### Basic Information: Printer Model: Ender 3 v2 MCU / Printerboard: 4.2.7 Host / SBC Raspberry Pi 4 klippy.log [logs-20250623-074039.zip](https://klipper.discourse.group/uploads/short-url/p9HOIsKv3legPvi6Qnc5531MOTF.zip) (22 Bytes) ### Describe your issue: I have started having issues with prints failing at random times, I think its related to bed temperature not being maintained. As a test i set the bed temp to 60 and it remained at that temp between the following times 07:17:11 07:25:11 Not sure what else to check and other tests which can be used to diagnose the issue.

mmmhh, bobster316 said > [@bobster316](#): > > As a test i set the bed temp to 60 and it remained at that temp between the following times Don’t know ![bed](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/3/b/3b7399320dde9393ad3a5040bc52a670eb9277c8.png) @bobster316 Was it 60°C or 55°C? I think you may have problems with your connection of the host to the PC. ---

As indicated by @EddyMI3D and according to the log: - Bed temperature is according to the set target and controlled nicely. - No heating-related errors in the log. - Two instances of a [Timeout with MCU / Lost communication with MCU](https://klipper.discourse.group/t/timeout-with-mcu-lost-communication-with-mcu/6639/1) error. ---
