Hello,
My printer stops abruptly at random times 50% to 75% through a print. I cannot recover it through the web or klipperscreen. I need to power cycle. I thought it may be overheating because I transitioned from PLA to ABS recently and the build plate being 100°C so I swapped in a rear cover with perforations and added a larger fan to allow it to ventilate. But it quit again mid-print, and this time with PLA as I was testing the changes. Attached are excerpts from the klippy.log & moonraker.log files. I'm not sure how to read them but I think mcu timeout means a loose cable from umbilical PCB to Raspi4? Has anybody else had a similar problem?
