Z轴不向上移动

我即将完成 i3 MK2 克隆的构建,并且遇到了 Z 轴电机的问题。具体来说,Z 轴将向下移动(并触发限位器)但如果我尝试向上移动它只会发出快速的噪音。

M119显示所有限位器打开。最小软件停止当前被禁用,因为我尝试设置打印机。使用 Marlin 1.1.3 和 RAMPS 1.4。两个电机都在转动,我什至解开了整个 X 轴托架。

附加测试:反转 z 轴电机线,它们只会上升。在软件中反转电机方向,它们也只会上升。

有什么建议吗?我确实做了一些搜索,但没有解决问题。

这听起来类似于Prusa i3 Z 轴只会下降(即使是向上命令),我的 Prusa i3 的 z 轴只会上升。请检查这些问题的答案。

问题的常见原因是您需要:

  • 安装/配置终点挡块,以及;
  • 归位 Z 轴。

你说你已经安装了广告配置了终点站。不过,你已经回家了吗?

但是,请先检查您的接线,因为这可能只是连接松动或错位的简单情况。

另外,还有一些需要考虑的事情,如果您的步进器发出咕噜声,并试图移动但不能移动,那么您的步进驱动器可能没有提供足够的电流,或者可能太多。请参阅挤出机步进电机问题的回答,可能有什么问题? .是的,答案是挤出机,但所有步进驱动器都可能遭受相同的错误配置。

感谢绿网。是的,我已经安装了系统。当我尝试移动 Proterface 时,它​​甚至会在 z 轴上计算 mm,但它并没有实际移动。当我在软件中反转 z 轴方向时,小车确实向上移动,但不会向下移动;所以这似乎不是一个太小的当前问题。

如果马车朝一个方向移动但不是另一个方向,对我来说似乎是步进驱动器的问题。或者可能是电气接触问题,因为步进驱动器每个都有一个引脚(引脚 DIR)来控制步进器的方向。

您是否尝试过更改 RAMPS 1.4 上的驱动程序?我建议您暂时使用您知道功能的轴更换步进驱动器。

谢谢,阿克塞尔。当然已经尝试过交换驱动程序。我开始怀疑它可能很容易成为 RAMPS。

更新:原来是一个有问题的坡道。更换了卡并没有进行任何更改; z 轴现在运行正常。谢谢大家。
