Emergency Stop Button
-
Hi Guys,
I'm trying to add a physical emergency stop button as an extension to the software emergency stop, to stop everything except the fans (in case the the tools are hot).
I have a Mushroom button connected in N/C to io4 3.3v and in, with the following at the bottom of my config.g, but it just doesn't work. What have I got wrong;

@Dizzwold looks fine to me config wise. how do you have it wired?

Forgot this in my post;
FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.4.5 ELECTRONICS: Duet 3 MB6HC v1.01 FIRMWARE_DATE: 2022-11-30 19:35:23Hi Jay s,
Thank you for your reply.
I did have it wired to io_4, '3.3v' and 'in'.
I've then tried it with 'in' and 'gnd', which made it work when releasing the emergency stop button.
So I changed;
M950 J1 C"io4.in"
to
M950 J1 C"!io4.in"; Emergency Stop M950 J1 C"!io4.in" M581 P1 T0 S0 R0 M582 T0Which now seems to work.

FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.4.6 ELECTRONICS: Duet 3 MB6HC v1.01 FIRMWARE_DATE: 2023-07-21 14:11:38Yet more issues with this emergency stop button.
I've had to disconnected everything an move the printer. Just fired it up, and no end of issues.
I've found that this was caused by the Emergency stop button.
I've tested the switch to check it's connected and working.
Connected to the NC terminals of the switch.
Wired to "io4 in"and 3.3v
With the following code. The machine runs as normal without the button press, but when I press the button, nothing happens. It does not switch everting Off?
; Emergency Stop M950 J1 C"io4.in" M581 P1 T0 S0 R0 M582 T0If I invert the code its just in a perpetual emergency stop.
Any ideas?
Dizzwold.
