Lua GcodeExecute
« on: October 07, 2015, 11:04:26 AM »
I am wanting to execute g code using a variable.  In Mach3 you were able to do this easily but I can't figure out how to do it in Lua.
Here is the macro below.  The macro retrieves the reg val just fine but the part I'm concerned with are lines 8 and 9.  I have set the variable to my reg val.  Now how do I use the variable in the g code line. 


N01  function m1020() --Test
N02  --Macro to move programable coolant nozzle.
N03  --using registers for nozzle positions.
N04  inst = mc.mcGetInstance()
N05  hreg = mc.mcRegGetHandle(inst,"gRegs0/Test1")-- Position 1 2.5
N06  val = mc.mcRegGetValueString(hreg)
N07  val = tonumber(val)
N08  local ProgCoolant = val
N09  mc.mcCntlGcodeExecuteWait(inst, "G90G00C", ProgCoolant)
N10  end
N11  if (mc.mcInEditor()== 1) then
N12      m1020()
N13  end

See if this example helps.

Code: [Select]
local inst = mc.mcGetInstance() -- Get the instance of Mach4
local xval = mc.mcProfileGetString(inst, "RememberPos", "X", "NotFound") -- Get the register Value
local yval = mc.mcProfileGetString(inst, "RememberPos", "Y", "NotFound") -- Get the register Value
local zval = mc.mcProfileGetString(inst, "RememberPos", "Z", "NotFound") -- Get the register Value

if(xval == "NotFound")then -- check to see if the register is found
wx.wxMessageBox('Register xval does not exist.\nYou must remember a postion before you can return to it.'); -- If the register does not exist tell us in a message box
elseif (yval == "NotFound")then -- check to see if the register is found
wx.wxMessageBox('Register yval does not exist.\nYou must remember a postion before you can return to it.'); -- If the register does not exist tell us in a message box
elseif (zval == "NotFound")then -- check to see if the register is found
wx.wxMessageBox('Register zval does not exist.\nYou must remember a postion before you can return to it.'); -- If the register does not exist tell us in a message box
else
mc.mcCntlMdiExecute(inst, "G00 G53 Z0.0000 \n G00 G53 X" .. xval .. "\n G00 G53 Y" .. yval .. "\n G00 G53 Z" .. zval)
end

Thanks Chaoticone!! That did the trick.  Just needed ".." instead of ","
Works Great!! =)
