Multi extruder & filament sensor

[JaapVis]

Hi,
I modified a Stacker 4 extruder printer with an Duet 3 board, running Firmware 3.2, it works real great but there is one issue and maybe there is some one solved this.
This machine is running at the same time with 4 extruders with the following commands in the config:

M563 P0:1:2:3 D0:1:2:3 H1:2:3:4 F11:12:13:14
M567 P0:1 E1:1:1:1

There is one tool T0 defined and all the extruders are running, so far no problem.
In the meantime I added laser filament sensor and these work with the latest firmware oke.
So I define these sensor with the command:
M591 D0 P5 C"io2.in" R10:120 E3.0 S1
M591 D1 P5 C"io7.in" R10:120 E3.0 S1 ; etc.

now the trick how can I trigger the other three sensors because T0 only see sensor D0 and not D1 etc. and soon I activate D1 sensor the machine pause immediately caused by sensor D1.
What is a work around to have all sensors working with T0?

Best regards, Jaap Vis

@jaapvis, it should work already, as long as the mix includes D1. Have you tested it? If you have and it doesn't work in firmware 3.2, try firmware 3.3beta3.

@jaapvis said in Multi extruder & filament sensor:

@dc42, what do you mean by "as long as the mix includes D1" ?

What I do is follow:

M563 P0:1:2:3 D0:1:2:3 H1:2:3:4 F11:12:13:14 to set 4 extruders to tool D0.

And the mix ratio
M567 P0:1:2:3 E1:1:1:1

Finally the sensor:
M591 D1 P5 C"io7.in" R10:120 E3.0 S1 (sensor on second tool)

Above doesn't work...

@jaapvis have you run M591 D1 without parameters, to check that communication with the sensor is working?

[JaapVis]

@dc42 Yes communication is working, see pictur.

@All

Is there someone with a solution for this issue?
