6HC+1LC where connect filament sensor?
-
After reading the documentation I'm confused -- with my combination, do I have to connect the filament sensor to the 1LC (where my extruder is connecter)?
I do not want to add weight on the toolhead so was planning on having the filament sensor on the frame instead, connected to the 6HC. Surely this must be possible?
I have both the Duet and Dyze sensor if it makes a differens.
-
@Reine at the moment its not possible to add a filament sensor on another board other than where the extruder is (although it has been requested by myself and others). You could run a separate wire from the filament sensor to the 1LC to get it to work but sort of defeats the purpose of CAN-FD.
-
@jay_s_uk that's an interesting design choice. I don't know what the bandwidth is on the can interface, maybe there some limits there?
However for a simple binary switch, that only senses filament or no filament I can't see the need for having it on the same board as the extruder.
Too bad it's not possible at the moment and as you say, another wire defeats the purpose of CAN-FD.
-
@Reine If you're only detecting the presence of filament you are supposed be able to wire a simple switch type monitor (1&2) to any board. Not positive if it was really implemented in 3.4+ or not. But I remember seeing some traffic on the subject.

@Nurgelrot not possible currently

@jay_s_uk Thank for checking I could have sworn that they added an exception for the the simple switches. Might be able to reproduce the same functionality with a trigger? M581.
Or do what I do and mount the filament monitor to the frame and run the wire down with the boden tube. Sucks but its the best I could come up with.

@Nurgelrot M581 should work although segmentation
M669 S1 T1
may also have to be used -
@Nurgelrot said in 6HC+1LC where connect filament sensor?:

This is planned but not yet implemented.
-
@dc42 any idea when this will be implemented?
-
@Reine it's already implemented in the 3.5 source code, but untested.

but untested.
Can I use it already, or it needs to be tested and then released?

@zambz2016 simple switches were implemented in the 3.5.1 release
