Bed Heater Failing on long heating segments
Been printing at 50-80 degree bed temperatures no problem. Just recently wanted to start doing some ASA and went to heat my bed up to 105.
Started the first print, got a heater error. Looks like at about 100 degrees it stopped getting hotter. Restarted the printer, and with the temperature already fairly high I turned it on again. It got to 103 before it randomly stopped heating again. One more time, starting at 90, and it was able to get to 105 and hold it no problem.
The best I can tell is that something is going wrong with extended 100% power input. That sounds like issues with the power being provided, but I'm not sure how to test that. I have a multimeter and all the tools, I just don't want to probe around without knowing exactly what I should probe....
Gaps on Pause Resume
I am looking for guidance on how to fix a small gap that happens when I pause and resume my printer after filament runout.
Every time I resume with new filament the print shows a clear gap at the resume
What setting or adjustment can I make to fix this ?...
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....
