>Pressure Linear Advance<

https://www.klipper3d.org/Pressure_Advance.html?h=pressu pressure_advance = + <measured_height> * .

If the object of the testing is different from the one published on the klipper page

follow these instructions:

my object height is 71,8mm, so taller,

and to test with more precision I do

TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=.002

(instead 0.005)

my height at correct pressure advance is 32mm

Klipper says

Start + (Correct Height * factor)

0 + 32mm *0.002 factor = 0.064

but the factor is increased at every layer, not at every millimiter...

I read from Console:

Starting tuning test (start=0.000000 factor=0.002000)

File selected

File opened: Object.gcode

Size:4485980

pressure_advance: 0.000400

pressure_advance: 0.000720

[...]

so the difference is

+0,00032 at layer

and not 0.002

(maybe it changes because my object is taller than the one is on klipper test page)

measured_height printed object 71,8mm/359 layers (read on klipper) = 0.2mm layer height

it's correct as I set in slicer.

The height with the correct pressure advance = 32mm

32mm / 0.2mm = 160° layer

160 * 0,00032 = 0.0512 of pressure advance

otherwise

in console check the last command, in my case:

pressure_advance: 0.11488

71.8 : 0.11488 = 32 : X

same result!

mount them below the bed support, not above: the weight of the bed must compress them.

Pleas norw: you cannot ABORT the TUNING_TOWER but try to insert during the test TUNING_TOWER COMMAND=SET_PRESSURE_ADVANCE PARAMETER=ADVANCE START=0 FACTOR=0
