Set up Z Home Distance
« on: November 15, 2007, 07:24:10 PM »
I finally got all three axis home, and limits working. I have read in the manual but can not find how to set the
distance that each axis comes off the home switch. My main problem is the Z axis, I would like to have it come off
the home switch 1".
Thanks for any assistance!

Thanks for the quick reply! Unless I misss something that only resets the readout
to the desired reading. I have my Z axis offset set to 1.00 and the readout is 1.00
but the travel off the home switch is still the same, maybe .125.
Thanks!

There is no direct setting in Mach to make it come further off the home switch.

You can increase the debounce but that is a rather crude way to do it.

You would be best to add some VB code to the Fef All button.

For example put this in the Ref All button to move the Z down one inch after homing.

DoButton( 24 )
While IsMoving()
Wend
Code "G0 Z-1"
While IsMoving()
Wend
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )


Or individual axis home buttons if you have them.

I use the G28 home locations on the homing/limits page as poppabear mentioned then put the following code to go home button
Code"G28"
While IsMoving
Wend
DoButton(7)

you could also add it to the ref all home button as Greg suggested and do it all with one click  ;)

Just double click on the Screen4.exe, you will find it in your Mach3 folder. Once opened just click file and Open then browse to the screenset you wish to open (standard is 1024.set) and you can then alter as you wish.

Thanks Hood!! I know some of my questions seem like I never read manuals or posts, but there
is sooooo much to grasp it takes a little nudge from kind people like yourself and all the others
who have nudged me along the way.

After looking in the Mach3 folder I do not have Screen4.exe anywhere in my Mach3 Folder. Is there
some where I can down load it? I'm running a full registered version.
Thanks again!!

Just note you do not need Screen4 to add a script to the Ref All button.

Access button scripts by going Operator / Edit Button Script then press the relevant button which will be winking.

This will open the button script in the VB Script Editor.

If however you wish to make a new button on screen or other additions or alterations then  Screen4 is the way to go.
