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 4.4equal-aqua•16mo ago
Thank 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
