#Before layer change - pressure advanced

I'm trying to figure out my pressure advance a little different for a project i'm running. I would really like to do it like I did my fan test. Does anyone know what I would need to do something like this but for pressure advanced?... I would really like it to change every layer instead of every 10 if possible. I searched and couldn't find anything. Thanks for any help, Cody

;BEFORE_LAYER_CHANGE - fan
G92 E0.0
;[layer_z]
{if layer_z>=1.05} M104 S220 M109 S220 {endif}
{if layer_z>=11.05} M104 S225 M109 S225 {endif}
{if layer_z>=21.05} M104 S230 M109 S230 {endif}
{if layer_z>=31.05} M104 S235 M109 S235 {endif}
{if layer_z>=41.05} M104 S240 M109 S240 {endif}
{if layer_z>=51.05} M104 S245 M109 S245 {endif}
{if layer_z>=61.05} M104 S250 M109 S250 {endif}
{if layer_z>=71.05} M104 S255 M109 S255 {endif}
{if layer_z>=81.05} M104 S260 M109 S260 {endif}

What firmware are you using

spring wigeon
#

Whatever you call bambu x1c firmware.

#

I've got this, but haven't tried it yet. I found it in an old post. I don't know if it will work or not. I do see m900 is used in orca tower tests. changes every 10 layers for 300 layer test.

#

;BEFORE_LAYER_CHANGE 300 layer test
;[layer_z]
{if layer_z <= 1}
M900 K0.02
{elsif layer_z <= 51}
M900 K0.03
{elsif layer_z <= 101}
M900 K0.04
{elsif layer_z <= 151}
M900 K0.05
{elsif layer_z <= 201}
M900 K0.06
{elsif layer_z <= 251}
M900 K0.07
{endif}

#

I would really like finer detailed changes per layer, but...

spring wigeon
#

I guess once it close i can change the number to .xxx

mint rose
# 
{elsif layer_z == 2}M900 K0.01
{endif}```

It will change before each layer, you just have to follow the same scheme for as the amount of layers as there will be or you want to

Ok, so for a 60mm test piece that would have 300 layers at .2 layer height, I would have to copy, paste, and edit this number 300 times?

mint rose
#

yes, no other choice because Orca doesn't support custom vars

#

that said, 300 layers seems a bit exaggerated for testing PA, if that's the goal

spring wigeon
#

I thought there would be a way to 1. Read K valve 2. add .001 to k valve at next layer

mint rose
#

this would have been possible with something like this M900 {pressure_advance[0] + 0.05} but pressure_advance is not updated at each layer, it's the global setting defined in the filament preset (read only value)

#

I basicly want to run the PA Tower code on my own Test STL. I want to put the seams and corners the way I want to test them.

mint rose
#

your bambu machine runs a variant of klipper (probably) so I think it would be possible to tell Orca to call a macro, instead of making an if statement 300 times

#

basically something like [get current PA, add a value, set new PA]

mint rose
#

is your OS Windows?

I was just thinking about writing a little CMD script that would make avoiding the annoying copy/paste task

#

but this would make more sense to do it in a sheet so every one could benefit

no, it's a hassle in cmd format since defining floating values to vars is not supported
