Filament runout

mwk

Can I add a filament runout to the server on the raspberry Pi?

Repetier

With some programming skills. Such a solution is also already available here:

https://github.com/Raabi91/filament_runout_Repetier

but you can also use a lua module to query a pin and start a pause. Here an example that sends M416 when power detect pin is off for 500ms. Shoudl be easy to convert to send "@pause No Filament" when a pin signals no filament:

rs = RepetierServer()
local GPIO = periphery.GPIO

local powerPin = 2
local gpioPower = nil
local powerOk = false -- default signal for power
local powerFailCount = 0

function setup()
   gpioPower = GPIO(powerPin, "in")
   -- powerOk = gpioPower:read()
end

local loopCounter = 0

function sendPowerLost()
  print("Power lost detected - signaling to printer")
  pList = rs.printerList
  for _,printer in pairs(pList) do
    -- print("Printer " .. printer.slug .. " active " .. (printer.activated and 'true' or 'false'))
    if printer.activated then
      printer:injectManualCommand("M416")
    end
  end
end

function loop()
  if powerOk ~= gpioPower:read() then
    powerFailCount = powerFailCount + 1
    if powerFailCount == 500 then
     sendPowerLost()
    end
  else
    powerFailCount = 0
  end
end

Thanks. Will have a look
