我正在组装带有 RAMPS 1.4 屏蔽(板)和 Arduino Mega 的 3D 打印机。我已经组装了结构和电子设备(设置驱动器、放置跳线、连接的步进电机等),并将 Marlin 固件(配置:热敏电阻等)上传到 Arduino Mega。
起初我没有停止测试我的打印机,当时它工作得很好。
今天我添加了三个终点站并再次测试。首先它工作正常,但几分钟后 Proninterface 出现了这个错误:
> Connecting...

**ValueError: Cannot configure port, some setting was wrong. Original message: [Error 31] A device attached to the system is not functioning.**
我尝试移除终端挡块,重新接线,从 RAMPS 屏蔽上移除除电源线以外的所有电缆。它仍然给出了那个错误。尽管当 RAMPS 屏蔽未通电时,Pronterface 连接到 Arduino 板。Arduino 的调节器也在升温。
我需要购买新的 RAMPS 防护罩吗?
