Add Relay to Z-Probe macro

[Valveman]

My 'Job' for Z-Probing is:
1 G38.2 Z-300
2 G92 Z13.85
3 G91
4 G1 Z2
5 G90
I want to the same 'Job' to include powering on a 12vdc relay, until the probing has finished.
Can all you smart people educate me?
Thanks in advance, Ron.

@Valveman you would normally connect a 12V relay to an OUT connector. You didn't say which board you are using, however the medium-current OUT connectors on Duet 3 boards can be jumpered to be provided with 12V power, which would be correct for your 12V relay. You would control it using the M950 command to set up a GpOut port on that output pin and then M42 commands to turn it on and off.

My 6XD board has OUT_6, 2-Pin KK available. Can it be used as my on/off 12vdc for a small signal relay?

@Valveman yes, if you jumper the VOUTLC for that bank of out ports to 12v , and the other devices on that bank are also ok at 12V

Thanks so much for your assistance. My son has been texting the same info, but I'm still learning to fully understand implementation. M42 will have a P value [got that part], but is the S value a 1=0n and 0=off?

[Valveman]

Well, it took this old geezer long enough, but it works perfectly.

@Valveman yes S is the PWM value to use, so for an on/off device such as a relay, 1 is on and 0 is off.

@dc42 Sorry, I forgot to reply the subject as 'Solved'.
