2-speed spindle configuration - help

Thank you Andy.
today I tried to break up your "gearchange.comp"
by
www.forum.linuxcnc.org/10-advanced-confi...-configuring?start=0

can you advise me on configuration.
I do not use hy_vfd (huanyang vfd).
what to replace:

loadusr -W hy_vfd -d /dev/ttyUSB0

net spindle-at-speed hy_vfd.spindle-at-speed

net machine.on.delayed hy_vfd.enable

net spindle-enable hy_vfd.spindle-on gearchange.0.spindle-on
net spindle-cw hy_vfd.spindle-forward
net spindle-ccw hy_vfd.spindle-reverse

well thank you

It's hard to say, as I have no idea what your spindle control pins are called. But use what you have.

It's done

Hope "it's done" means you got the 2 speed transmission wording !
If so would you share your newer HAL an INI files ?
Thank's

Yes , 2 speed transsmision is working nice.

Thank You very much
