我用 Noctuas & Buck 转换器替换了我的 ender 3v2 的风扇。在更换过程中，我犯了一个错误并烧毁了主板（将其中一个风扇短路）。我更换了主板，完成了接线。新主板是带有亚马逊TMC 2225 驱动程序的Creality Ender 3 V2 V4.2.7Silent Motherboard 32 位主板。与旧板完全相同，但版本不同4.2.2
打印机可以正常工作，并且使用 marlin 自动归位运行（默认情况下所有选项）。二进制文件名称：Ender-3 V2_32bit_4.2.7_BLTouch_Marlin_2.0.1_V1.1.1_TMC2225
Klipper 版本：FIRMWARE_VERSION:v0.9.1-160-g8a6619d1 FIRMWARE_NAME:Klipper
当打印机运行由 Octoprint 控制的 Klipper 时，步进器不会旋转。当我发送“自动归位”命令时，我可以听到电机通电时发出的轻柔“砰砰”声，它们像婴儿一样旋转（感觉更像是一次振动而不是旋转，就像它们在“尝试”但是没有实际移动的力量）并停留在那里，直到自动归位超时。
我尝试STEPPER_BUZZ STEPPER=stepper_x在 Y 轴上运行和相同，但看起来没有任何事情发生。
我或多或少肯定这是一个软件问题，因为打印机在 Marlin 上工作得很好，但在更换主板之前，我用 Klipper 从来没有遇到过这个问题。
我已经把我的自定义配置放在一边printer.cfg，而是使用我在这里找到的“默认”配置（复制/粘贴在下面）
# This file contains pin mappings for the stock 2020 Creality Ender 3
# V2. To use this config, during "make menuconfig" select the
# STM32F103 with a "28KiB bootloader" and serial (on USART1 PA10/PA9)
# communication.
# If you prefer a direct serial connection, in "make menuconfig"
# select "Enable extra low-level configuration options" and select
# serial (on USART3 PB11/PB10), which is broken out on the 10 pin IDC
# cable used for the LCD module as follows:
# 3: Tx, 4: Rx, 9: GND, 10: VCC
# Flash this firmware by copying "out/klipper.bin" to a SD card and
# turning on the printer with the card inserted. The firmware
# filename must end in ".bin" and must not match the last filename
# that was flashed.
# See docs/Config_Reference.md for a description of parameters.

什么可能导致步进器被 Klipper 卡住，但与 Marlin 一起工作？
我尝试过但没有成功（根据互联网的建议）：
- 解开皮带
!从enable_pin: !PC3配置中删除- 重新构建并刷新固件，而不是重复使用我保留的旧垃圾箱
