How to use tuning tower for speed calibration?

Hi, I would like to somewhat automate speed tuning, but I am not sure how to combine M220 GCODE and TUNING_TOWER klipper command.

How to use tuning tower for speed calibration?

[junior mountain]

TUNING_TOWER COMMAND=SET_VELOCITY_LIMIT PARAMETER=VELOCITY START=100 STEP_DELTA=50 STEP_HEIGHT=10

its easy:
COMMAND=SET_VELOCITY_LIMIT
means that the tuning tower executes every x mm the gcode command SET_VELOCITY_LIMIT

then you can watch in the klipper doku to see what parameters are available

Funny, did look in klipper G-Codes for something velocity related, and missed it somehow. Thanks 8)

you can set:
VELOCITY ACCEL ACCEL_TO_DECEL SQUARE_CORNER_VELOCITY

or you can use any other Gcode command

this way you can cahnge any value you want with the tower

Can I? Example with M220 please

[junior mountain]

why M220?

[cedar coyote]

(It is just any random G-Code which accepts value in weird format)

like M220 S120 -> relative speed 120%

[junior mountain]

but in klipper you set the global EM with M221

I got the fact that I can use SET_VELOCITY, but you said - any other GCODE

[cedar coyote]

uh, sorry

[junior mountain]

but why using M220 if you can use the native klipper command set_velociuty_limit, this doesnt make any sense

[cedar coyote]

Please don't take my questions so literally, I'm just wondering how to use TUNING_TOWER with something that doesn't take a named arguments.

[junior mountain]

well, sorry for hte misunderstanding, i thought you want to know how to use the tuning tower for speed changes, like you titled this thread

try to use klipper real name gcode commands instead of Mxxx

[cedar coyote]

you are right, you provided the answer for this, I am thankful, but you did mention this, quote "or you can use any other Gcode command", so that is why I asked, how to use other Gcode in TUNING_TOWER 😅

[cedar coyote]

Got it. Thanks

[junior mountain]

use klipper gcode commands

btw, you can easily make a Gcode Macro that accepts a prameter and then calls M221 or whatever you want
