Hi,
if I'm not mistaken it is not permissable to have multiple GcodeExecuteWait() statements one after the other.

You'll have to rewrite them as a single call with line characters beteewn lines.

Hi,

I purchased this partly because it appears to have been endorsed by the Mach3 / Artsoft people

I don't recall seeing anything about this board and certainly not from Artsoft/NFS. Where did you get that info from?

Hi,
I just loaded the file and got a toolpath like yours a series of diagonal cuts. That's what the Gcode is telling the machine to do and the machine is doing it.

What were you expecting the code to do?

Mach4 General Discussion / Re: Mach 4 Goto Zero
« on: February 07, 2018, 12:45:11 AM »
Hi,
OK, that function GoToWorkZero() is correct, the two lines which follow it and are commented out are just so you can see what is included in the function,
they were never intended to be uncommented.

The actual function is in the screenload script and has those two lines included, you comment out the one you don't want and leave the other.
What you have in fact done is  to have two definitions of that function.

This is whats it my screenload script at the moment:
Code: [Select]
---------------------------------------------------------------
-- Go To Work Zero() function.
---------------------------------------------------------------
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

I have a couple of other custom scripts so I guess you would find this code around line 220 in the screenload script. This is the code you should edit/replace or whatever.
You'll have to go back and apply  comment marks to those lines you uncommented earlier.

A couple of points that may help or certainly save you some grief in times to come.
Its great that you are starting to modify screensets and things, it very Much part of Mach4 that you customize it to suit your machine. Like you I use wx4.set.
There is a problem with that though....if I go and make  new buttons and controls, screen scripts and so on they get saved to wx4.set. That means I'm screwing
up my 'clean' copy but even that's not a big problem. What happens when I download the latest and greatest Mach4 build from NFS? The screenset wx4.set will
get overwritten with the latest and greatest wx4.set too. That means all my tweaks and scripts have been wiped....bugger!

The trick is to make a copy of wx4.set but call it something personal like Craigswx4.set and use that screenset in your profile and all your tweaks get saved to it and
won't be overwritten when you update Mach.

Next point is that there are quite a number of chunks of Lua code, the sreenload script you've encountered but there are others like the PLC script, the PMC script
and so on. When Mach runs ALL these scripts get rounded up and compiled into one big file called the Lua script. If you go to the operator menu there is an option
to view it. Interesting and you can use search functions to find specific bits of code but you CAN'T edit it, its just for looks!

Another point worth mentioning is that when you start writing your own scripts you will be putting some bits in the screenload script and other bits elsewhere.
If you make a mistake it can be awfully hard to track down where it is. What I do and recommend to you is that you make a folder in your profile and write all
your code in it. You'll be able to use the editor and debugger, and if you really screw it up you only have one bad file to dig out to get Mach running again.
Once your happy that the code will work without crashing Mach that's when you place it in the screenload script or wherever.

Hi,
and just so there no misunderstanding what screenset are you using?

Hi,
on the screenshot I posted the script attached is actually a function:

GoToWorkZero()

does your installation say the same?

The reason I ask is because that code fragment you posted doesn't look standard.

« on: February 06, 2018, 03:57:32 AM »
Hi Dany,
have tightened up on the code. Have included a loop that retries the GcodeExecuteWait() call to a maximum of five times. My testing has shown that its now
reasonably robust. Its time for you to put it into action and see how it performs in the real world.

Code: [Select]
function OfflineButton()
local inst=mc.mcGetInstance()
local hsigenable=mc.mcSignalGetHandle(inst,mc.OSIG_ENABLE0)
local hsigbuttonstate=mc.mcSignalGetHandle(inst,mc.OSIG_OUTPUT2)
if (mc.mcCntlGetState(inst) ~=0)then mc.mcCntlCycleStop(inst)end
if (mc.mcSignalGetState(hsigenable)==1) then
    if (mc.mcSignalGetState(hsigbuttonstate)==1) then
        -- Mach is enabled and the servos are 'online'
        -- Need to save current position and set servos 'offline'
        local Xpos=mc.mcAxisGetMachinePos(inst,mc.X_AXIS)
        local Zpos=mc.mcAxisGetMachinePos(inst,mc.Z_AXIS)
        mc.mcCntlSetPoundVar(inst,500,Xpos)
        mc.mcCntlSetPoundVar(inst,501,Zpos)
        mc.mcSignalSetState(hsigbuttonstate,0)
    else
        --Mach enabled but servos 'offline'
        --Need to restore current position and reset servos 'online'
        local Xpos=mc.mcCntlGetPoundVar(inst,500)
        local Zpos=mc.mcCntlGetPoundVar(inst,501)
        local rc=1
        local iter=0
        repeat
            rc=mc.mcCntlGcodeExecuteWait(inst,'g53 g0 x'..Xpos..' z'..Zpos)
            iter=iter+1
            if iter >=5 then wx.wxMessageBox('GcodeExecuteWait() Failed') break end
            if rc~=0 then mc.mcCntlEnable(inst,0) mc.mcCntlEnable(inst,1) end
        until (rc==0 ) 
        if (rc==0) then mc.mcSignalSetState(hsigbuttonstate,1) end
    end
else
    --Mach disabled....do nothing
end
end
if ( mc.mcInEditor()==1) then
    OfflineButton()
end

Hi,
what screenset are you using?

I'll take a guess and say wx4.set. Is the <Go To WorkZero> button the same as pictured below?

If so go to the edit screen and is the 'left up script' the same also?

The code for that function is in the screenload script. It is conveniently placed and annotated so that users may have its behavior suit their wishes.

Mach4 General Discussion / Re: How can I edit lua script?
« on: February 06, 2018, 01:05:07 AM »
Hi,
the code IS in the screen load script. It is  the last entry in the signal library. I noted that your screenshot showed the Lua script, which is useful for see the
complete picture, but you need to edit the screen load script.

It is not in fact anything to do with the toolchange. All it does is define a certain action to take if a certain signal changes state, the signal is OSIG_TOOL_CHANGE

The toolchange macro will almost certainly be in your macros folder and it will be called from your Gcode job or MDI. If as part of that macro the signal is set
then the signalscript will catch it and take the action defined for that signal in the signal library.

Craig
