:pushpin: Issue Description

Hello everyone,

I’m experiencing an issue with my Sovol SV06 Ace, and I hope someone can help me find a solution.

When I turn on the printer, I repeatedly get the following error in the Klipper log:

🚨 Invalid lis2dw id (got 4 vs 44).
This is generally indicative of connection problems
(e.g. faulty wiring) or a faulty lis2dw chip.

Additionally, I see this CHOPCONF message:

⚙️ CHOPCONF: 340004c1 toff=1 hstrt=4 hend=9 mres=4(16usteps) intpol=1 dedge=1

:magnifying_glass_tilted_right: What I’ve Checked So Far

:white_check_mark: LIS2DW Accelerometer Connections – I have checked the wiring and everything seems properly connected.
:white_check_mark: Firmware & Configuration – No recent major changes to firmware, but I am unsure if this could be a configuration issue.
:white_check_mark: Power Supply – The board appears to be receiving power correctly.

:red_question_mark: Possible Causes

:small_orange_diamond: Faulty wiring or loose connection – A bad cable or loose connector could be causing communication failures.
:small_orange_diamond: Incorrect I2C/SPI configuration – The wrong pin assignment might be set in printer.cfg.
:small_orange_diamond: Defective LIS2DW chip – If everything else checks out, the accelerometer itself may be faulty.
:small_orange_diamond: Firmware update issue – If the problem appeared after a Klipper update, it could be a software-related bug.

:sos_button: Seeking Help

Has anyone encountered this issue before or knows how to fix it? Any help would be greatly appreciated! :folded_hands:

Thanks in advance!

I got a similar error after replacing the Z Stepper Motors & the case cooling fan.
Have you replaced any parts…??
It went away on it’s own after I re-did the calibrations.
