M573 Heater PWM Logging

[helpimlost]

Is there an easy way to log the values given by M573 into a text file with M118 or M929? I'm not entirely confident about how M118 works but it looks like it only logs a string. I can use a loop to continuously report M573 values and have that be reported into a text file with M929 but I would also like to have the layer height or print speed be in the same output line as the M573 value. I figured the best way to do that would be with an echo.

Also, I've tried setting M573 values as a variable which I could then echo but it seems you can only set object model items as variables. I could be completely wrong on some of this so feel free to educate me if I am.

if {heat.heaters[1].current >= 50}
	M929 S3
	
	while {heat.heaters[1].current >= 50}	;Check hotend is over 100 C
		var <heat1pwm> = <M573 P1>
		echo "Heater 1 PWM: " ^ {var.heat1pwm} 
	end
end

Hardware is a Duet 3 + SBC running RRF 3.3RC3.

@helpimlost I will need to add the current PWM to the object model before you can log it.

@dc42 Understood. Thanks!

@helpimlost I will add this in RRF 3.4.
