changing max velocity on startup

Hi.

On the current machine that was been retrofited with linuxcnc, it have a selector for the machine max velocity:





how can read and set the max velocity when linuxcnc starts up?

halui.max-velocity
using a switch requires using the direct-value option and a mux or somethimg similar
set the scaling to get percent, then have a mux component out put 25,50,100 % depending on the switch position.

that was what I used, but, for example, if I left the machine on 25%, next time I start linuxcnc it will be set at 100%. only if I make a change on the switch it will update.

The pin halui.machine.is-on toggles when the power button (F2) is pressed. Maybe you can use this to toggle the logic.
