Macro- relay on/off

[Mario Soto]

Hello,
Is it possible to write a macro that would automatically turn on a relay when the z-axis is moving down and off on the up?
Thank you.

You could just wire your relay to the direction pin of the z axis stepper driver output

The direction pin doesn't tell you if it's moving or not, just whichever way it moved last.

true, but there is no tri-state in "on or off". If you need two relays, on for up and on for down you would need to work out something else, depends on the application.

Thank you for the replies. I did not explain correctly in my question. The relay has to stay on until the z changes direction. In other words, the z going down triggers a pneumatic cylinder and stays activated, then releases it when the z moves upward.
Thank you.

[Mario Soto]

Would the relay say active when the z is at the bottom but not moving and then go off when it starts to go up?

[Mario Soto]

Great! Thank you very much. But you're assuming I'm smart and I'm not! I put the macro in the macro folder. The pin for the breakout board to activate the relay is pin 3 so I take it I would change to 2 in the macro to 3? Do I need to put the macro number in the program? I always used Mach3 and am now changing over to this software. Thank you again.

[Mario Soto]

Yes, indeed it does stay on til reversed. ( 07) So now how do we get it to do this when the program is running?
Sorry I did not see the 9091 I will try it next

[Mario Soto]

Yes, I think that's it! I'll give it a try on the machine.
Thank you very much!
