e-stop does not switch ps_on pin
-
Hi!
I put a physical e-stop to my printer and have a question, as the title suggests:
I wired everything as it says in docs. Now it works like the e-stop in DWC: Stop all motors and turn off all heaters. So far so good.
As it says at section "Cut the 12/24V supply" it should even shut down my 24V circuit. However, this is not happening with my setup, but I can toggle the PSU with M80 and M81 via DWC.
further details of my setup:

My guess is, that it’s a bug in that region - or is this part of the docs just outdated because shutting off 24V would mean no cooling fan?Thanks for your time!

@marvineer PS_ON is NOT changed by a software E-STOP. The reason is fairly simple; if you have (high temperature) heaters surrounded by parts that could melt, cutting power to the fans may result in physical damage. If you want to turn off the PS_ON pin using an external trigger, consider writing a macro that turns it off via
M81before it callsM112. -
@marvineer As @chrishamm says, M112 doesn't switch off PSU power, and hasn't since RRF v2. The guide is quite old, and as much as I try to check things as I'm migrating them, I missed this. I'll update the guide and the M112 description to reflect this.

perfect, that would resolve my confusion. Thanks to all of you
