I have a Zenbot 2424 CNC Router, about 6 months old. I haven't used it much lately, after sitting for about a month, now I'm having an exasperating problem:

If I jog the X axis 10" across the table (I placed marks on the table and aimed for those), the Mach 3 readout only shows about 9.375"

If I try and move only 2.25", the readout shows about 2.125, so it seems to multiply as the distance moved increases.

Anyone have any suggestions? I can only think to re-install Mach3 or get the manufacturer to send me a new control box.

Think in diagnostic? Anyway, you just tell it how far to move, then put in the actual movement amount.

go to the setings tab bottom left corner set steps per unit

should the Z axis dip switches be set as the X,Y ? Because right now I am running my machine 1/2 steps, I asked around and some say 1/8 steps but it just moves so darn slow. What shall I do?
Thank you

One thing I forgot to add is that I am useing 10-2 3/8 acme lead screwws on all axis

Hello
i think your problem is adjust and set the distance in the axis ,you have to :

1- open your mach3 ,
2-click on settings Alt6
3-click on "Set steps per Unit"
4-A window will appear and ask you to put a number of the distance in inchs,for exemple put 10 ,and click on OK.
5-the axis will move and it stop you should Measures the distance ,for exemple you will find 9.39 inch ,a window will appear and you write this value .
finally the program will give you the caluculated steps and the velocity and acceleration,
your axis will move with the new values so you can get a exact distance from your G code
