[thorny ridge]

[gcode_macro LOAD_FILAMENT]
default_parameter_SPEED: 400 <---- Im not very familliar with klipper what do I have to change here to fix the error
default_parameter_PRIME_SPEED: 300
gcode:
SAVE_GCODE_STATE NAME=__filament__load
M83
G1 E5 F75
G1 E50 F{SPEED}
G1 E35 F{SPEED}
G1 E20 F{PRIME_SPEED}
G1 E-1 F{SPEED}

this attribute was deleted for 3 years in klipper: https://www.klipper3d.org/Config_Changes.html (scroll down to 20121102)

so your macro is just out out outdated... (and i think is also very strange with the SAVE_GCODE_STATE at the beginning...)

Where did you copy the macro from?

[thorny ridge]

a random github

what would you suggest I do instead?

[remote trail]

write your own macro or/and dont copy macros from random (outdated) github repos...

how familiar are you with gcode in general?

[thorny ridge]

not very

I will try to find a more up to date macro thankyou

for now I just replaced all the spots where it calls for the varible with a regular number

[remote trail]

i think this is just fine for this kind of macro

[gcode_macro LOAD_FILAMENT]
gcode:
  M83
  G1 E5 F75
  G1 E50 F400
  G1 E35 F400
  G1 E20 F300
  G1 E-1 F400

you can also remove the SAVE_GCODE_STATE. its not needed here

you can also move the filament faster instead of 400, in the area where your filament will not be pressed threw your nozzle. the 300 part is your purge part. this should be flow. but you have to change the lengh of the first gcodes where it is "loose" in your toolhead (the length between our gears and your nozzle)

[thorny ridge]

in my testing 400 seems fast enough

can I ask you an unrealted question?

Im tuning presure advance

and im using the equation provided pressure_advance = <start> + <measured_height> * <factor>

is <factor> my layer hight?

b/c the measured hight would change based on that

[remote trail]

factor is the value you used before in the command for the test tower

for example this command:

TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=.005

[thorny ridge]

cool

[remote trail]

the last value "FACTOR" is the the factor you need in the calculation

[thorny ridge]

do I have to figure out what layer Im measuring

b/c how does it know what setting it was at for a given hight

[remote trail]

just mesure the height with a ruler

[remote trail]

with this formular

just mesure the height and fill in all values, then you get the value from the special layer/height of your print

[thorny ridge]

I trust you but how does it know what layer im looking at based on the mesured hight

for example i measured 10.17 mm at 0.3 mm layer hight but that would be a completely diffrent layer at 0.2mm layer hight

[remote trail]

the temp tower (the command above) works in mm and not in layer. klipper dont know the layer. only the height

if you want to read more about this command: https://www.klipper3d.org/G-Codes.html#tuning_tower

(every time z_height and now layer count)

[thorny ridge]

oh ok
