Mach 3 problem

[vmeek]

I think I have more of a mechanical problem than a sofware problem but here goes.
I am using Mach 3 and if I zero my xyz axis and load a cutting g code in my router the code rtuns but the xyz axis does not return to zero.
I have entered 2 different codes and the failure remains the same/not returning to zero.
I think the problem is a weak power supply.
The step motors will stall and the g code count will be off causing the zero point to be off.
Tell me what you think.

You seem to say that you can zero your axis before running your g-code,why would a weak power supply dont make it stall then...
Does it home when you press the home button?
When your motor are not locked-up can you turn the axis freely by hand?
Is there a g-28 towards the end of the code?

Might be this simple.. or not.. but here goes:
Press "ref all home", then zero each axis..
