercontent.com/bigtreetech/BIGTREETECH-OCTOPUS-Pro/master/Hardware/BIGTREETECH%20Octopus%20Pro%20-%20PIN.pdf
you can see that J68 is labelled there and it is the same jumper the manual is talking about in section 4.4Thank you, blacksmithforlife us. At 74 years of age, I think dementia is starting to set in. My sincere apologies for taking your time.
No worries, I am guilty as anyone of missing stuff in a manual. Glad I could help! Come on back if you have more issues, this is a pretty friendly place
