odd behavior involving tool head fans
I'm going through the commissioning process, and the first issue I came across was that my part cooling fan was stuck at Mach 12. After days of trial and error, I randomly stumbled on the idea to move the PWM wire from the tool board to the control board... and weirdly, it worked? (I have no idea why.) At that point, I just accepted it and moved on. Then I noticed similar behavior with the tool head cooling fan—not operating at all. So I went back into the config and started trying to make sense of it. That’s when I noticed the fan wasn’t mapped properly, which would explain why the PWM signal was coming from the control board instead of the tool board. i have no idea how to write in to the config to designate i want the 12v signal to come from the toolboard instead of wiring back to the control board. any help would be amazing

🛑 V-Core Z Homing Crash | “Shutdown due to X and Y must be homed before homing Z” Error on RatOS /
Hey all,
I’m having an issue with my V-Core running RatOS + Klipper. When I home the printer with the homing button, XY homes perfectly. But right before Z starts, the plate drops ~5mm and the system immediately shuts down. Console Output: 
Shutdown due to X and Y must be homed before homing Z  
Once the underlying issue is corrected, use the  
"FIRMWARE_RESTART" command to reset the firmware, reload the  
config, and restart the host software.  
Printer is shutdown

config, and restart the host software.  
Printer is shutdown
This repeats even though XY was clearly homed first. No clue why it thinks otherwise. --- Any idea what’s causing this or how to fix it?
Appreciate any help.

RatOs operating system
I've built my Rig. and had an issue with the operating system. so I re-flashed the sd card with RatOS. went through the installation and update process. Do I need to re-flash the board? I have no idea what im doing. the printer is just sitting here with the part cooler running at 100 percent
