No, I just typed g00 x4 and the DRO displays 4.000 but it moved about 2 feet.

Ok then your calculations for steps per unit are wrong.

You dont have any home switches enabled so how are you referencing the machine? You need to reference before you can use SoftLimits as Mach needs to know where it is. You can reference without having switches, I think Rich wrote a doc on how to do it so I wont waste time retyping, you should find it in the member doc area.

Yes Motor tuning to enter the steps per unit. If you want a quick and dirty way of getting the steps per then use the Set Step Per Unit  button on the settings page and Mach will calc for you. This however will only ever be as accurate as your measuring and its normally much more accurate calculating them yourself.

Ok, I enabled one home switch because the limit switches are wired in series so I only have one but I'm not sure how this works. I want to reference using a home switch but not sure what I'm doing. I now have X Home enabled port 1/ pin 13, same as X++ limit switch. Now what? Also I have acme drive screws, 10 TPI, 5 start. How can I calculate them myself?

If you have limits on all axis and they are all wired in series you can use that single input as Limits and Home switches for ALL axis, just set them all to the same port and pin number. You will then possibly have to choose the home negative in Homing and limits for some of the axis, just depends on your setup.

Thats how I had it set up originally because I have limits on all four screws, each end, 8 total. Scott (from Mach) said since I had only one pin and wired in series, it would not be a benefit.

I don't understand the Homing Neg option. As of now, they are all checked red. So now I have all set up as limits and home switches but not sure about the Home Neg.

I used the formula 200*10*4 and came up with 8000 and the steps are still way off.
