Mach 3 axis reverses by itself??

[Barefootboy4]

What will cause the direction of all three axis to reverse direction?? The machine and program will run fine all day but when I close out the program and come back the next day the now Pos (+) direction of all 3 axis are now Neg (-). I have to go into ports and pins to reverse direction and the next day it reverts back. I'm sure it's a simple thing but I have no idea.
Any ideas out there??
Thanks

first check to make sure that you have administrative rights on the machine. If you change the directions and do not have the rights to copy the changes to the file, then, well... it wont.

Right click on the c:\mach3 director left click on properties. See if the "READ ONLY" field is checked. If so uncheck it.

After you fire it up and make sure its all moving the right way, click on config then go all the way down in the drop down box and click SAVE STETTINGS

Close, re open and see if the changes stick.

just a couple ideas

you are remembering to reference all your axis to home each time you turn on mach3 right?

Nope!! Did not realize I need to do that! I just did it the first time I set up the machine and I'm doen with it. Now that makes sense!
