Help setting up the m3 spindle on and ok to move.

Good morning.
Help need on configuring a stand alone thc input for ok to move.

I have a Linuxcnc set on my plasma table with 4 axis. All working good

Using a standalone torch high control

Going to use M3 spindle on to to activate the height control on.
I need to configure a wait to ok to move Single from height control.

Not sure how to get started.

You can probably use a timedelay function in HAL

Thaks

I'll see what I can do
