General Discussion

Basic Information:

Printer Model: fysetc voron 2.4 kit
MCU / Printerboard: Fysetc spider with a SB CAM hotend board
Host / SBC Raspberry pi 4
klippy.log
klippy.zip (1.7 MB)

Describe your issue:

…printer has been working fine, I haven’t made any changes or updates recently, today I started a print and part way through the print I got an error telling me that klipper got disconnected.

now I’m dead in the water, mainsail shows mcu unable to connect, and if I try to restart firmware, it just says
“Printer is not ready
The klippy host software is attempting to connect. Please
retry in a few moments.”

I’m kind of at a loss.

Have you checked the connection/wiring from the SBC to the MCU?

not yet, I was putting off flipping the printer to check.
it didn’t seem likely that something would have become disconnected mid print.

I just checked all the connections seem correct, nothing seems to be out of place, still no dice.
