Basic Information:

Printer Model: Flsun Super racer
MCU / Printerboard: MKS Robin Nano V3

I have had this issue for a while, sometimes it happens after 5minutes, sometimes after 1.5hour, but it always happens,

I followed the step by step guide to install and flash the pi/printer to make sure I did not make any mistakes

Hello @IsacityXD !

Some BG info:

Sounds like EMI issues:

  • Are there high power devices near by: washing machines, ACs, fridges …
  • Do you have a short and high quality USB cable between Klipper host and printer?
  • Are Klipper host and printer on different outlets or, what is way better, on the same one?

No

It is a high quality cable, but it is very long, it came with the printer so I guessed it was good
Are Klipper host and printer on different outlets or, what is way better, on the same one?
On the same
