Hi, Mike

Under Config, Homes & Llimits, There is a "Reversed" coll-um, Change the Z "X" mark to "Checked", That should do it.

Thanks, Chip

Brett: That fixed that problem so guess what I owe you a big thanks.  I'm so happy I found this forum Its a great place for newbies like me.  LOL   I think the motors are turning pretty nice and I just need to learn how to use the mach 3 ,  such as figuring out how to find a zero for xyz and of course run the g codes.  I'm using bobcad cam version 19 which I have never been very happy with but I'm stuck with it for now.

I really thank you a lot! I been working on these problems for two days now trying to get it up and running again.  Thanks again Brett.

Mike
