Filament monitoring attached to U axis on

@India Define a tool that uses both extruders, then use something like G1 E100:0 to extrude from one, and G1 E0:100 to extrude from the other. Alternatively, set it up as a mixing extruder with M567, and adjust the mixing ratio before extrusion.
From G1 notes:
Where a tool has more than one extruder drive then Ennn:nnn:nnn etc is supported to allow for the individual movement of each to be controlled directly. This overrides the extruder mix ratio set with M567

@droftarts thanks for your quick response
Can you please tell me, how to define a tool that uses both extruder -
@India See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m563-define-or-remove-a-tool, particularly the description of the D, H and F parameters.
Example:
M563 P2 D0:1 H1:2 F0:2 ; create a tool using extruder drives 0 and 1, heaters 1 and 2, and fan mapped to fans 0 and 2Ian

@droftarts thanks for your help.
As per your suggestion, I am able to configure two extruder E0 and E1 .
.
M563 P0 D0:1
G10 P0 X0 Y0 Z0 ; set tool 0 axis offsets
G10 P0 R0 S0
T0:1 ; toolAfter this I tried to monitor the filament runout using sensor BIGTREETECH by inserting the code in config.g as
M591 D1 P7 C"e1stop" L7 R50:200 E5 S1 ;configure BTT smart filament sensor
M591 D1 ; display filament sensor parameters for extruder drivewhere i have attached it to "e1stop" and run a two line g-code from SD card as
G1 E0:50 F180
G1 E0:-50 F180
i found error shown in figure.
M591 D0 shows that there is no sensor (here I don't want to monitor the filament as it used for extruding liquid)
M591 D1- shows the sensor attached to it and where I want to monitor the filament.
so based on above can some one guide me

@India What firmware version are you running? Send
M115in the console, and post the response.Ian

please find the response of M115

@India Please update to 3.4.6 and test again.

@droftarts Thanks, I have updated the firmware to 3.4.6. Now it is not showing the problem as I was facing in old version.
Now filament sensor showing no calibrated data only as shown below
I have tried printing two line code from SD card (G1 E0:200; G1E0:-200) but it is not able to calibrate.
The code I have used to configure the sensor is
M591 D1 P7 C"e1stop" L7 R50:200 E22 S1I am little confused about the R and E value , can u please suggest me how to get these value

@India I don't have a BigTreeTech filament monitor to test, it isn't manufactured by us, and I don't know if the way you have set it up is correct. Please refer to the BigTreeTech documentation, or at very least provide a link to it so I know which version you have: BTT have produced two, V1 and V2, which do you have?
According to the documentation here, the configuration should be:
V1 (which appears to be what you have, and have set)M591 D1 P7 C"e1stop" L7 R75:125 E22 S1V2
M591 D1 P7 C"e1stop" L2.88 R75:125 E9 S1If your configuration is correct, I don't know how many points counts as calibrated, but I doubt just extruding and retracting 200mm is enough to calibrate it. It really needs to start a print, so enough data can be collected, particularly if you are using a V1, which has larger distance between points sampled. Use the E parameter suggested; the R parameter is just for how sensitive you want the monitor to be.

@droftarts thank you sir.

@India Did you get it working? If so, please let us know, and what steps you took, so the information is here for other people, and so I can mark the thread as solved.
