Hi,
depending on where the 'zero' is that may not be a problem.

If currently the Z axis is 25mm lower than the current Z zero it will show in the Z DRO as -25.
As you jog upwards the Z DRO wil become increasingly more positve through -20, -15, -10, -5,
eventually 0 and then 5, 10 etc.

Soft limits only work when your machine is referenced, also called homed. That requires home switches.

Thanks for the reply. So I guess I'm back to square one. Would setting up soft limits have any affect on my situation?

I thought the way the Z worked is that from it's lowest point and going to it's highest would all be + and page down would be -.

Its common that the machine coordinate of the uppermost Z position is zero. All operations on Z are conducted
at negative Z MACHINE co-ordinates. That is effectively the same as what you have proposed. Its just that at its
lowest it starts a  high negative number and becomes increasingly less negative as it moves upwards.

The DROs however are usually displaying WORK coordinates. Usually you would 'zero' Z at the surface of the material.
Thereafter any positive Z coordinate (remember work coordinate) is above the material and any negative (again
work coordinate) is cutting into the material and you need to concentrate.

Without home switches to reference your machine soft limits are worse than useless, they will fault out all the time
and confuse you. I highly recommend you fit home switches. It was the best and possibly cheapest addition to my mill.

I was using the original Chinese control. It's hard to remember, but I know at one point, when running the demo it cut the material like it should. Something happened and would not plunge into the material and the pattern that it followed didn't appear to follow the roadrunner. I gave up and got a new enclosure with a Gecko G540, mean well 48v 12.5a PSU, rewired the steppers. After all that it's still not working. I can jog XYZ with my keyboard, but can't run a job. I'm baffled. I must be doing something wrong in Mach3. Just can't seem to figure it out. Motors are (X 23 green green 1 1) (Y 45 red green 1 1) (Z 67 red green 1 1). X had to be reversed. Inputs are just the Estop (enabled 1 15 red red). No outputs. Motor tuning was based on Axis calibration. X (400 2800.2 11.6675 3 2) Y (384 2800.2 17.132161 3 2) Z (182.8571429 2800.2 300 3 2). Don't know if I'm missing something. I'm wondering if I may have a defective UC100.

Hi,
when you installed the UC100 did you have to install the communication software that accompanies it?

Hi,
the numbers that you have listed suggests to me that your native units are mm. Would you please confirm that
Machs native units agree.

Yes they are MM.

I used the install from CNCBASIS the sellers of the UC100. Mach3 seems to like it.

I just wrote CNCBASIS asking if the UC100 might be my problem.
