Reading GCode

Ender Series Creality Ender-3 S
1

Where in the G code does it say what the nozzle temperature and bed temperature is set? I had Cura set to a nozzle temperature of 240 C, when my print starts, my Ender 3 S1 Pro says it’s going to start at 260 C. I look at the first hundred or so steps and I did not see a 240 or 260 value.

M104 or M109 Sets hot end temperature

[

M104: Set Hotend Temperature

Set a new target hot end temperature and continue without waiting. The firmware will continue to try to reach and hold the temperature in the background.

example code from cura for S1 pro

M140 S70 ’ Set Bed Temperature
M105
M190 S70
M104 S210 ’ set temperature to 210
M105
M109 S210
M82 ;absolute extrusion mode

M204 S1000
G0 F3600 X76.467 Y157.

Thanks Bill, I see the 104 now. I’ll watch the print more closely to see if it is reading the GCode properly.

Also check the machine settings in cura

My settings before I installed a sonic Pad are-

; Ender 3 S1 Pro Start G-code

; M413 S0 ; Disable power loss recovery

G92 E0 ; Reset Extruder

; Prep surfaces before auto home for better accuracy

M140 S{material_bed_temperature_layer_0}

M104 S{material_print_temperature_layer_0}

G28 ; Home all axes

G29 ; If you require bed levelling before each print

G1 Z10.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed

G1 X0 Y0

M190 S{material_bed_temperature_layer_0}

M109 S{material_print_temperature_layer_0}

G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position

G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line

G1 X0.4 Y200.0 Z0.3 F5000.0 ; Move to side a little

G1 X0.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line

G92 E0 ; Reset Extruder

G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed

G1 X5 Y20 Z0.3 F5000.0 ; Move over to prevent blob squish

Thanks Bill, I will check those settings.
I have one other question not necessarily on this topic, but maybe you can answer it? Periodically I manually reset the bed leveling before running the auto level function - my question is about the Z offset, is this a finite number or is it only relative to the bed? In other words, what should that Z offset setting be before I manually level to bed? Maybe if it’s only relative to the bed, it doesn’t make any difference until after bed leveling ??

I can not help with the Z offset as my first use of the s1 pro wase to replace the display with a sonic pad running klipper. I used macros to do all the calibrations.

Mybe someone with a standard S1 pro may be able to help you.
