The picture above was made with the old version of Sineos excellent “Graphstats webpage” tool. You may try the new version, which has much more features [https://klipper.discourse.group/t/rework-of-the-graphstats-webpage](https://klipper.discourse.group/t/rework-of-the-graphstats-webpage). I think you see the error very good here (pink) ![klippy0312_A_log](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/b/1/b1cb29cbab832a3a80cdf9cca46cfa1358cea0d0.png) I spend an hour now to find anything curious in your latest klippy.log. Not much success 😒 `Line 3237: "Timeout with MCU 'MKS_THR' (eventtime=2342.829690)"` is the error before. “Could” point to the CAN bus? You might follow Sineos “Knowledge Base” [https://klipper.discourse.group/t/missed-scheduling-of-next-digital-out-event](https://klipper.discourse.group/t/missed-scheduling-of-next-digital-out-event). First thing I would do “Disk errors / dying SD card” try a new one since it is the easiest and cheapest thing to do. Again, good luck! --- _[View the full topic](https://klipper.discourse.group/t/mcu-mcu-shutdown/20370)._
