      I get this error

      Error: Bad command: global.ledState = 0
      Warning: both space and tab characters used to indent blocks at/before line 41
      Error: in file macro line 46 column 28: meta command: unknown variable 'ledState'

      line 46 --> if global.ledState = 0

        Remove the '.' between "global" and "ledState" at line 23.

        Error: in file macro line 46 column 28: meta command: unknown variable 'ledState'

        line 46 --> if global.ledState = 0

        That's a result of the previous error.

        As it says.

          Well I did say it was untested 🙄

          Error: Bad command: global.ledState = 0

          change this

          if !exists(global.ledState)
	global.ledState = 0

          to this

          if !exists(global.ledState)
	global ledState = 0

          Warning: both space and tab characters used to indent blocks at/before line 41

          I don't see any spaces mixed with tabs on my code.
          If you copied and pasted or modified the code you may have introduced some.

          If you use an editor like notepad++ or RJ TextEd, you can set it to display spaces and tabs.

              I´m testing it but all neopixel are shining red . After a while all neopixel turned off.
              Can we create a Macro for testing?

                As I said, I don't have a neopixel.
                It's possible I have made an error with the M150 calls.
                I have modified the code to add some echo commands and fix an error.
                Tt seems to do the loops correctly.
                Please try this and if the echos are correct but the LED control is wrong then you need to focus on the M150 commands to get the on/off correct

                ; 0:/sys/daemon.g


if !exists(global.runLED)
	global runLED = true
	
if global.runLED = false ; send "set global.runLED = false" to stop daemon if needed
	M99 ; exit daemon.  

if !exists(global.ledSize)
	global ledSize = 58 ; modify to number of LED's in neopixel.
if !exists(global.ledDelay)
	global ledDelay = 2 ; modify to change delay. 
if !exists(global.rLED)
	global rLED = 255 ; set red value 0 to 255
if !exists(global.gLED)
	global gLED = 0 ; set green value 0 to 255
if !exists(global.bLED)
	global bLED = 0 ; set blue value 0 to 255
if !exists(global.wLED)
	global wLED = 0 ; set red value	0 to 255
if !exists(global.ledBrightness)
	global ledBrightness = 255 ; set brightness value 0 to 255
if !exists(global.ledState)
	global ledState = 1  ; this will be toggled between 0 and 1 on each loop

		;loop through all the LED's

			if global.runLED = false

				echo "exiting loop"
				break
			if global.ledState = 0
				echo "next LED on " , iterations
			else
				echo "Next LED off" , iterations

		echo "last LED"
		G4 S{global.ledDelay}
	else
		M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels if we have stopped printing
		G4 S{global.ledDelay}
	G4 S{global.ledDelay}
		
if global.runLED = false
	M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
	echo "exiting daemon"
	M99 ; exit daemon.
		
if state.status !="processing"
	G4 S1 ; if we aren't printing add a delay to give control back to processor

                  To update daemon.g you must first rename it to say daemon.g.old
                  Then upload your new version.
                  It wouldn't hurt to restart after that.

                    I may have not understood how M150 works correctly.
                    I was assuming that each command was applied immediatly and the F parameter only represented where the sequence started.
                    However this piece of information from the documentation suggests that is incorrect and the only F0 commands are applied.
                    The specified RGB values will be sent to the number of LEDs in the LED strip as specified by the S parameter, pushing the existing colours along the strip. To set all the LEDs the same colour, make the S parameter equal to or a little longer than the number of LEDs in the strip

                    Based on that, try this code instead

                    ; 0:/sys/daemon.g


if !exists(global.runLED)
	global runLED = true
	
if global.runLED = false ; send "set global.runLED = false" to stop daemon if needed
	M99 ; exit daemon.  

if !exists(global.ledSize)
	global ledSize = 58 ; modify to number of LED's in neopixel.
if !exists(global.ledDelay)
	global ledDelay = 2 ; modify to change delay. 
if !exists(global.rLED)
	global rLED = 255 ; set red value 0 to 255
if !exists(global.gLED)
	global gLED = 0 ; set green value 0 to 255
if !exists(global.bLED)
	global bLED = 0 ; set blue value 0 to 255
if !exists(global.wLED)
	global wLED = 0 ; set red value	0 to 255
if !exists(global.ledBrightness)
	global ledBrightness = 255 ; set brightness value 0 to 255
if !exists(global.ledState)
	global ledState = 1  ; this will be toggled between 0 and 1 on each loop
	
M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels before we start

while true ; create an endless loop

	if global.runLED = false
		M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
		echo "exiting macro"
		break ; exit loop.
	if state.status ="processing" ; check if we are printing
		;toggle the LED state at each loop
		if global.ledState = 0
			set global.ledState = 1
		else
			set global.ledState = 0
		;loop through all the LED's
		while iterations < global.ledSize - 1 ; set to 1 less than number of LED's in neopixel
			if global.runLED = false
				M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
				echo "exiting loop"
				break
			if global.ledState = 0
				echo "next LED on " , iterations
				M150 R{global.rLED} U{global.gLED} B{global.bLED} W{global.wLED} P{global.ledBrightness} S1 F0
			else
				echo "Next LED off" , iterations
				M150 R0 U0 B0 W0 P0 S1 F0     ; set next LED in loop to either brightness or off
			G4 S{global.ledDelay}
	else
		M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels if we have stopped printing
		G4 S{global.ledDelay}
	G4 S{global.ledDelay}
		
if global.runLED = false
	M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
	echo "exiting daemon"
	M99 ; exit daemon.
		
if state.status !="processing"
	G4 S1 ; if we aren't printing add a delay to give control back to processor

                      Only the first Neopixel turns on. The display shows me counts of cylces and the count of enabled Neopixel.
                      In the first pass of all 58 neopixels, only the first one lights up. it is counted up to 56, then the first neopixel goes out again and stays out. It counts up to 56 again and then it starts all over again

                        Ok
                        I'm clearly not up with M150 so hopefully someone else can help

                        All I can suggest is changing this

                        		;loop through all the LED's
		while iterations < global.ledSize - 1 ; set to 1 less than number of LED's in neopixel
			if global.runLED = false
				M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
				echo "exiting loop"
				break
			if global.ledState = 0
				echo "next LED on " , iterations
				M150 R{global.rLED} U{global.gLED} B{global.bLED} W{global.wLED} P{global.ledBrightness} S1 F0
			else
				echo "Next LED off" , iterations
				M150 R0 U0 B0 W0 P0 S1 F0     ; set next LED in loop to either brightness or off
			G4 S{global.ledDelay}

                        To this

                        		;loop through all the LED's
		while iterations < global.ledSize 
			if global.runLED = false
				M150 R0 U0 B0 P0 W0 S58 F0  ; turn off neopixels
				echo "exiting loop"
				break
			if global.ledState = 0
				echo "next LED on " , iterations
				M150 R{global.rLED} U{global.gLED} B{global.bLED} W{global.wLED} P{global.ledBrightness} S{iterations+1} F0
			else
				echo "Next LED off" , iterations
				M150 R0 U0 B0 W0 P0 S{iterations +1} F0     ; set next LED in loop to either brightness or off
			G4 S{global.ledDelay}
