Describe your issue:

I’m getting random Timer too close shutdowns.

I previously replaced all my older BTT EBB42 boards with the newer EBB42 Gen2 because I suspected the older boards were causing stability issues related to scheduled OIDs/digital outputs.

However, I’m still occasionally seeing Timer too close.

From what I’ve seen so far, I believe the issue is related to the extruder heater PWM output, but I’m not completely sure.

Could this still be related to OID scheduling or delayed digital output updates? Is there anything specific I should check or any known cause for this type of failure?

I’d really appreciate any help.

I don’t know if this could be related to some delayed macros I use for various checks, or perhaps to the configuration of my outputs or heaters.

Please take a look at my configuration and log. I’m completely lost with this issue.

Even it is zipped?

Git version: '160ea1f-dirty'

This is not a genuine Klipper: 3D Printers with Preinstalled and Modified Klipper Versions and The "dirty" Flag and the Team's Position

You may ask BIQU what is going on.

Can you provide a schematic of your CAN wiring? Include branch lengths and resistor locations,

IMO, 4 TTC’s in a row with no print running = Hardware issue
