RatRig v4 500mm electronics/controller fan weird behavior
OK the printer is up and running, making very nice prints at pretty quick (if not super fast) speeds. But I've run into a weird problem with the electronics enclosure fan not turning on. I have the single, 180mm fan setup. Forgive me if this has been solved already, I did look around on this channel, but haven't been able to find a solution. Thanks.
The fan is (was) wired up as per the build manual on PD12 (Octopus v1.1). It worked fine at first but stopped working after a few 10 hour prints. The fan works when I apply 24v from an external source.
The ratOS dashboard shows the controller fan (PD12) as running, but it doesn't turn....
Beacon calibration failing during comissioning
I'm just assembling my first RatRig printer (first DIY, but fifth printer overall). I'm no stranger to DIY and the build went smoothly. My printer has passed virtually every commissioning step but one:
BEACON_RATOS_CALIBRATE
I've read a lot here about causes of this error, so I've tightened every bolt on the printer, I've tried hot-tightening the nozzle, changed the nozzle - everything I can think of. I've checked there's no play in the print head, my belts are evenly tensioned, but I always end up with the same error.
...Solution:
Figured it out, there was a tiny bit of "stuff" (not sure what it was) stuck to the build plate and that was throwing off the beacon. Scraped it off and passed with flying colors!
Layer shifting during Skew Calibration Print - VC4 400mm IDEX
Getting layer shifts in prints. Could it be belt tension related? I'm not used to using resonance graphs to tension belts.
Cat pissed on my printer. Need new parts. What do you recommend?
Title says it all, printer got fried as the cat pissed on the rpi 4 and SKR PRO V1.2. Everything else looks fine, but need to replace those two, so why not upgrade!
What is the go to for the SKR Pro replacement?
I have had a big hiatus from the RatRig discord for a long time, so out of touch with the new parts available

MCU unable to connect
I was mounting a spring to get strength to the umbilical cord, it was just a small part to understand how better it was getting.
But I endup assemble it all, and when I was getting close to the toodhead, the fans turn on.
I turn off the printer and when I turn it on I got the "MCU 'TOOLBOARD T1' unable to connect" error (first picture error on the touchscreen).
I search for any disconnect cable (as happened in past) but I couldn't find any. I turn a few off and connect it again.
Then I got a different error "MCU 'MCU' unable to connect" (second picture error on the touchscreen), and it stays like that....
Am I screwed?
I was rebuilding my toolhead... went to heat up the hotend and noticed it wasn't heating up, after taking the hotend off, i noticed the heater wires have come off the ceramic of the Phaetus Rapido.. (not sure if it's the 2, it came with my VC3.1 kit about 3 years ago)... what can i do? am i screwed, or can i fix it myself?
