General Mach Discussion / Re: Help with verify button

Hi Bob
Thanks for your speedy reply, my problem is not with the column being out of square, ( though it was when I first had the machine).
What happens is I am cutting the outside of a rectangle, the Z axis puts on a 1mm deep cut and goes around the outline, when it comes around to put on the next 1mm cut depth it is about .1mm short of the first position, so when it goes up the right hand side it takes its new 1mm cut, but it also takes a .1mm shave off of the first cut! so making this side smooth. Then when it comes down the left hand side it is .1mm away from the first cut edge hence the steps.
I really need some help with the Verify command, as I am sure it is not working as intended on my machine.

Thanks again
RonC

Hi guys
This is my first post so I hope I get things right
I am a 60 year old newbie, and have just got my mill up and running with Mach3. I have made a few simple parts, still amazed at watching the machine do its own thing! I am having a problem
where it seems that the machine is losing steps in the X direction, IE. one side of the part is smooth and the other side is stepped. It seems that as the programme comes to the point where
the down feed occurs it is short of the X position by a few thou. hence the steps on one side. When I tried using the Verify button all the axis start moving towards the home switches, but as soon as the X axis hits its home switch all the axis reverse for a short distance and then stop, the X & Y axis never reference, and the readings at the bottom of the screen are meaningless.
I have a switch on each axis wired in series acting as home and limit, could this be a problem?
Any help would be much appreciated.
Thanks
RonC
