@t3p3tony I'm getting one e-mail now. All is good. Best regards.

@Norder Oh thank you! This is very good and even easier than picking a scrollbar (if one existed). Because normally I click a scrollbar before using arrow keys I didn't even think to try this because said scrollbar didn't exist. Your suggestion is quite perfect - thank you again.

@deckingman Thank you, I'll try M109 just to learn even though the temperature fluctuation levels out during the skirt printing.

@dc42 Thank you. My firmware is 2.04 so maybe that's why I don't have M308 and an R value?

These are my PID Autotune settings:

M307 P13.1, I0.489, D46.8

Other heater values are:

; Heaters
; -----------------------------------------------------------------------------------------------
M305 P0 T100000 B4092 R4700               ; set thermistor + ADC parameters for heater 0
M143 H0 S120                              ; set temperature limit for heater 0 to 120C

M305 P1 T100000 B4395 R4700             ; set thermistor + ADC parameters for heater 1
M143 H1 S260                            ; set temperature limit for heater 1 to 260C

Thank you @deckingman and @OwenD

Sorry for such a late reply. Our family got the plague and I was last to succumb; I felt quite unwell and could not think. I've finally implemented your advice.

This is is my slicer start code. I've done as you suggest and used M568 in place of M104. Is G10 directly interchangeable with M568? Is one 'better' than the other?

Is there a way to let the let the nozzle heater stabilize before printing of the prime strip begins? Now the nozzle sits as the heater temperature ramps up and as soon as the first layer temperature is reached the prime strip is printed. But because the heater is ramping up it over-shoots by about 5C before dropping to the first layer temperature as the first layer begins. This doesn't seem to be a problem but I'm just wondering if there is a way to avoid the overshoot?

I'm quite clueless with g-code and have mostly hacked together what I have by copying what I've seen elsewhere over time. I sort of understand what your macros do @OwenD but am not entirely sure nor am I sure how these run.

Your slicer end code calls M0 to shut down the nozzle heater? How exactly does that look? Sorry I'm really am clueless with this.

G28 ; home all axes

M140 S{first_layer_bed_temperature} ; set bed temp
M190 S{first_layer_bed_temperature} ; wait for bed temp

G1 X100 Y5 F9000 ; move nozzle over middle of the front of the build plate
G1 Z1.0 F9000 ; lower nozzle 1.0mm from glass

M568 S{first_layer_temperature} ; set extruder temp
M109 S{first_layer_temperature} ; wait for extruder temp

G92 E0
G1 X50 E6 F300 ; extrude a thick line to prime extruder

@OwenD Oh. So for the heater block hear I would do M104 Hn S-276 where n is the heater?

@Phaedrux Thank you; but this M104 doesn't turn off or deactivate the heater block heater.

@weed2all Thank you; but this didn't work: M104 S-273.1

@weed2all said in How to Deactivate the Heater/s?:

@gbartsch M104 S0

I finally was able to look at this. I already was calling M104 in my end g-code but that wasn't deactivating the heater.

M104 S0 ; turn hotend off
M140 S0 ; turn heated bed off
M84 ; disable motors
M220 S100 ; set speed back to default
M221 S100; set flow rate back to 100%
G28 ; home all axes
M18 ; deactivate steppers

Everyone, thank you for all the answers! I'll work with the information you all provided. Best regards ..

It's said there are no stupid questions but this feels like one.

How do I turn off the heater block heater after the print finishes?

I want to put a command in my end g-code to deactivate the heater but can't see how. Clicking the Heater 1 text in the control panel runs some JavaScript but I'm no longer smart enough to figure out what it is.
