Hi, has someone got a snippet of code that would allow me to set the Jog Rate % via the Lua linked to a button.

I can create button and link it to the button etc....

thanks in advance....

It is in 2 parts.
I put it all in the Mach Screen Load Script.
It does use some custom registers.

Part 1.
[mc.ISIG_INPUT11] = function (state)
      local AltRegH = mc.mcRegGetHandle(inst, 'iRegs0/Alt')
   local AltVal = mc.mcRegGetValue(AltRegH)
   if (state == 1) then
      if(machEnabled==1) then
         if (AltVal == 0) then
         CutSpeedMinus()
         elseif (AltVal == 1) then
         CutSpeedPlus()
         end   
      end
   end
end,

Part 2
--------------------------------------
--cut speed plus function
---------------------------------------
function CutSpeedPlus()
   local CutMax = 200
   local CutNow = mc.mcCntlGetFRO(inst)
   if (CutNow >= CutMax) then
      CutNow = CutMax
   else
      CutNow = CutNow + 10
   end
   mc.mcCntlSetFRO(inst, CutNow)
end

--------------------------------------
--cut speed minus function
---------------------------------------
function CutSpeedMinus()
   local CutMin = 10
   local CutNow = mc.mcCntlGetFRO(inst)
   if (CutNow <= CutMin) then
      CutNow = CutMin
   else
      CutNow = CutNow - 10
   end
   mc.mcCntlSetFRO(inst, CutNow)
end

Sorry previous post was for cut speed
Here is what i have for jogging speed

Part 1
[mc.ISIG_INPUT19] = function (state)
      local AltRegH = mc.mcRegGetHandle(inst, 'iRegs0/Alt')
   local AltVal = mc.mcRegGetValue(AltRegH)
   if (state == 1) then
      if(machEnabled==1) then
         if (AltVal == 0) then
         JogSpeedMinus()
         elseif (AltVal == 1) then
         JogSpeedPlus()
         end   
      end
   end
end,

Part 2
--------------------------------------
--jog speed plus function
---------------------------------------
function JogSpeedPlus()
   local JogMaxS = 100
   local JogMax = tonumber(JogMaxS)
   local JogNowS = scr.GetProperty('sliJogRate', 'Value')
   local JogNow = tonumber(JogNowS)
   if (JogNow >= JogMax) then
      JogNow = JogMax
   else
      if (JogNow >= 5) then
         JogNow = JogNow + 5
      else
         JogNow = 5
      end
   end
   rc = scr.SetProperty('sliJogRate', 'Value', tostring(JogNow))
end

--------------------------------------
--jog speed minus function
---------------------------------------
function JogSpeedMinus()
   local JogMinS = 1
   local JogMin = tonumber(JogMinS)
   local JogNowS = scr.GetProperty('sliJogRate', 'Value')
   local JogNow = tonumber(JogNowS)
   if (JogNow <= JogMin) then
      JogNow = JogMin
   else
      if (JogNow >= 6) then
         JogNow = JogNow - 5
      else
         JogNow = JogNow - 1
      end
   end
   rc = scr.SetProperty('sliJogRate', 'Value', tostring(JogNow))
end

Thanks for the reply - a question if I may?

if (AltVal == 0) then
                JogSpeedMinus()
          elseif (AltVal == 1) then
                JogSpeedPlus()
          end
What does "AltVal" represent e.g. why are you checking if it's equal to 1 or 0?

Are you checking if the AltKey is pressed or not?

thanks again

On my handheld pendant every button can have 2 things it does.
When you hold down what I call the "Alt" button it does the second operation for the button.
AltVal is just a variable that lets me know what the register is set at so i know which function to do when the button is pressed.

Hi, mine was easier - I just wanted a few buttons on the screen with preset values attached to them.

All I needed was

Calling for 10%  -  "JogSpeedSet(10)" on the button script.

function JogSpeedSet(JogSpeed)
if(machEnabled==1) then
            rc = scr.SetProperty('sliderJogRate', 'Value', tostring(JogSpeed))
end
end
I use a ShuttlePro and I am still trying to mimic the functions on that. I used to have a couple of macros I used to call to set Jog Speed on that.

You can't do that on the "Upgraded" Mach4...but you could on Mach3  you can only seem to run Gcode.

Thanks again

Rimmel,

What exactly are you trying to do that can not be done in Mach4?
It is different but I found how to do everything plus a lot more.

I thought you were wanting a mechanical button.
If you just want a button in the software to change to a specific speed then yours is much easier.
I have mine set up so every push changes the speed by 5%.

Rimmel,

Run the function I last quoted from a button on the Shuttlepro

It seems you cannot. You can only run pre-assigned functions or a line of gcode.

I know nothing about the Shuttle Pro other than it exists.
Is there a Plugin for it?
Can you use the buttons as an input into Mach4?
If you can then you can do something like part 1 of my earlier examples.
