RatOS homing Y speed

When I echo RatOS vars, I get macro_travel_speed: 300. When I look at the homing macro I see {% set speed = printer["gcode_macro RatOS"].macro_travel_speed|float * 60 %}. When I take 300 * 60 I get 18000, but that is the speed after it has hit the endstop sensor. Long story short, how I can see the speed it uses to move to the sensor? Thanks!

That would be homing_speed on the stepper you're homing: https://www.klipper3d.org/Config_Reference.html#stepper Why do you want to know the homing speed?

because I hear a really bad vibration at that speed and when I manually moved Y on different speeds I think I stepped over it, its very precise. In the meantime I found the speed, 3500 makes it vibrate. I posted in troubleshooting about it.

default is 50 mm/s for x / y. You can see the defaults in RatOS/printers/v-core-3/steppers.cfg. And yes, 50 mm/s does sound pretty awful on the 2504AC's depends on current

Thanks @miklschmidt. DId you happen to see the video posted here: https://discord.com/channels/582187371529764864/1098945903752138772/1098948379612033024 I think what you're referring to is the "singing" of the stepper drivers? I don't think that vibration in the video is due to current is it?

No, i'm referring to motor resonance, the range changes with current. I wouldn't worry about that though, you shouldn't be printing at 50 mm/s anyway

Thats true! 😄 Thanks for the help
