Catalyst 3.0: MCU

[7kgspool]

Basic Information:

Printer Model: voron 0.2 Pro R1 from a Fysetc kit
MCU / Printerboard: Catalyst v1.0 with v0 Head Hub
klippy (1).log (369.0 KB)

The printer was working in this setup for 100h, then i started it with the Head Hub unplugged. As i got a an error (ADC out of range) i plugged it in.
Since then i get the following error message and im no longer ably to ssh into the printer:

According to Timeout with MCU / Lost communication with MCU it may be missing power or bad connection.
The LEDs for 24V, and at the step downs of 5V and 3.3V are on.
Behaviour does not change when started without the head hub connected.

how can i go on with debugging? I’m a hardcore duet user taking my first steps into the klipper world.

Thanks

Did you plug it in while it was powered?
If so, that may have damaged the mainboard.

[7kgspool]

Yes, i did.

What part could have been damaged in this event?

Now i get this error Message, the small Display in the front now works:

There is a USB C right next to the mcu. Any ways to diagnose it via this port?
How to interpet these logs? I cant ssh into my pi to follow this procedure from
klipper3d . org → extracting-information-from-the-klippylog-file (and i cant paste the link?!)

I’m unsure, if I understand understand you right.

This is your printerboard?

If yes, you could answer my questions. If no, forget my post

@7kgspool

The printer was working in this setup for 100h, then i started it with the Head Hub unplugged.

Why?

@7kgspool

As i got a an error (ADC out of range) i plugged it in.

Which connector did you plug in under power in above image?

I guess “HOTEND”.

Good luck, hcet14

@admins Right category?

[7kgspool]

hi hcet14,

Why?
hmm, being dumb is maybe the most approriate answer xD had the printhead out for maintenance and wanted to rush wifi setup. It stated an error (i guess “adc out of range” as it missed its hotend thermistor. So i quickly connected it.

Exactly, i plugged in the connector “HOTEND”

Although the hotend has been touched the log shows issues with the mcu_temp and chamber:

Bed and extruder look more valid…

Moved the thread into the right category.

Hi LifeOfBrian,

thanks for moving!
Over all, all the analog pins pins look floating.

The STM32F401RCT6 used as MCU has one internal ADC, serving for up to 16 Channels; i guess, I might just killed the ADC?
