Issue with SKR Pico v1.0 / Invalid oid type & Timer too close

General Discussion

Basic Information:

MCU / Printerboard: SKR Pico v1.0 (UART or USB) + SKR MINI E3 V3 (USB) + BTT Eddy (USB)
Host / SBC: BTT PI v1.2, tested on BTT image V2.3.4 and v3.0
klippy_usb.log: SKR Pico connected via USB and installed on top of RPI. Cooler blowing on Pico. BTT PI using image V2.3.4 with klipper preinstalled
klippy_uart.zip (1.3 MB)
klippy_uart.log : SKR Pico connected via UART and installed on top of RPI. Cooler blowing on Pico. BTT PI using image V3.0 with klipper preinstalled
klippy_uart+fan.zip (4.3 MB)
klippy_uart+fan.log : SKR Pico via UART and installed next to RPI. Added 3rd cooler blowing on RPI. BTT PI using image V3.0 with klipper preinstalled

Hello all,

I have an issue with configuration described above.
Pico gets disconnected when I`m doing such steps:

G28
_CLIENT_LINEAR_MOVE Z=200 F=600 ABSOLUTE=1
M84
G28
G29

It happens not all the time, but on 3rd-4th try.

Eddy configured to do mesh 200x200 specially to make load on RPI CPU, as I thought about shutting down after 54 degrees.
First issue randomly happened when Pico was connected by USB: Timeout with MCU ‘pico’ . RPI was connected to power-adapter via 24V
I tried to switch to UART: MCU ‘pico’ shutdown: Invalid oid type. RPI takes power from UART / PICO
Last try separated PICO from RPI and added 3rd cooler: MCU ‘pico’ shutdown: Timer too close. RPI takes power from UART / PICO and cable changed.

I measured Voltage on power-source - 24V no matter what I`m doing: heating the bed, nozzle and homing at the same time.

Please give an advice what else to check.

Thank you in advance,

Unfortunately, it is not clear what is happening. All looks like some hardware issues with the Pico.

Could be an effect of the excessive mesh.

seems so…
I changed RPI, changed Flash and newly installed os, changed screen, gave power from laboratory source. Only left is Pico…
Will try to move z-motors from Pico to SKR mini E3 V3 to see if it will help. All devices are out of the box(

Switched to katapult and saw how can0 appears/disappears.
Issue with controller.

Thanks for advice about possible hardware issue!
