Tool w Toolboard knocked off didn't stop, fire hazard

BeosDoc

I have a tool changer system and my tool, hemera extruder with toolboard 1LC and tool selected switch, was knocked off the tool head somehow and sat on the heated bed. Since it has a tool selected ID switch when it was dislodged it should have detected the disconnect (no tool change command issued) it should have stopped extruding and turned off the heater and also stopped/paused the printing (moving the XYZ axis). It didn't do any of that, instead it kept on printing and extruding until it was done printing and then pushing the tool off the bed onto the wooden table (CoreXY and move the carriage back left, out of the way, when finished). Luckily I was here and heard a loud thump, ran in and kept it from starting a fire.

If you have a tool changer with a loaded/mounted tool and has a switch to detect which tool and that it is mounted and all of a sudden gets unmounted or knocked off, during printing, without a command to change tools it should stop or pause the print and stop extruding and turn off the heater! And of course give an error message.

Duet 3, toolboard 1LC using version 3.2-RC2. I looked at V3.2 notes and didn't see any mention of this issue.

How are you monitoring the switch?
Are you using daemon.g?

BeosDoc

Oh forgot to mention Duet 3 is in standalone mode. I shouldn't have to monitor it, the toolboard 1LC has a tool mounted switch switch connection, the firmware should be monitoring it just like it does with nozzle temperature to make sure the heater didn't fall out.

There also was a time before that it wasn't fully mounted and the system gave me a message that I was attempting to extrude from unselected tool but still continued printing with that tool just not extruding.

Hi @BeosDoc It is possible to configure a switch to act as a trigger so that if the switch disconnects it pauses the print. Please share your config.g to see if its setup that way.

This is not something that is automatic as not everyone has a tool board actually on a tool changer with multiple tools, so not everyone has a switch.

BeosDoc

That makes sense. Where's the documentation on how to do that?

Obviously my config.g doesn't have it but here it is anyway:

use an external trigger.
you'll probably have to have some if statements in etc
e.g. if T1 then...

BeosDoc

Sorry, that kinda points me in the right direction but doesn't look like that would cover what is needed.

You can have if statements in g files?

jay_s_uk

@BeosDoc yes. Using meta code.
So when the switch is triggered, the code would then check if that particular tool is active.
