MACH3 步进电机太慢，设置问题？
我将Mach3的内核速度设成35000Hz，按说明书上讲，这是MACH每秒能输出的脉冲个数。但我将电机调试中的速度设成最大值，用示波器测的结果只有500Hz，这导致我的步进电机转动非常慢，我的步进电机是每圈800个脉冲，脉冲的频率希望是2000到4000Hz之间，500Hz显然太慢了，是不是我什么地方设置有问题？请指教，多谢。 http://www.ourdev.cn/bbs/bbs_content.jsp?bbs_sn=1857062&bbs_page_no=2&bbs_id=1027 回复【1楼】JinBao-----------------------------------------------------------------------

多谢两位。
这个问题已解决。原因是我用笔记本，试了JinBao提供的下面的信息，将笔记本设成标准PC后，电机速度曾变得正常一次，但重起笔记本后，仍有相同问题。在artSoft的讨论区也看到了相同的问题，用上面的方法解决了，但在我的机器上不行。最后，我只能改到我的desktop机上。好象是正常了。我的桌面PC是3GHz CPU，不必改动设置，装上直接用。
