+# 电机 2020 与底座 3030 直接接触
+
+在上一版轴心整体上移 10 mm 的装配中，取消电机端两块蓝色垫块，将两根电机 2020 型材和两只连接底座的红色角码下移回原始位置。电机、编码器、轴、两只轴承及其固定板、开关示意包络保持上移 10 mm。电机上的四个橙色角码仍固定在电机上，相对电机 2020 沿型材方向移动 10 mm。
+
+## 几何核对
+
+- 两根电机 2020 型材分别直接贴合两根 3030 纵梁；红色角码与两型材为面接触，`检查.txt` 给出相交体积与距离。
+- 四只电机角码与电机后面、各自 2020 型材均为面接触。角码型材侧圆孔在模型中直径 5.5 mm，中心高度分别为 -16.870、36.870 mm，z=10 mm，与 2020 型材侧槽的假定中心线吻合。
+- 按原模型中 110 mm 长的电机 2020 型材示意，孔中心距最近型材端部至少约 18.13 mm，角码最外端距端部约 9.13 mm。实际切长和槽型未确认。
+- 灯光开关横向 2020、A/B 示意孔和角码保持上一版。绿色方盒是估计包络而非真实外壳：开关横梁与包络无相交，但两只开关角码及部分示意螺丝头仍与包络重叠；不能判断实物是否干涉。
+- 上一版假设 A 孔下边缘距孔中心 7 mm，按轴线上移 10 mm 算，该处离横梁顶部约 3 mm；边缘方向和真实轮廓仍未实测。
+
+`Assembly.FCStd` 和 `Assembly.step` 已重开检查。型材槽、滑块螺母和电机角码与型材间的螺丝没有完整建模，接触和几何检查不代表紧固、受力、刚度或完整装配验证。本文件供布局讨论，不是加工图。原装配未覆盖。
