lua exaples

hi,

are there examples awailable how to write lua modules for repetier server? maybe on github?

Repetier

No, but here a sample that makes a led blink and shuts down pi on button press

rs = RepetierServer()

local GPIO = periphery.GPIO

local loopCounter = 0

local blink = false

local blinkOn = true

local lastButton = true

local gpioBlink = nil

local gpioButton = nil

function setup()

  print("lua setup called")

  gpioBlink = GPIO(3, "out")

  gpioButton = GPIO(2, "in")

  print("lua setup finsihed")

end

function loop()

  print("loop")

  loopCounter = loopCounter + 1

  if lastButton ~= gpioButton:read() then

    lastButton = not lastButton

    print("Button " .. tostring(lastButton))

    if lastButton then

      blinkOn = not blinkOn

      os.execute("sudo /sbin/shutdown -h now")

    end

  end

  if loopCounter >= 100 then

    loopCounter = 0

    if blinkOn then

      blink = not blink

      gpioBlink:write(blink)

      print("Blink:" .. tostring(blink))

    end

  end

end

Also a snippet to send a gcode(M119)  to all printers being active:

function sendM119()

  pList = rs.printerList

  for _,printer in pairs(pList) do

    if printer.activated then

      printer:injectManualCommand("M119")

    end

  end

end

Watch out with shutdown example - a small error there will shutdown pi as soon as server starts!
Just copy the lua script to  /var/lib/Repetier-Server/lua and restart server. Watch server.log as script errors and print commands get written there. So that is your main point in finding errors in scripts.
