Hi!

I have been working out for controlling all led lights in my tool changer 3d printer.

I use 50 pieces of dotstar leds and first 18 are bottom of bed, next 29 are in frame and last 3 in toolchanging head. Bed leds are for notification light use to see the status of the printer.

Heres some code for Led control loop. If there is m1 or something in print that requires waiting the operator, variable named global.LEDMode is set to Wait and leds are set to white and bed blue flashing loop will start. If global.LEDMode is set to Printing, leds are set to green and white static.

; LED control loop
while 1=1

  ; Wait (White, Bed flashing blue) For M1 and filament change etc
  while global.LEDMode = Wait    ;1 <---this while could be if, i guess?
    M150 B255 S18 P255 F1		; LED Bed = Blue
    M150 R255 U255 B255 S29 P255 F1	; LED Frame = White
    M150 R255 U255 B255 S3 P255		; LED ToolHead = White
      while global.LEDMode = Wait	; Entering flashing loop
        G4 P1000			; 1000ms time delay
        M150 B255 S18 P0		; Blue off
        G4 P1000			; 1000ms time delay
        M150 B255 S18 P255		; Blue on
        if global.LEDMode != Wait
          break			        ; Exit flashing loop
  break   ;1 <---then this would be removed

  ; Printing (White, Bed static green)
  while global.LEDMode = Printing       ;<--- here while is necessary?
    M150 U255 S18 P255 F1		; LED Bed = Green
    M150 R255 U255 B255 S29 P255 F1	; LED Frame = White
    M150 R255 U255 B255 S3 P255		; LED ToolHead = White
    if global.LEDMode != Printing
      break			        ; Exit loop

will this work like i expect?

Meta command doesnt work yet because i have 3.2.2 firmware.

Will that flashing loop work? does it(g4) stop printer if i want same loop for toolchange script?

Thank you in advance!

@dc42 Hi, yesterday I couldn't answer because this site said i was spamming...

tried that daemon file but it didnt work

it was something like that

set global.LEDMode = {global.LEDModeLast}

; WorkLight (Bed static white, Frame static white, ToolHead static white)
while global.LEDMode = "WorkLight"		; Enter loop
  M150 R255 U255 B255 S18 P255 F1		; LED Bed = White
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 B255 S3 P255			; LED ToolHead = White
  if global.LEDMode != "WorkLight"
    set global.LEDModeLast = "Worklight"
    break								; Exit loop
 
 
 
  ; Homing (Bed flashing yellow, Frame static white, ToolHead flashing yellow)
while global.LEDMode = "Homing"			; Enter loop
  M150 R255 U255 S18 P255 F1			; LED Bed = Yellow
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 S3 P255				; LED ToolHead = Yellow
  G4 P1000							; 1000ms time delay
  M150 R255 U255 S18 P0 F1			; LED Bed = OFF
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 S3 P0				; LED ToolHead = OFF
  G4 P1000							; 1000ms time delay
  if global.LEDMode != "Homing"
    set global.LEDModeLast = "Homing"
    break								; Exit loop
 
 
 
; Printing (Bed static green, Frame static white, ToolHead static white)
while global.LEDMode = "Printing"		; Enter loop
  M150 U255 S18 P255 F1				; LED Bed = Green
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 B255 S3 P255			; LED ToolHead = White
  if global.LEDMode != "Printing"
    set global.LEDModeLast = "Printing"
    break		

i also tried to change while to if

set global.LEDMode = {global.LEDModeLast}

; WorkLight (Bed static white, Frame static white, ToolHead static white)
if global.LEDMode = "WorkLight"		; Enter loop
  M150 R255 U255 B255 S18 P255 F1		; LED Bed = White
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 B255 S3 P255			; LED ToolHead = White
  set global.LEDModeLast = "Worklight"
 
 
 
  ; Homing (Bed flashing yellow, Frame static white, ToolHead flashing yellow)
if global.LEDMode = "Homing"			; Enter loop
  M150 R255 U255 S18 P255 F1			; LED Bed = Yellow
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 S3 P255				; LED ToolHead = Yellow
  G4 P1000							; 1000ms time delay
  M150 R255 U255 S18 P0 F1			; LED Bed = OFF
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 S3 P0				; LED ToolHead = OFF
  G4 P1000							; 1000ms time delay
  set global.LEDModeLast = "Homing"
 
 
 
; Printing (Bed static green, Frame static white, ToolHead static white)
if global.LEDMode = "Printing"		; Enter loop
  M150 U255 S18 P255 F1				; LED Bed = Green
  M150 R255 U255 B255 S29 P255 F1		; LED Frame = White
  M150 R255 U255 B255 S3 P255			; LED ToolHead = White
  set global.LEDModeLast = "Printing"

i also tested that the daemon.g is executed by adding m291 there and it works. but the led control dont work

@phaedrux BOSSA says "File operation exceeds flash size". I have tried Fallback procedure #1 and #2, same results, DIAG Led stays dimmed. Whats next?

Hi! I'm building new printer with Duet3 and Raspberry PI 4. I got this error message "Board is not available (no header)". DIAG Led on Duet is dimmed. On computer Duet shows as unknown device and com3 port. I installed Bossa and now it is Bossa Program Port. Then i tried updating firmware with Bossa but it says "File operation exceeds flash size". What can i do now?

@chrishamm thats nice! i forgot to mention that i got a raspberry with duet...

@dc42 interesting

@dc42 echo {"Kuumapään lämmittäminen " ^ global.Temperature ^ "-asteeseen"}

this works also like it should. there is a some problem with that m291 comment

@dc42 echo works but that other one doesn't. I don't understand what it could be due to

@dc42 how can i do that? Its not working in console or any macros if i make them in dwc.

@dc42 and i noticed that this does not work because of "ä" letter.

It says Error: M291: control character in string

M291 R"Filamentin lataus" P{"Kuumapään lämmittäminen " ^global.Temperature^ "-asteeseen"} S1 T3

Like this it works:

M291 R"Filamentin lataus" P{"Kuumapaan lammittaminen " ^global.Temperature^ "-asteeseen"} S1 T3

Also this doesnt work. If i change "ä" to "a" it will work like it should.

M291 R"Filamentin lataus" P"Kuumapään lämmittäminen asteeseen"S1 T3

@dc42 okay.

i fixed it with this

when those array-valued variables will come?

Hi. is this a bug or am i just not able to do it right?

this is my homeall macro.

set global.LEDModeLast = {global.LEDModeMemory}
set global.LEDMode = {global.LEDModeLast}	; LEDMode = Last

problem is this, it says=
Error: {global.T{state.currentTool}ParkX}unknown variable 'T' of homeall.g

i tried to write to the console

echo {global.T{state.currentTool}ParkX}

it will show just what i want to see. but in this homeall macro, it wont work.

what is this about?

Thanks in advance!
