Hi,

I have a VB script that I copied form http://cockrum.net/cnc.html .

Im using the touchplate code to auto-zero my axes.

Currently in Mach3 I have to go to Operator->VB Script Editor then run the VB script from there, but it would be less hassle if i could assign the code to the standard "zero x", "zero y" and "zero z" buttons on the existing Mach3 screen.

It would also be nice to make a button that homes all three axes.

I can't seem to find how to do this in the Mach3 settings.

Any help is greatly appreciated

rename it for example m2000
save it in your current macro file. (my computer, mach3,macros, my mill etc?)

just type into mdi m2000

if you want to add a button to a screen download machscreen. very easy to use after about 10 mins youl be able to do anything with the mach screens!

or you can use operator, edit button code
if the button you want flashes you can edit it, otherwise download mach screen and add a button to the page you want

Thanks for that.

I did have a look at machscreen yesterday, but thought I'd have to make an entire new interface from scratch.

Can I use machscreen to add a single button to the screen I already have?

[battwell]

yes. just open the page you want in machscreen
in the smaller box you will see add and a drop down list
select button
cursor on screen where you want it and click
then edit the button in the properties box

save the screen set as a different name if you want when your done.
in mach select view, loadscreens and select the new name
save settings under view tab
(ive had to add 100 leds, 18 buttons to one of my screens)

Very Nice.

Im at work now, but will try to do something tonight

Thanks Again

Thanks,

That went smoother than I expected!
Can I please ask what Gcode I would use to set the x,y or z coorinate to a defined number?

This is my current Z-axis zeroing code:

Message( "Auto Zeroing..." )
If IsSuchSignal (22) Then
code "G31 Z-3 F20"
While IsMoving()
Wend
Call SetDRO( 2, .060 )
code "G1 Z1"
End If



Trouble is, if by some freak instance the z-coordinate is less than -3, it will actually move upwards rather than downwards when I press the auto-zero button.

If I could set Z to something like 10 inches before the G31 command in the code, this problem would be resolved.

You're already using it - SetDRO(2,.060) sets the Z DRO to .060.

However, SetDRO is from older versions of mach3. You should be using SetOEMDRO instead, SetOEMDRO(802,10) should set the Z DRO to 10.

A list of the OEM DRO numbers is here.
