Timer too close on V-Core 3.0 500 with Klipper
I've replaced my Duet board with an Octopus 1.1 and EBB36, plus RatOS, and now in the testing stage. Whenever I run the STEPPER_BUZZ commands, it triggers a timer too close error.
I'm running a Pi4, originally powered by a 3A DC-DC converter off the printer PSU, but even with an official external 3A Pi supply it occurs every time.
Not sure what to check, klippy logs attached in the hope they are some help.
The only things plugged into the Pi 4 are USB-A to USB-C to Octopus, and USB-A to USB-C to EBB36 toolboard. The EBB is powered with 24V from the printer PSU.
Everywhere I google they say it's probably a power issue, but I'm not sure how much more power I can give it. 🙂

Cooling at lower layers reducing hotend temp and triggering fault
Hi! I'm running EVA3 with a 4020 fan, BMG and V6 with Bondtech CHT nozzle, RRF, on my V-Core 500.
I can print at quite fast speeds with this (150mm/s), but I'm having a lot of problems on some models like a Benchy where the nozzle temp drops from 215 to 196 and then triggers a heater fault.
I have PID tuned it, but it doesn't seem like the heater can keep up. I have a silicon sock on but that's apparently not enough.
Is there anything I can do to fix this other than swap the hotend for something else? And if I did how would I know that wouldn't have the same issue?
