You will need to make sure the path to the module  is included before the require, this is already set in the screen load script but still ok to put again

Code: [Select]

    local profile = mc.mcProfileGetName(inst)
    local path = mc.mcCntlGetMachDir(inst)
   
    package.path = path .. "\\Profiles\\" .. profile .. "\\Modules\\?.lua;" .. path .. "\\Modules\\?.lua;"
when using require it will look in these path locations for the module

Nice example ;-)

Simple way to put it is Private and Public Functions

No prefix = Private function being used internally by the module and cannot be run from outside of the script
With prefix = Public function that can be run/called externally using the prefix you gave it during requiring.

Prb is a derived class (or module for lua) of Probing.

when requiring a module the module name is replaced by what we tell it, in this case its prb, so although you will see Prb.SingleSurfZ its actually running Probing.SingleSurfZ.

seems weird but look at it this way, lets take a module that creates a button called btnCreate and within that module there is a function btnCreate.createButton(coords etc)

we need 3 buttons so we can do this

local btn1 = require btnCreate
local btn2 = require btnCreate
local btn3 = require btnCreate



btn1.createButton(coords etc)
btn2.createButton(coords etc)
btn3.createButton(coords etc)

so btn1 -2 and 3 becomes derived classes/modules of btnCreate.

This runs a function that is within the Screen Load Script that simply runs an mdi code.

Code: [Select]

function GoToWorkZero()
    mc.mcCntlMdiExecute(inst, "G00 X0 Y0 A0")--Without Z moves
    --mc.mcCntlMdiExecute(inst, "G00 G53 Z0\nG00 X0 Y0 A0\nG00 Z0")--With Z moves
end

Go into your Mach4 Config and select the Tools tab, You will find a "Tool Change Type" section, change this too "T on M6 line is tool to use", Voila it should now work ;-)

Ok have a little play with something like this

in the events tab for the enable button delete the Down Action and place this in the Down Script

Code: [Select]

local inst = mc.mcGetInstance()

function CheckHomeState()
    local en_axis = 0
    repeat
        local Is_Enabled = mc.mcAxisIsEnabled(inst, en_axis)
            if Is_Enabled == 1 then
                local is_Homed = mc.mcAxisIsHomed(inst, en_axis)
                if is_Homed ~= 1 then
                   HomeDialog()
                return  
                end
            end
        en_axis = en_axis + 1
    until( en_axis == 6 )
mc.mcCntlEnable(inst, 1)
end

function HomeDialog()
local h_dialog = wx.wxMessageDialog(wx.NULL,"Clicking Ok will Home all Axis, Cancel will abort", "Warning Machine Not Homed",wx.wxOK + wx.wxCANCEL)
local test = h_dialog:ShowModal()
    if test == wx.wxID_OK then
        mc.mcCntlEnable(inst, 1)
        wait = coroutine.create (RefAllHome)
    else
        scr.SetProperty('tbutton2','Button State','Up')
        return
    end
end

CheckHomeState()
Seems to work ok on my machine :-)
