LED controlling with meta commands

K01571N3N

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!
