spindle orient M19 Fanuc motor

is it possible to add manual tool release in hal ?
the tool is only released when the button is pressed when the spindle is turned off
the spindle can turn as the tool clamp.
or to use a ClassicLadder

I'm sure it is possible. But you will need to be responsible for the safety interlock logic to make sure that the spindle can only be manually opened at the appropriate time.

Yes, I have such a setup on my mill. In my implementation it only allows tool release when the spindle is stationary. But other logic is possible.

I made a custom HAL component to handle it. You can't really use spindle-is-on as that goes false some time before the spindle actually stops.

This is probably more of a concern for a lathe than a mill.

Contains the spindle_interlock.comp that I wrote. It also prevents the spindle starting when the tool is released.
