HSD spindle tool eject

[Desertboy]

How does the tool eject work?

I ran air to it but the button doesn't eject the tool

I'm midway a controller swap on an AXYZ and the spindle's not running from controller

Does it need some feedback to work?

It's a 3.7kw HSD

How does the button work????

Check your WhatsApp. It needs 24V and 0V to the correct pins on the 'control' plug of the HSD spindle.
