Your welcome. Let us know if you have any more trouble. Here is a little more info that might help. It is an old one that I copied and pasted.
 Here is how you do the math. I will give you mine as an example. What we need to know is, How many pulses from Mach will it take to move the machine 1 of your units? (inch,mm) Mine is in inches. 1 inch = 10,000 pulses on mine. This is how I came up with the number.
My steppers have 200 pulses per revolution. ( 360 degrees divided by 1.8 degrees = 200 )
Micro stepping = 10. So 200 X 10=2,000
Motor to screw gearing is 1-1. So 2,000 X 1=2,000
Screw lead is .200 of an inch. My screw will have to turn 5 rounds to move the nut 1". 1.0 divided by 0.200=5. So 2,000 X 5=10,000.
Do the math first. Then we can move on. Once we are certain of all of this, dialing it in should be easy.

Sound to me like you may be picking up a little bit of noise. In general config, set your debounce to 100 and see if that helps. Does it do it while on the program run page?

Hey, I didn't know what one was when I was born either. Somebody had to tell me. I was referring to a dial indicator. Here is a link.
http://catalogs.shoplocal.com/jlindustrial/index.aspx?storeid=1038424&circularid=7228&jlpass=1278&loggedin=false&itemcount=0&jsessionid=ymq5bx1yd2tqplaubiwsfevmcqfcyiv0&pagenumber=1300

These are cheap. Not the best, but cheap.

What kind of threaded rod did you get? 1/2-20, 3/8-16,etc.? The last two digits in the previous numbers indicate the thread pitch. 1/2-20 says it is 1/2" in diam. and 20 TPI (threads per inch). 1"divided by 20 = .050" travel per round.

Hey Mark,
     Have you verified that you steps per are right in motor tuning?
Hey,
    Checking your backlash should be no problem if you have an indicator. Put the indicator on something solid. Jog your axis until you move the indicator to a reading of about half of its travel. Write down the reading on the indicator. Jog the axis in the other direction by a set amount, say .010" and see how much difference the indicator shows. If the indicator says you moved .005 and Mach says it has moved .010 then you have .005" backlash. With that being said, you really need to know the pitch of your ballscrew first. I would say your steps per will be 10,000. You can check this with your indicator also. Set up as before., only this time run the axis in until it just starts to move the needle on the indicator. Write down your reading. Going in the same direction give the axis a move with Mach. If Mach thinks it moved it .010" and your indicator says it moved .010", your steps per are right. ;D

Justin,
    Do you have your softlimits enabled? There should be a button on your screen that says soft limits. Jog all axis to the point where they would be out of the softlimits range and enable them.

I'm not sure what you are trying to do, or the problem is with the Ref. home etc. If you want to zero your dro, click the zero x,y,z beside the dro. This sets up your work coord. The ref all home button is where your limits are made. When you click it all of your axis should go to machine zeros. All of the buttons I have mentioned are in this screen shoot.

Jerald,
    You are off to a good start in my book. This is the kind of post I like to see. Yes, thanks Brian, Art, Benny, Jason, Hood, Graham etc. The list goes on and on.

Good Kevin,
    I would suggest downloading the latest version of Mach also.

I look for Tony to jump in this thread at some point.

Give the three finger salute. Ctrl, Alt, Delete. Task manager, processes. End the process. You may want to look at the optimization file in the downloads section of this forum. What version of Mach are you running?
