I'm set up in inches, and I would guess that it moved about 10/min. Re: the xml, is it the backupxml in the mach folder?

not the backup, its the one you are using now I need. If you are using the standard Mill profile it will be called Mach3Mill.xml  You may not see the xml extension if you have windows default which hides them so look in C:\Mach3 for a file called Mach3Mill and the icon of it looks like a piece of paper with the globe on it.

here, I think.

Do you have the steps per unit right for the Y and Z, they are different than your X but that may be correct.
Hood

I'm pretty sure I do -- they have a 3/8th screw and the x has a 1/2. And they all worked perfectly this morning.

ok thats fine. I have looked through your xml and so far dont see anything major wrong. If you have seperate drives might be an idea to swap them around and see if the problem follows the drive as I am thinking it sounds like a hradware issue.
Hood

Can I do that by changing the ports and pins settings? It seems strange that 2 of the 3 drives would partially fail at the same moment.

You could change the pins, it would show whether its a software issue if you did that, if the problem followed the pins then its software, if not then hardware. I am off for some sleep (12:30 here ) so hopefully you will get some help from someone else if you cant find the issue.

Thanks, Hood, I will try to figure it out.
All the best, Bob

Did you try changeing the pins? If so, how did it go?
