MCU Error after Update #214

Closed ElektroCoder closed 2 months ago

ElektroCoder commented 2 months ago

After the new Klipper Update today [v0.12.0], I suddenly receive the following error when setting the nozzle temperature to 220°C. Previously, the printer worked absolutely fine:

MCU 'mcu' shutdown: Rescheduled timer in the past This generally occurs when the micro-controller has been requested to step at a rate higher than it is capable of obtaining. 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

Bug in latest klipper, the FIX is 

sudo service klipper stop
cd ~/klipper
git checkout 293858c51fc51c998a046ba12c00da0418fb8403
sudo service klipper start
