I thought I had my machine setup and when I hooked up the software the 1st time there was success...

but to my disappointment I went to the shop last night fired up the pc and my system...but my motors would only go in one direction. this puzzeled me because this is the first time it has happened.

any reason why the motors would not change directions....


also they seem to have a slight bump when I am jogging the motors...

any help.. would be appreciated...
