Title: How to send command to the motion controller while probing?
Post by: dibor on December 26, 2024, 04:21:39 PM

Hello to ALL.
I'd like to engage some pin of motion controller only while probing process.
How can I do this?
Script, LUA ??

Thank U

Scripting.  Place probeon.lua and probeoff.lua files in the Mach profile's macro directory.  They are just like M code scripts.  Meaning the file name and the function name inside them need to match.  Case matters.  Make the names all lower case for zero confusion. 

in probeon.lua:

Code: [Select]

function probeon(probenumber)
    -- script any signal or I/O functions here.
end function

in probeoff.lua:

Code: [Select]

function probeoff(probenumber)
    -- script any signal or I/O functions here.
end function

Thank a lot Steve.

Will try this way :)

These functions will be usable for the "Touch" process?

Best Wishes.

Doesn't work :(

Code: [Select]


function probeon(G31)
     local inst = mc.mcGetInstance()
     mc.mcCntlSetPokeysOutput(inst, 45, 1)
end


Do not understand :(

This code also doesn't work :(

Code: [Select]

function probeon(G31)
local inst = mc.mcGetInstance()
local hSig, rc = mc.mcSignalGetHandle(inst, mc.OSIG_OUTPUT45)
mc.mcSignalSetState(hSig, 1)
end

Anybody can kick me to the right direction?    ;D

Hello to ALL.
I see nobody has anything to say :(
So, after head crash and putting out some part of the hair and taking chat GPT for assistant I got working script.
Have save it as M101.mcs
I have use SMART.MER/2 – signal merger with probe guard function by topcom, he is able to generate ESTOP signal, when connected probe is triggered in the
unexpected moment. It can protect a probe from damage.
This board has inputs that blocks guard function, so I need to provide high level from motion controller while probing process.
Here my script, maybe will useful for somebody else :)

Code: [Select]

local inst = mc.mcGetInstance()  -- Get the Mach4 instance
local outputSig = mc.OSIG_OUTPUT45  -- Define OUTPUT45 signal
local prevState = -1  -- Variable to store the previous state

-- Function to check probing state and control OUTPUT45
function CheckProbingState()
    local state = mc.mcCntlGetState(inst)  -- Get the current system state

    -- Check if the state has changed
    if state ~= prevState then
        mc.mcCntlSetLastError(inst, "Current State Changed: " .. tostring(state))  -- Log state change

        -- Get the handle for OUTPUT45 signal
        local hSig = mc.mcSignalGetHandle(inst, outputSig)

        if state == 202 then 
            mc.mcSignalSetState(hSig, 1) 
            mc.mcCntlSetLastError(inst, "PoKeys57CNC: Probing Active, OUTPUT45 ON!")
        else
            mc.mcSignalSetState(hSig, 0) 
            mc.mcCntlSetLastError(inst, "PoKeys57CNC: Probing Completed, OUTPUT45 OFF!")
        end

        -- Update the previous state
        prevState = state
    end
end

-- Timer checks state but only updates OUTPUT45 on change
wxTimer = wx.wxTimer()
wxTimer:Start(100, wx.wxTIMER_CONTINUOUS)
wxTimer:Connect(wx.wxEVT_TIMER, function(event)
    CheckProbingState()
end)


•   OUTPUT45 turns on only when probing starts (state == 202).
•   OUTPUT45 turns off when probing stops.
•   The signal only changes when the state actually changes.

Best Wishes.

Hi to ALL.

Possible to run as PLC script:

Code: [Select]

if not inst then inst = mc.mcGetInstance() end
if not outputSig then outputSig = mc.OSIG_OUTPUT45 end
if not prevState then prevState = -1 end

function CheckProbingState()
    local state = mc.mcCntlGetState(inst)
    if state ~= prevState then
        mc.mcCntlSetLastError(inst, "State: " .. tostring(state))
        local hSig = mc.mcSignalGetHandle(inst, outputSig)
        if hSig ~= 0 then
            if state == 202 then
                mc.mcSignalSetState(hSig, 1)
                mc.mcCntlSetLastError(inst, "PoKeys57CNC: Probing Active, OUTPUT45 ON!")
            elseif prevState == 202 then
                mc.mcSignalSetState(hSig, 0)
                mc.mcCntlSetLastError(inst, "PoKeys57CNC: Probing Completed, OUTPUT45 OFF!")
            end
        end
        prevState = state
    end
end

CheckProbingState()

All the best to ALL

Script is WORK!
